FROM THE EDITORS. We would like to start this issue with an apology for its late arrival to you. Unfortunately, we experienced an unexpected delay in the arrival of replacment parts for the copying equipment. The good news this issue is of course that spring is upon us again, and with it the regrowth of our dormant varieties ready to come forward and show off their beauty for yet another year. The response for articles for the newsletter is dissappointing to say the least. There is enough experienced c.p. growers in Australia capable of contributing write-ups to ensure the success of the CPNA for many years to come, but if the lack of interest continues the newsletter is doomed to failure. To put it bluntly, if you want your newsletter to continue then get behind it and give it your support.

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. -
Floral Micromorphology and Nectar Composition of the Early Evolutionary Lineage Utricularia (Subgenus Polypompholyx, Lentibulariaceae)
Protoplasma https://doi.org/10.1007/s00709-019-01401-2 ORIGINAL ARTICLE Floral micromorphology and nectar composition of the early evolutionary lineage Utricularia (subgenus Polypompholyx, Lentibulariaceae) Bartosz J. Płachno1 & Małgorzata Stpiczyńska 2 & Piotr Świątek3 & Hans Lambers4 & Gregory R. Cawthray4 & Francis J. Nge5 & Saura R. Silva6 & Vitor F. O. Miranda6 Received: 1 April 2019 /Accepted: 4 June 2019 # The Author(s) 2019 Abstract Utricularia (Lentibulariaceae) is a genus comprising around 240 species of herbaceous, carnivorous plants. Utricularia is usually viewed as an insect-pollinated genus, with the exception of a few bird-pollinated species. The bladderworts Utricularia multifida and U. tenella are interesting species because they represent an early evolutionary Utricularia branch and have some unusual morphological characters in their traps and calyx. Thus, our aims were to (i) determine whether the nectar sugar concentrations andcompositioninU. multifida and U. tenella are similar to those of other Utricularia species from the subgenera Polypompholyx and Utricularia, (ii) compare the nectary structure of U. multifida and U. tenella with those of other Utricularia species, and (iii) determine whether U. multifida and U. tenella use some of their floral trichomes as an alternative food reward for pollinators. We used light microscopy, histochemistry, and scanning and transmission electron microscopy to address those aims. The concentration and composition of nectar sugars were analysed using high-performance liquid chroma- tography. In all of the examined species, the floral nectary consisted of a spur bearing glandular trichomes. The spur produced and stored the nectar. We detected hexose-dominated (fructose + glucose) nectar in U. multifida and U. tenella as well as in U. -
Brocchinia Reducta Light Preferences
BROCCHINIA REDUCTA LIGHT PREFERENCES BARRY RICE • P.O. Box 72741 • Davis, CA 95617 • USA • [email protected] Keywords: cultivation: Brocchinia reducta, lighting. Brocchinia reducta is one of those species of plants that has, at best, mixed support by carnivorous plant growers. The plant’s problem is that it is usually relegated to the ranks of semi- carnivory, or even noncarnivory. This is because it apparently does not produce its own digestive enzymes, nor does it seem particularly specialized for capturing insects. In fact, most photographs of the plant in cultivation show that it looks like a fairly unimpressive, urn-shaped bromeliad (see Figures 1, 2). I have grown this plant for nearly a decade, and agree that in most settings it is indeed a rather boring bromeliad. I do not even maintain plants in my own collection, instead I grow the plants at the University of California (Davis) collections. It is trivial to grow—it does not seem to care too much about the soil medium, and keeping it in a 1:1:1 sand:perlite:peat mix or 3:1 perlite:sphagnum mix and temperatures anywhere in the range 15-35ºC (60-95ºF) works just fine. I provide the plants with purified water, which I pour directly into the pitcher urn. I do not fertilize them. Typically a plant matures within a few years, produces an inflorescence, and then dies. As it rots away, two or more new shoots emerge from the plant—these are called pups by bromeli- ad growers—and they can be separated when the parent plant rots away. -

As with other groups of plants, wide array of ecological and evolutionary questions. Now that reliable such as mangroves7 and alpine plants8 that exhibit molecular phylogenies are available for many carnivorous plants, they can be broad evolutionary convergence because of strong used to study convergences and divergences in ecophysiology and life-history selection in stressful habitats, detailed investigations strategies. Cost–benefit models and demographic analysis can provide insight of carnivorous plants at multiple biological scales can into the selective forces promoting carnivory. Important areas for future illustrate clearly the importance of ecological research include the assessment of the interaction between nutrient processes in determining evolutionary patterns. availability and drought tolerance among carnivorous plants, as well as measurements of spatial and temporal variability in microhabitat Phylogenetic diversity among carnivorous plants characteristics that might constrain plant growth and fitness. In addition to Phylogenetic relationships among carnivorous plants addressing evolutionary convergence, such studies must take into account have been obscured by reliance on morphological the evolutionary diversity of carnivorous plants and their wide variety of life characters1 that show a high degree of similarity and forms and habitats. Finally, carnivorous plants have suffered from historical evolutionary convergence among carnivorous taxa9 overcollection, and their habitats are vanishing rapidly. -
PHYLOGENY, ADAPTIVE RADIATION, and HISTORICAL BIOGEOGRAPHY of BROMELIACEAE INFERRED from Ndhf SEQUENCE DATA
Aliso 23, pp. 3–26 ᭧ 2007, Rancho Santa Ana Botanic Garden PHYLOGENY, ADAPTIVE RADIATION, AND HISTORICAL BIOGEOGRAPHY OF BROMELIACEAE INFERRED FROM ndhF SEQUENCE DATA THOMAS J. GIVNISH,1 KENDRA C. MILLAM,PAUL E. BERRY, AND KENNETH J. SYTSMA Department of Botany, University of Wisconsin, Madison, Wisconsin 53706, USA 1Corresponding author ([email protected]) ABSTRACT Cladistic analysis of ndhF sequences identifies eight major bromeliad clades arranged in ladderlike fashion. The traditional subfamilies Tillandsioideae and Bromelioideae are monophyletic, but Pitcair- nioideae are paraphyletic, requiring the description of four new subfamilies, recircumscription of Pit- cairnioideae and Navioideae, the sinking of Ayensua, and description of the new genus Sequencia. Brocchinioideae are basalmost, followed by Lindmanioideae, both restricted to the Guayana Shield. Next is an unresolved trichotomy involving Hechtioideae from Central America, Tillandsioideae, and the remaining bromeliads in subfamilies Navioideae, Pitcairnioideae, Puyoideae, and Bromelioideae. Bromeliads arose as C3 terrestrial plants on moist infertile sites in the Guayana Shield roughly 70 Mya, spread centripetally in the New World, and reached tropical West Africa (Pitcairnia feliciana) via long-distance dispersal about 10 Mya. Modern lineages began to diverge from each other 19 Mya and invaded drier areas in Central and South America beginning 15 Mya, coincident with a major adaptive radiation involving the repeated evolution of epiphytism, CAM photosynthesis, impounding leaves, several features of leaf/trichome anatomy, and accelerated diversification at the generic level. This ‘‘bromeliad revolution’’ occurred after the uplift of the northern Andes and shift of the Amazon to its present course. Epiphytism may have accelerated speciation by increasing ability to colonize along the length of the Andes, while favoring the occupation of a cloud-forest landscape frequently dissected by drier valleys. -
Hydrophobic Trichome Layers and Epicuticular Wax Powders in Bromeliaceae1
American Journal of Botany 88(8): 1371±1389. 2001. HYDROPHOBIC TRICHOME LAYERS AND EPICUTICULAR WAX POWDERS IN BROMELIACEAE1 SIMON PIERCE,2,3 KATE MAXWELL,2 HOWARD GRIFFITHS,2 AND KLAUS WINTER Smithsonian Tropical Research Institute, Apartado 2072, Balboa, Panama City, Republic of Panama The distinctive foliar trichome of Bromeliaceae has promoted the evolution of an epiphytic habit in certain taxa by allowing the shoot to assume a signi®cant role in the uptake of water and mineral nutrients. Despite the profound ecophysiological and taxonomic importance of this epidermal structure, the functions of nonabsorbent trichomes in remaining Bromeliaceae are not fully understood. The hypothesis that light re¯ection from these trichome layers provides photoprotection was not supported by spectroradiometry and ¯uorimetry in the present study; the mean re¯ectance of visible light from trichome layers did not exceed 6.4% on the adaxial surfaces of species representing a range of ecophysiological types nor was signi®cant photoprotection provided by their presence. Several reports suggesting water repellency in some terrestrial Bromeliaceae were investigated. Scanning electron microscopy (SEM) and a new techniqueЯuorographic dimensional imaging (FDI)Ðwere used to assess the interaction between aqueous droplets and the leaf surfaces of 86 species from 25 genera. In the majority of cases a dense layer of overlapping, stellate or peltate trichomes held water off the leaf epidermis proper. In the case of hydrophobic tank-forming tillandsioideae, a powdery epicuticular wax layer provided water repellency. The irregular architecture of these indumenta resulted in relatively little contact with water droplets. Most mesic terrestrial Pitcairnioideae examined either possessed glabrous leaf blades or hydrophobic layers of con¯uent trichomes on the abaxial surface. -

KEY to the GENERA of BROMELIACEAE at 9/2019 by Derek Butcher
KEY TO THE GENERA OF BROMELIACEAE at 9/2019 by Derek Butcher This follows roughly the information given in the Monograph by Smith and Downs (Flora Neotropica no. 14, 1974 - 77) which covered 46 genera. This was expanded in Lyman Smith’s paper in Beitr. Biol. Pflanzen 63 (1988) 403 - 411 to cover 51 genera where he added new genera Steyerbromelia, Brewcaria, Pseudaechmea, and Lymania. Lindmania was revived from synonymy of Cottendorfia. In the same issue but on pages 101 - 113 Elvira Gross reported findings on the germination processes of the three subfamilies and one facet is shown in the key below. The key was further updated in 1998 by L B Smith and W Till to cover 56 genera in The Families and Genera of Vascular plants, Kubitzki pages 83 - 86 (1998) where Alcantarea, Werauhia, Ursulaea, Pepinia, and Racinaea were added. Abromeitiella had been placed in synonymy under Deuterocohnia Note that Streptocalyx was retained purely because the genus Aechmea is currently in a state of flux. From a horticultural point of view the retention of this genus tends to make sense because of the similar growing conditions needed to get good specimens. However, Chevaliera was resurrected to genus status because of its clearly delineated boundaries and is said to be more of a natural group. Since this publication the genera have increased to 58 where Derek Butcher has now added Canistropsis, and Edmundoa, and made adjustments to Canistrum, Nidularium, and Wittrockia because of Elton Leme’s recent work Canistrum - Bromeliads of the Atlantic Forest (1997) and Canistropsis - Bromeliads of the Atlantic Forest (1998). -
Flower Nectar Trichome Structure of Carnivorous Plants from the Genus Butterworts Pinguicula L

(Lentibulariaceae) Krzysztof Lustofin1 & Piotr Świątek2 & Vitor F. O. Miranda3 & Bartosz J. Płachno1 Received: 23 June 2019 /Accepted: 7 August 2019 /Published online: 19 August 2019 # The Author(s) 2019 Abstract Pinguicula (Lentibulariaceae) is a genus comprising around 96 species of herbaceous, carnivorous plants, which are extremely diverse in flower size, colour and spur length and structure as well as pollination strategy. In Pinguicula,nectarisformedinthe flower spur; however, there is a gap in the knowledge about the nectary trichome structure in this genus. Our aim was to compare the nectary trichome structure of various Pinguicula species in order to determine whether there are any differences among the species in this genus. The taxa that were sampled were Pinguicula moctezumae, P. moranensis, P. re ct if ol ia, P. emarginata and P. esseriana. We used light microscopy, histochemistry, scanning and transmission electron microscopy to address those aims. We show a conservative nectary trichome structure and spur anatomy in various Mexican Pinguicula species. The gross structural similarities between the examined species were the spur anatomy, the occurrence of papillae, the architecture of the nectary trichomes and the ultrastructure characters of the trichome cells. However, there were some differences in the spur length, the size of spur trichomes, the occurrence of starch grains in the spur parenchyma and the occurrence of cell wall ingrowths in the terminal cells of the nectary trichomes. Similar nectary capitate trichomes, as are described here, were recorded in the spurs of species from other Lentibulariaceae genera.
