ANPS(A) INDIGENOUS ORCHID STUDY GROUP ISSN 1036-9651 Group Leaders: Don and Pauline Lawie P.O. Bos 230. BABINDA 4861 Phone: 0740 671 577 News1 etter 7 1 June 2010 I was going to commence this newsletter with apologies to anyone whose photographs were not up to scratch and blame the printer. However, a little more experimentation revealed operator ignorance. The error of having the first page of Newsletter 70, declaring it was Newsletter 69 and dated December 2009, while the other pages are headed correctly, can only be explained by lack of attention to detail by the typist. Yes, that was me and I do apologise.. I also failed to enclose receipts where they were due. More apologies. "Pauline must pay more attention to her home work" C 1950. Eleanor Handreck, Study Groups Liaison Officer for APS, South Australia Region, commented in her report on our newsletter 69: "Why an Oz orchid should have the specific epithet 'sinensis' (Chinese, or from China) is beyond me!" Incase it has occurred to anyoile else to wu~ide~."This widespread species extends from India- to Australia and New Zealand, as far north as China, Japan and Siberia" says BotanicaJAs.Pocket Orchids. The taxonomic convention decrees that the first name given to a plant is THE name, so that if the same plant is found and named elsewhere, when a previous recording is uncovered the new name is changed to the original. As Australia is in the New World it has happened quite a bit to us and it seems a pity that the specific name of some of our orchids no longer honours people we know who made such wonderhl "discoveries". -
Typification of Infrageneric Taxa in Dendrobium(Orchidaceae)
Typification of infrageneric taxa in Dendrobium (Orchidaceae) André Schuiteman Royal Botanic Gardens, Kew, Richmond, Surrey, TW9 3AB, United Kingdom; e-mail: [email protected] Introduction Abstract The nomenclature of infrageneric taxa in Orchidaceae on occasion In order to stabilise the nomenclature borders on the chaotic. In the past, names were often proposed in a of infrageneric taxa in Dendrobium, type species are chosen for those highly informal fashion, with little concern for typification, priority, taxa for which this has not been precise circumscription, or even ranking. Such names were frequently done previously. In all, 35 names are applied to sets of species which had little in common beyond one or typified, including one genus name a few key characters. Those who used these names rarely cited their (Onychium), and assigned to sections authors, while the circumscription of the taxa often varied considerably of Dendrobium as recognised in Genera Orchidacearum. from one botanist to the next. It was not uncommon that earlier names were deliberately disregarded, to be replaced with new names that Keywords: Dendrobium, infrageneric taxa, nomenclature, taxonomy more or less covered the same groups. As a result, the nomenclature and systematics of many infrageneric taxa were, and sometimes still are, Muelleria 30(1): 3–7 (2012) extremely confused. In Dendrobium, one of the largest orchid genera with some 1500 species (Pridgeon et al., in prep.), well over 200 subgenera, sections and subsections have been proposed. Examples of all the problems just mentioned can be found in abundance in this gargantuan taxon. Fortunately, many of these problems can be solved rather easily by carefully typifying the taxa involved. -

Blume f. conformis Hi- ros. Hayak. et J. Yokoy., which occurs in the vicinity of the Tsukuba mountain range in Ibaraki Prefec- ture, Japan. This peloric form is sympatric with C. falcata f. falcata. The peloric flowers have a petal-like lip. The flowers are radially symmetrical and the perianth parts spread weakly compared to normal flow- ers. The stigmas are positioned at the column apex, thus neighboring stigmas and the lower parts of the pollinia are conglutinated. We observed similar vegetative traits among C. falcata f. falcata, C. falcata f. albescens S. Kobayashi, and C. falcata f. conformis. The floral morphology in C. falcata f. conformis resembles that of C. nanchuanica (S.C. Chen) X.H. Jin et X.G. Xiang (i.e., similar petal-like lip and stig- ma position at the column apex; syn.

THE SCIENCE OF BOTANICAL ART Orchids By Dick Rauh Originally appeared in The Botanical Artist, Volume 13, Issue 3 Orchids are one of the largest and most diverse families in flowering plants. Many genera have adapted to very specific pollinators and so have evolved very different forms. So the important question arises as to which of their characteristics can be called up to give them an identity as a group. What can we look to, to be able to spot a plant as modest as a rattlesnake plantain, and find a cousin in a huge, showy Cattleya and know that they are closely related? First of all, orchids are monocots. This means they are kin to lilies, tulips and grasses, and some of their strongest identifying features are ones they have in common with this large group of plants. I speak of parts in threes, stalkless leaves with parallel venation, a herbaceous habit, and adventitious roots. The flowers of orchids, like many monocots have sepals and petals that are alike in appearance, primarily in the fact that both are petal-like with a wide range of color and pattern. The three sepals and two of the petals are also often very similar in form. However the median of the three petals in orchids, really takes off. It is known as the labellum or lip, and its intricate and diverse forms are one of the reasons orchids provide such constant excitement. If the flower were to grow normally this lip would be at the top of the bloom, but orchids are what is known as resupinate. -

E-mail: [email protected] The main phytogeographic regions within the eastern part of the Indochinese Peninsula are delimited on the basis of analysis of recent literature on geology, geomorphology and climatology of the region, as well as numerous recent literature information on phytogeography, flora and vegetation. The following six phytogeographic regions (at the rank of floristic province) are distinguished and outlined within eastern Indochina: Sikang-Yunnan Province, South Chinese Province, North Indochinese Province, Central Annamese Province, South Annamese Province and South Indochinese Province. Short descriptions of these floristic units are given along with analysis of their floristic relationships. Special floristic analysis and consideration are given to the Orchidaceae as the largest well-studied representative of the Indochinese flora. 1.

A History of Orchids. a History of Discovery, Lust and Wealth

A HISTORY OF DISCOVERY, LUST AND WEALTH Nora Eugenia D. G. ANGHELESCU1, Annie BYGRAVE2, Mihaela I. GEORGESCU1, Sorina A. PETRA1, Florin TOMA1 1University of Agronomic Sciences and Veterinary Medicine of Bucharest, 59 Mărăști Blvd, District 1, Bucharest, Romania 2Self-employed, London, UK Corresponding author email: [email protected] Abstract Orchidaceae is the second largest families of flowering plants. There are approximately 900 orchid genera comprising between 28,000-32,000 species of orchids. The relationship between orchids and mankind is complex. The history of orchids’ discovery goes hand in hand with the history of humanity, encompassing discovery and adventure, witchcraft and magic, symbolism and occultism, addiction and sacrifice, lust and wealth. Historically, the Chinese were the first to cultivate orchids as medicinal plants, more than 4000 years ago. Gradually, records about orchids spread, reaching the Middle East and Europe. Around 300 B.C., Theophrastus named them for the first time orkhis. In 1737, Carl Linnaeus first used the word Orchidaceae to designate plants with similar features. The family name, Orchidaceae was fully established in 1789, by Antoine Laurent de Jussieu. In 1862, Charles Darwin published the first edition of his book, Fertilisation of Orchids. Darwin considered the adaptations of orchid flowers to their animal pollinators as being among the best examples of his idea of evolution through natural selection. Orchidology was on its way. During the 18th and the 19th centuries, orchids generated the notorious Orchid Fever where orchid-hunters turned the search for orchids into a frantic and obsessive hunt. -
BIODIVERSITY CONSERVATION on the TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and Plants
BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands. -

Phylogeny, Character Evolution and the Systematics of Psilochilus (Triphoreae)
THE PRIMITIVE EPIDENDROIDEAE (ORCHIDACEAE): PHYLOGENY, CHARACTER EVOLUTION AND THE SYSTEMATICS OF PSILOCHILUS (TRIPHOREAE) A Dissertation Presented in Partial Fulfillment of the Requirements for The Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Erik Paul Rothacker, M.Sc. ***** The Ohio State University 2007 Doctoral Dissertation Committee: Approved by Dr. John V. Freudenstein, Adviser Dr. John Wenzel ________________________________ Dr. Andrea Wolfe Adviser Evolution, Ecology and Organismal Biology Graduate Program COPYRIGHT ERIK PAUL ROTHACKER 2007 ABSTRACT Considering the significance of the basal Epidendroideae in understanding patterns of morphological evolution within the subfamily, it is surprising that no fully resolved hypothesis of historical relationships has been presented for these orchids. This is the first study to improve both taxon and character sampling. The phylogenetic study of the basal Epidendroideae consisted of two components, molecular and morphological. A molecular phylogeny using three loci representing each of the plant genomes including gap characters is presented for the basal Epidendroideae. Here we find Neottieae sister to Palmorchis at the base of the Epidendroideae, followed by Triphoreae. Tropidieae and Sobralieae form a clade, however the relationship between these, Nervilieae and the advanced Epidendroids has not been resolved. A morphological matrix of 40 taxa and 30 characters was constructed and a phylogenetic analysis was performed. The results support many of the traditional views of tribal composition, but do not fully resolve relationships among many of the tribes. A robust hypothesis of relationships is presented based on the results of a total evidence analysis using three molecular loci, gap characters and morphology. Palmorchis is placed at the base of the tree, sister to Neottieae, followed successively by Triphoreae sister to Epipogium, then Sobralieae.
