  • Aerangis Articulata by Brenda Oviatt and Bill Nerison an Exquisite Star from Madagascar
    COLLECTor’s item by Brenda Oviatt and Bill Nerison Aerangis articulata An Exquisite Star from Madagascar IN ALL HONESTY, WHEN WE FOUND out that our photo of Aerangis articulata was chosen for the cover of Isobyl la Croix’s (2014) new book Aerangis, we were more than just a little excited! We decided that this is a perfect opportunity to tell people more about Aergs. articulata and give an introduction to her new book. We will try and help clarify the confusion surrounding the identification of this species, describe what to look for if you intend to buy one and discuss culture to help you grow and bloom it well. We love angraecoids, and the feature that most share and what sets them apart is their spurs or nectaries. In some orchid species, attracting the pollinator is all about fooling someone (quite often an insect). Some will mimic a female insect while others will mimic another type of flower to attract that flower’s pollinator. Oftentimes the u n s u s p e c t i n g insect gets nothing in return; not the promised mate or the nectar of the Brenda Oviatt and mimicked flower. Bill Nerison With angraecoids, the pollinator is often rewarded with a sweet treat: nectar that sits in the bottom of the spur. The pollinator of Aergs. articulata is a hawk moth (DuPuy, et al 1999) whose proboscis can reach that nectar. These moths are attracted by the sweet nighttime fragrance TT (scented much like a gardenia) and by the A VI O white flower (more visible than a colored A D flower in the dark).

  • Ants Tend Ghost Orchids: Patrolling of Dendrophylax Lindenii (Orchidaceae) by Crematogaster Ashmeadi in Florida
    Ants tend ghost orchids: patrolling of Dendrophylax lindenii (Orchidaceae) by Crematogaster ashmeadi in Florida Peter R. Houlihan1,5,*, Andrea Lucky2, Mike Owen3, and Thomas C. Emmel1,2,4,6 Abstract Myriad symbioses exist between insects and orchids, especially in tropical forests where the majority of species are epiphytic. Relationships be- tween ants and rare epiphytic orchids are underrepresented in the scientific literature. The natural history and ecological entomology of Florida’s endangered and epiphytic ghost orchid, Dendrophylax lindenii (Lindley) Bentham ex Rolfe (Orchidaceae), remain limited. Widely recognized for long-standing hypotheses concerning the species’ pollination ecology, that documentation recently overturned, other interactions between insects and ghost orchids are scarce. Here we describe the first associations between ants, Crematogaster ashmeadi Mayr (Hymenoptera: For- micidae), and D. lindenii. Ghost orchid roots provide facultative and opportunistic structures for arboreal ants to use in nesting. Furthermore, excrement from ant colonies within the root mass can increase nutrient availability in the orchid’s nutrient-poor substrate; the proximity of these ants permits patrolling to defend the plant and exert control over possible extra floral nectaries that require further inquiry. This study presents novel observations that expand the known insect associations with ghost orchids, elucidating the complex ecology of one of Florida’s rarest and most endangered species. Key Words: ants; arboreal; ecology; epiphyte; Everglades; Fakahatchee Resumen Existen incontables números de simbiosis entre insectos y orquídeas, especialmente en los bosques tropicales donde la mayoría de las especies son epífitas. Las relaciones entre las hormigas y las orquídeas epífitas más raras están subrepresentadas en la literatura científica.

  • Lankesteriana 1
    LANKESTERIANA 4(1): 47-56. 2004. NOTES ON THE CARIBBEAN ORCHID FLORA. V. NEW SPECIES, COMBINATIONS AND RECORDS JAMES D. ACKERMAN Department of Biology, University of Puerto Rico, PO Box 23360 San Juan, PR 00931-3360, USA [email protected] ABSTRACT. Three species of Orchidaceae are described as new to science: a Telipogon and a Lankesterella from the Dominican Republic and an Encyclia from Cuba. Telipogon niri is based on material collected by Donald Dod from the Cordillera Central A rare species, T. niri was previously recognized as Stellilabium minutiflorum (Kraenzl.) Garay, a distinct species from Central America. The generic name has changed due to unequivocal molecular evidence offered by Norris Williams, and the specific epithet honors Dr. Mark Nir, an avid student of Caribbean orchids. Lankesterella glandula is also based on material collected by Dod from the Cordillera Central. Thus far known only from the type collection, it is the second representative of the genus in Hispaniola. Encyclia monteverdensis is described from 19th century Charles Wright collections from Monte Verde, Cuba. The combination, Dendrophylax filiformis (Sw.) Carlsward & Whitten, suffers as a later homonym and is replaced by the next available name in the new combination Dendrophylax mon- teverdi (Rchb. f.) Ackerman & Nir. Cyclopogon miradorensis Schltr. is reported for the island of Dominica; Cranichis ricartii Ackerman is noted for the island of Guadeloupe; Cranichis ovata Wickstr. and Psilochilus macrophyllus (Lindl.) Ames are noted for Montserrat; and Trinidad is another locality for C. ovata. In addi- tion, Eurystyles domingensis Dod and two Malaxis species are added to the Cuban flora: M.

  • Cytotaxonomy of the Monopodial Orchids of the African and Malagasy Regions
    Cytotaxonomy of the monopodial orchids of the African and Malagasy regions J. C. Arends & F. M. Van der Laan Department of Plant Taxonomy and Plant Geography, Agricultural University, Gen. Foulkesweg 37, 6700 ED Wageningen, The Netherlands Abstract The three subtribes which are recognized within the tribe Vandeae are represented in the tropical African and Malagasy regions. All taxa of the Vandeae have a monopodial growth habit. The first subtribe, Sarcanthinae, is mainly Asian-Australasian, but a few of its species occur in Madagascar and in Africa. The other two subtribes, Angraecinae and Aerangidinae, are both represented in the latter two regions. The Angraecinae ischaracterize d by the presence of a short rostellum, but this iselongate d in the Aerangidinae. According to earlier authors there is a correlation between presence of the short rostellum and a basic chromosome number of x= 19i nth e Angraecinae, and between the presence of an elongated rostellum and a basic number of x = 25 in the Aerangidinae. The results presented in this paper are placed in perspective with the chromosome numbers recorded by other authors. From the resulting chromosome number survey it appears that only part of the Angraecinae (Aeranthes, several species of Angraecum. Cryptopus and Jumellea) have a basic number of x = 19; some members of the Angraecinae (other species of Angraecum) were found to have a basic number of x = 21,24 and 25. The Aerangidinae is not characterized by a single basic number of x= 25 but by aserie s ranging from x = 23t o x= 27,o f which x= 23,24 and 25ar e the most frequent.

    COLLECTor’s item Aerangis hariotiana by Brenda Oviatt and Bill Nerison Photgraphs and drawing by Brenda Oviatt The Aerangis Formerly Known as ... Aerangis hariotiana can produce a plethora of long-lasting, brightly colored flowers. Grower: Botanica Ltd. 590 ORCHIDS AUGUST 2016 WWW.AOS.ORG WHAT’S IN A name? This plant is better known by its former name; Microterangis hariotiana or even Chamaeangis hariotiana. Prior to that, it was also called Saccolabium hariotianum, and was first described in 1897 as Mystacidium hariotianum. Names aside, this is a charming, floriferous, colorful semiminiature orchid and we are excited to write about it; it’s a rewarding orchid to grow. Our specimen was beginning to bloom and we were sure we could get some excellent photos of this extraordinary plant. Mature, multigrowth plants will produce many spikes and are very long-lasting (read the culture section to find out why no such photo is included in this article). We began doing research about the history of the species and found that confusion seems to be prevalent with regard to it, especially on the Internet. We decided to look at the plant from a different angle for this article. First, some back- ground. The ge- nus Chamaeangis was established by Rudolf Schlechter in 1915 and, even at that point, he divided it into two Brenda Oviatt and sections based on Bill Nerison differences in the flower structure: Chamaeangis and Microterangis. He noted that there were enough differences between the sections that section 1 Microterangis might be elevated to genus level at some point (which was done in now called Diaphananthe odoratissima.

Note the pollinia attached to the base of JAMES PETRANKA JAMES the skipper’s proboscis. bumblebee species. In this case, pollinia of Den. infundibulum are placed on the head of the bee while that from the Cymbidium, with much longer column, becomes at- tached to the bee’s central thorax. Because the column of the former species is much shorter, only pollinia placed near the front of the bee will be in a position to contact the stigmatic surface of the Dendrobium column as the bee exits the flower (Du Puy and Cribb 2007). Orchids with large gullet flowers such as Cymbidium are typically pollinated by large carpenter bees and bumblebees are known to pollinate Spiranthes and are implicated in the pollination of northern NT NT U U and some high-elevation species where other large bees are less common or active. 3 4 ERIC H ERIC H Some bees gather oils from flowers rather than nectar or pollen and many orchids [3–4] Sobralia [3] and Cattleya [4], two gen- NO ONE IS REALLY SURE HOW LONG have evolved to attract these pollinators.
