NEWS East London LETTER Bromeliad Society September 2016 South Africa Established: 25 July 2009 Our aim is to promote and encourage awareness and interest in Bromeliads in East London and all of South Africa! ELBS is an Affiliated Society of Bromeliad Society International August Meeting On a scorcher of an afternoon, 38*c in the shade! 26 of us gathered under the trees at the home of Dudley and Albie Reynolds for an extremely interesting meeting. If you were not there, you seriously missed out as Dudley shared his passion for Aechmea orlandiana and its cousins, plus we got to drool over loads of his own fabulous varieties of this family of bromeliads that he used to enhance his very interesting talk. There was a lot of discussion from the crowd which made for an interesting afternoon. Even though we are just coming into Spring, these bromeliads were just stunning. The further we move into summer, with stronger light, the true colouration of the leaf markings will still emerge. Dramatic Leaf Colouration of Aechmea orlandiana and its Cousins - by Dudley Reynolds . My talk is based on my book with the above title in which I describe 20 varieties of Aechmea orlandiana and its close relatives, cultivars and hybrids. The description of the leaf markings are my own visual perception I have experienced growing these plants. Aechmea orlandiana with its dramatic leaf colouration has been one of my favourite bromeliads and has been in my collection for the past 30 years. Grown as an epiphyte, the zig-zag , maroon to brown leaf markings can be properly appreciated at eye level. The stoloniferous growth pattern makes it a lovely plant to mount and grow epiphytically. Aechmea 'Medio Picta' is a cultivar of Ae. orlandiana and has an almost solid brown to maroon central leaf area. ‘Medio picta’ means 'painted centre'. Aechmea 'White Knight' is a large upright rosette cultivar of Ae. orlandiana and has lovely colour combinations of brown, maroon, Aechmea ‘Medio Picta’ Aechmea ‘Rainbow and Aechmea ‘White Knight’. Next meeting: Sunday 25 September at 2.00 pm. Hosted by Denise O’Hagan, 14 Aloe Road, Beaconbay. Bring your chair , a mug, and one of your broms to brag about! See you there! East London Bromeliad Society South Africa September 2016 Page 1 Aechmea ‘Ensign’ Aechmea ‘Reverse Ensign’ green and pink markings on a cream leaf. Aechmea 'Rainbow' is a cultivar of Ae. orlandiana and is aptly Aechmea ‘Gold Tone’ named 'Rainbow' as it sports a kaleidoscope of colour, infused with pink when grown in strong light. Aechmea 'Pickanniny' is a hybrid cross between Ae. orlandiana , 'Bert' and Ae. fosteriana . This Aechmea ‘Rainbow Snowflake’ plant has more prominent black markings on its shiny green leaf, which is narrower than a lot of crosses. I have also observed that the trichomes are more visible on this hybrid due to the leaf colouration. Aechmea 'Glowing Embers' is a hybrid crossed from Ae . 'Shadow' and Ae . 'Pickanniny'. The dark barring on the leaves are infused with dark pink when grown in good light. The plant has a very upright form, which probably stems from Ae. fosteriana . Aechmea 'Hayward' has subtle colouration compared to the rest of the varieties described, but never the less, is still very attractive and comes in a few different variations. Aechmea 'Ensign' is very popular amongst collectors, due to the lovely albomarginated leaves, the pinks prominent on the white areas, and Aechmea ‘Bert’ maroon on the green areas of the leaf. I find this form more attractive when grown in high light. However, depending on your taste, a plant grown in shadier conditions produces more elongated leaves and the contrast between green and white is also pleasing to the eye. Aechmea 'Rainbow' x 'Snowflake’ is a delightful combination of good traits from both parents. The colours are accentuated on the cream base colour of the leaf. Aechmea 'Reverse Ensign' is a sport of Ae. 'Ensign'. The leaves are variegated. Although it does not match Ae. 'Ensign' s pink markings, it is still an attractive plant. Both of these forms do not enjoy cold weather under 10*c and severe leaf burn may occur. Aechmea 'Gold Tone' is a yellow variegated sport of Ae. orlandiana . One of my favourites and for good reason. The different blends of pink, maroon, brown green, yellow/gold makes it stand out in a crowd. And then there is Aechmea orlandiana cv. 'Pink'. The pink which is very prominent on the leaf , gives this one the real 'WOW' factor. Aechmea 'Jean Merkel' is also described as 'medio picta' . I find the central dark colouration more prominent towards the central reservoir. Aechmea fosteriana is a tubular species with matt green leaves and irregular banding on the outer leaf. The inflorescence is more branched Aechmea fosteriana , one of the parents than Ae. orlandiana and extends way above the leaves and can be of Aechmea ‘Bert’ quite pendulous due to its weight. Aechmea correia-araujoi another species, has light green leaves, banded with dark brown which are edged with purple. Although very attractive, it is also a cold sensitive species. East London Bromeliad Society South Africa September 2016 Page 2 Aechmea 'Bert' is a hybrid from Ae. orlandiana and Ae. fosteriana . It has the best characteristics of both parents and the inflorescence is the same as Ae. fosteriana . Aechmea 'Bert’ variegated, is a lovely form of Ae . 'Bert'. Pink colouration appears on the longitudinal stripes which are cream and green. Lisa Vinzant of Hawaii crossed Ae. correia-araujo i and Ae. orlandiana and named it Aechmea 'Haiku'. I can see a lot of the parent Ae . correia-araujoi in this plant. The markings are a little darker and the inflorescence is shaped the same as Ae. correia-araujoi presenting itself well above the leaves. I have also described Ae .

'Black Beauty' an order with Dudley for and shows a lot of potential in the dark leaf colouration on the the book he has written. green underlay infused with a dark pink, almost a red colour appearing on the edges of the dark markings, which makes it a very exciting prospect. Aechmea 'Pali Ridge' is a hybrid between Ae. correia-araujoi and Ae . 'Bert'. My example of this plant seems to be prone to leaf markings due to cold temperatures, although only imported last season. I will review my opinion on this plant once it has endured another winter. The largest factor that influences these plants is bright sunlight, which brings out the amazing, dramatic combinations of leaf colouration which is my biggest attraction to these bromeliads. I HOPE YOU ENJOY THEM AS MUCH AS I DO! Show and Tell Lyn Wegner brought her Fosterella micrantha to show us. This was the first time we had seen a plant from the genus Fosterella . I find it an interesting plant if not the most exciting! It has extremely soft leaves which the snails and slugs love! It is of the Pitcairnioideae subfamily and is found in Mexico, Guatemala and El Salvador where it is pollinated mainly by insects. It is easy to grow in semi shade and requires well drained soil. Some slow release fertiliser will keep it looking good. Lyn also showed Tillandsia xNidus. This is a natural hybrid found in Mexico between T. fasciculata and T. ionantha . It gets its size from T. fasciculata and the beautiful form resembles an enormous T. ionantha! I imported this particular beauty some years ago and didn’t realize just how spectacular it would be! It is a lot larger than the other forms in my collection. I Fosterella micrantha grow mine in a sunny spot and it hasn’t been fertilised for some years! A struggle to keep up with it all but I plan to get my fertilizing act together! Paul Isley mentions it can grow up to 30cm! Lyn’s Tillandsia xNidus Dudley Reynolds showed his Ananas lucidus which is slowly producing its tiny mini pineapple, which is the inflorescence. David Flint talked about his research into Ananas and the therapeutic benefits of eating them. He also brought pineapples along for everyone. Thanks David! Spring Garden Fair - Brenda Wegner Ananas lucidus Members of the East London Bromeliad Society spent an enjoyable three days at the Spring Garden Fair held at Pioneer Nursery from Friday, 12 th – Sunday 14 th of August. Our display stand was set up on the Thursday afternoon and after much manoeuvring and repositioning of plants the stand looked fabulous at the end of the day. A very big thank you must go to Dudley Reynolds and Lynn Friend for the props and to all the members who assisted with the stand setup, display plants, plant donations for the raffles and giveaways, Larraine for photocopying and last but not least to the members who gave up their time to sell raffle tickets and chat to the public. Two talks were held on Saturday, Dudley spoke on Tillandsia and Dr Pete Pfister covered Mounting. Lyn’s talk East London Bromeliad Society South Africa September 2016 Page 3 on Sunday was a general overview of bromeliads, different genera, colouration and form and growing conditions. The society gained two new members, Geoff Howes and Lisa Voges. The three days seemed to fly by and it was wonderful to Dr Pete Pfister and Brenda Wegner were part of the group hear all the comments and compliments from the that set up this magnificent display! public. A great platform to show off these amazing and diverse plants and hopefully whet some appetites and encourage more interest in planting and growing bromeliads in East London.

    BOH: a Unique Chemical for the Induction of Flowering in Bromeliads

    BOH: A Unique Chemical for the Induction of Flowering in Bromeliads Héctor R. Cibes and A. Santiago Nieves1 INTRODUCTION The pineapple family, Bromeliaceae, is composed of stemless herbs native to tropical America whence they have been disseminated to other areas of the world. They have stiff and sometimes spiny leaves. Their flowers are borne in panicles. Perhaps the most important genus of the family is Ananas, to which the commercial pineapple varieties belong. Other members of the family are noted for the fiber obtained from their leaves. Bromelia pinguin L., or wild pineapple, a native of the West Indies, is widely used as a hedge plant and its fruit is also known to contain a proteolytic enzyme. The genus Bromeha was named after the Swedish botanist, Olaf Bromelius. Bromeliads are becoming increasingly important as ornamental plants, both locally and in the United States. Not only the plants themselves are showy, because of their color, shape, and variegation, but also their flowers are beautiful. An important characteristic among bromeliads is that their flowers are long-lasting on the plants. Some will last, attached to the mother plant, for months without losing their beautiful appear­ ance. FLOWER INDUCTION However, flowering is not uniform in this group of plants. For instance, a pineapple field may flower sporadically 10 to 15 times throughout the year, after attaining the proper age. Thus, flower-forcing during a con­ venient time along the growing season is imperative in commercial plant­ ings. This is attainable through the use of suitable concentrations of either calcium carbide (CaC2), naphthalene acetic acid (NAA), or /3-hydroxyethyl hydrazine (BOH).

    An Alphabetical List of Bromeliad Binomials

    AN ALPHABETICAL LIST OF BROMELIAD BINOMIALS Compiled by HARRY E. LUTHER The Marie Selby Botanical Gardens Sarasota, Florida, USA ELEVENTH EDITION Published by the Bromeliad Society International June 2008 ii INTRODUCTION TO EDITION XI This list is presented as a spelling guide for validly published taxa accepted at the Bromeliad Identification Center. The list contains the following information: 1) Genus number (the left-hand number) based on the systematic sequence published in the Smith & Downs monograph: Bromeliaceae (Flora Neotropica, number 14, parts 1-3; 1974, 1977, 1979). Whole numbers are as published in the monograph. 2) Species number (the second number) according to its systematic position in the monograph. Note: Taxa not included in the monograph or that have been reclassified have been assigned numbers to reflect their systematic position within the Smith & Downs framework (e.g., taxon 14.1 is related to taxon 14). The utility of this method is that one may assume for example that Tillandsia comarapaensis (150.2) is related to T. didisticha (150) and therefore may have certain horticultural qualities in common with that species. 3) Genus and species names follow the respective numbers. 4) Subspecific taxa (subspecies, varieties, forms) names are indented below the species names. Note: Variety "a" (the type variety) is not listed unless it contains a form (see Aechmea caudata ). Similarly, the type form is not listed. 5) Author name follows the specific and subspecific names. These names are included for the convenience of specialist users of the list. This list does not contain publication data or synonymy, as it is not our intent for it to be a technical nomenclatural guide.

[email protected] 2El Colegio de la Frontera Sur - San Cristóbal de las Casas, Laboratorio de Análisis de Información Geográfica y Estadística, Chiapas, México. [email protected] ABSTRACT The current knowledge of the bromeliad flora of the state of Oaxaca, Mexico is presented. Oaxaca is the Mexican state with the largest number of bromeliad species. Based on the study of 2,624 herbarium specimens corresponding to 1,643 collections, and a detailed bibliographic revision, we conclude that the currently known bromeliad flora for Oaxaca comprises 172 species and 15 genera. All Mexican species of the genera Bromelia, Fosterella, Greigia, Hohenbergiopsis, Racinaea, and Vriesea are represented in the state. Aechmea nudicaulis, Bromelia hemisphaerica, Catopsis nitida, C. oerstediana, C. wawranea, Pitcairnia schiedeana, P. tuerckheimii, Racinaea adscendens, Tillandsia balbisiana, T. belloensis, T. brachycaulos, T. compressa, T. dugesii, T. foliosa, T. flavobracteata, T. limbata, T. maritima, T. ortgiesiana, T. paucifolia, T. pseudobaileyi, T. rettigiana, T. utriculata, T. x marceloi, Werauhia pycnantha, and W. nutans are recorded for the first time from Oaxaca. Collections from 226 (of 570) municipalities and all 30 districts of the state were studied. Among the vegetation types occurring in Oaxaca, oak forest is the richest with 83 taxa, followed by tropical deciduous forest with 74, and cloud forest with 73 species.
  • Nuclear Genes, Matk and the Phylogeny of the Poales

    Nuclear Genes, Matk and the Phylogeny of the Poales

    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2018 Nuclear genes, matK and the phylogeny of the Poales Hochbach, Anne ; Linder, H Peter ; Röser, Martin Abstract: Phylogenetic relationships within the monocot order Poales have been well studied, but sev- eral unrelated questions remain. These include the relationships among the basal families in the order, family delimitations within the restiid clade, and the search for nuclear single-copy gene loci to test the relationships based on chloroplast loci. To this end two nuclear loci (PhyB, Topo6) were explored both at the ordinal level, and within the Bromeliaceae and the restiid clade. First, a plastid reference tree was inferred based on matK, using 140 taxa covering all APG IV families of Poales, and analyzed using parsimony, maximum likelihood and Bayesian methods. The trees inferred from matK closely approach the published phylogeny based on whole-plastome sequencing. Of the two nuclear loci, Topo6 supported a congruent, but much less resolved phylogeny. By contrast, PhyB indicated different phylo- genetic relationships, with, inter alia, Mayacaceae and Typhaceae sister to Poaceae, and Flagellariaceae in a basally branching position within the Poales. Within the restiid clade the differences between the three markers appear less serious. The Anarthria clade is first diverging in all analyses, followed by Restionoideae, Sporadanthoideae, Centrolepidoideae and Leptocarpoideae in the matK and Topo6 data, but in the PhyB data Centrolepidoideae diverges next, followed by a paraphyletic Restionoideae with a clade consisting of the monophyletic Sporadanthoideae and Leptocarpoideae nested within them. The Bromeliaceae phylogeny obtained from Topo6 is insufficiently sampled to make reliable statements, but indicates a good starting point for further investigations.

INFERENCES ABOUT PHYLOGENY AND SOUTH AMERICAN–AFRICAN DISJUNCTIONS IN RAPATEACEAE AND BROMELIACEAE BASED ON ndhF SEQUENCE DATA Thomas J. Givnish,1,* Kendra C. Millam,* Timothy M. Evans,y Jocelyn C. Hall,* J. Chris Pires,* Paul E. Berry,* and Kenneth J. Sytsma* *Department of Botany, University of Wisconsin, Madison, Wisconsin 53706, U.S.A.; and yDepartment of Botany, Hope College, Holland, Michigan 49428, U.S.A. Rapateaceae and Bromeliaceae each have a center of diversity in South America and a single species native to a sandstone area in west Africa that abutted the Guayana Shield in northern South America before the Atlantic rifted. They thus provide ideal material for examining the potential role of vicariance versus long-distance dispersal in creating amphiatlantic disjunctions. Analyses based on ndhF sequence variation indicate that Rapateaceae and Bromeliaceae are each monophyletic and underwent crown radiation around 41 and 23 Ma, respectively. Both exhibit clocklike sequence evolution, with bromeliads evolving roughly one-third more slowly than rapateads. Among rapateads, the divergence of west African Maschalocephalus dinklagei from its closest South American relatives implies that Maschalocephalus resulted via long-distance dispersal 7 Ma, not ancient continental drift; only its sandstone habitat is vicariant. Rapateads arose first at low elevations in the Guayana Shield; the earliest divergent genera are widespread along riverine corridors there and, to a lesser extent, in Amazonia and the Brazilian Shield.
