Were Largely Copied from Rolfe, Adding Nothing Unsatisfacto Monograph of the tribe Apostasieae (Orchidaceae) E.F. de Vogel Summary This paper embraces a full taxonomic revision of the tribe Apostasieae. is The introduction followed by an ample discussion of the taxonomic position of the Apostasieae and the affinities within the tribe. The tribes Apostasieae and Cypripedieae are regarded as forming together the subfamily Cypripedioideae of the Orchidaceae. Notes is are given on the morphology and an evaluation given on systematic characters and their value for specific delimitation. Two characters were formerly underestimated in Neuwiedia, notably the indument (maximal length of the glandless hairs) and the structure (texture) of the pericarp. The systematic treatment provides descriptions of the tribe, the genera, and the species, keys for identification,full synonymy, typification, geographicaldistribution,and an index to specimens examined. The from the the Louisiades and Apostasieae range Ceylon to Ryukyus through to North Queensland. Ranges are drawn on maps. Two genera are distinguished, Apostasia and Neuwiedia; Adactylus is reduced to sectional status under Apostasia. In Neuwiedia 8 species are distinguished among which 4 are new, viz. 3 from Borneo and I from Siam. Under N. zollingeri, 2 varieties are recognized besides the type variety, both based on former species, viz. de and de One is var. javanica (J.J.S.)

The first written Rolfe who besides monograph was by (1889) gave, an enumeration remarks of species, general on their morphology and distribution. Taking into consider- ation the material Rolfe had at his disposal, his work was very satisfactory indeed. He to have had clear vision of the characters within the proves a important systematic group. Rolfe had with the several However, to cope difficulty that species were based on in- complete material by which essential characters remained sometimes unknown. Unfortunately, the two later monographs, by Kraenzlin (1897) and Pfitzer (1903) were largely copied from Rolfe, adding nothing new save a unsatisfactory key, but failed to add a study of the additional material collected in the preceding two decades. Since blurred that timetwo factors have the systematics of the group. First, considerable confusion caused authors of several Floras who the older was by misinterpreted species. for Second, the same cause, some later orchidologists described new species without careful them with material. their sometimes made checking type Also, descriptions were from buds and in general they attached too much value to size in describing new taxa. 314 BLUMEA VOL.

Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

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.

  • Triphora Trianthophora (Swartz) Rydb. Three-Birds Orchid
    New England Plant Conservation Program Conservation and Research Plan Triphora trianthophora (Swartz) Rydb. Three-birds Orchid Prepared by: Jennifer M. Ramstetter Professor of Biology Marlboro College For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, May 2001 SUMMARY Triphora trianthophora (Swartz) Rydberg (Ochidaceae), three-birds orchid or nodding pogonia, is represented by 24 current occurrences in New England. Triphora trianthophora is protected as a threatened (T) or endangered (E) species in Maine (T), Vermont (T), New Hampshire (T), and Massachusetts (E); it is thought to be extirpated in Connecticut. It is a Division 2a plant species according to the Flora Conservanda: New England of the New England Plant Conservation Program. There are also several undocumented occurrences in New Hampshire. Recent fieldwork indicates that three of the occurrences may be extirpated, and only ten occurrences had greater than 100 stems at the most recent survey. Current occurrences represent about half of all known current and historic occurrences. The orchid is also rare and threatened in much of its range in North America; it is an S1 or S2 species in 19 of the 30 states in which it occurs and in Ontario. In New England, the orchid typically occurs in moist hardwood forests dominated by beech in conditions of filtered light. Plants frequently grow in hollows filled with deep leaf litter with few or no other herbaceous plant species co-occurring. Triphora trianthophora is thought to depend upon mycorrhizal relationships and to act as a semi-saprophyte.

  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

Box 230, Sabinda, Queensland 4861 Phone: 070 671 i77 Our Wet season started off with a bang and we had 64 inches of rain in the 16 days that followed Christmas. After that the sun re- appeared and we've since sweltered in a lowland tropical heat bath with sunshine every day and no rain. How the plants cope with such wild swings in their environment is one of Nature's miracles, but the native orchids seem to take it all in their stride. Our regular correspondent, Mary Gandini of Cairns, wrote to us on 11th December: I've had lots of lovely flowers this year, probably because they did get the occasional. dose of fertiliser. The piece de resistance a fortnight ago was the first flowering of Dendrobium wassellij with three sprays of fl-owers - typical pencil orchid style. The new plant list from the Queensland Herbarium now names all of the pencil-type orchids Dockrillia so your Dendrobium teretifolium is now Dockrillia teretifolia. Strangely though they have left wassellii as Dendrobium. Also they seem to have accepted most of David Jones' splitters that he named in his book, e.g., Dendrobirlm cap.i tis-york. I have observed a spray of potential flowers emerging from my Vanda hindsii. The first time - exciting! D. kingianum did nothing this year. D. j0nesi.i did well as did D. bifa1ce. I had some lovely flowers on Pterostylis baptisti and they set seed but I missed directing it to where I wanted it.
