Activities such as amenity forests, camping sites and outdoor sports can cause destruction to natural habitat. Geologically, the formation involved granites as the core and quartzite covers the outer layer of the mountain. This indicates the establishment of hill heath forest vegetation, mostly on the summit region and lowland dipterocarp forest vegetation at lower region. The uniqueness of its vegetation attracts botanists and collectors to do series of plant collection since 1845.

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.

Gardens’ Bulletin Singapore 67(1): 107–122. 2015 107 doi: 10.3850/S2382581215000125 New orchid records for Myanmar, including the first record of the genus Stereosandra H. Kurzweil1 & Saw Lwin2 1Herbarium, Singapore Botanic Gardens, National Parks Board, 1 Cluny Road, Singapore 259569 [email protected] 2Myanmar Floriculturist Association, Yangon, Myanmar [email protected] ABSTRACT. Nine orchid species, Bulbophyllum capnophyton J.J.Verm. et al., Dendrobium macrostachyum Lindl., D. praecinctum Rchb.f., Habenaria reniformis (D.Don) Hook.f., Liparis distans C.B.Clarke, L. resupinata Ridl., Micropera thailandica (Seidenf. & Smitinand) Garay, Oberonia obcordata Lindl. and Stereosandra javanica Blume, are reported as new for Myanmar. Of particular interest is the Stereosandra as it is the first record of this genus in the country. Keywords. Myanmar, Orchidaceae, new distribution records Introduction The orchid flora of Myanmar is very rich but as yet poorly known (a brief overview of the current state of orchid floristics in the country is given in Ormerod & Sathish Kumar, 2003, 2008), and a complete inventory of all species of Orchidaceae found in the country is not yet available. Our ongoing studies resulted in nine additions to the orchid flora of Myanmar, namely Bulbophyllum capnophyton J.J.Verm. et al. (syn. Trias nana Seidenf.), Dendrobium macrostachyum Lindl., D. praecinctum Rchb.f., Habenaria reniformis (D.Don) Hook.f., Liparis distans C.B.Clarke, L. resupinata Ridl., Micropera thailandica (Seidenf. & Smitinand) Garay, Oberonia obcordata Lindl. and Stereosandra javanica Blume, all of which are new records for Myanmar of species found in adjacent countries. Stereosandra is recorded from Myanmar for the first time.

Nuraliev, Andrey N. Kuznetsov, Svetlana P. Kuznetsova & Leonid V. Averyanov Summary: The paper summarizes results of investigations of non-green plants carried out in the Russian-Vietnamese Tropical Center during the years 2009 –2018. The checklist is provided which includes 29 species in seven families. Among them, holoparasites are represented only by the family Balanophoraceae (4 spp.), while the mycoheterotrophs comprise Ericaceae (1 sp.), Petrosaviaceae (1 sp.), Orchidaceae (16 spp.), Burmanniaceae (1 sp.), Thismiaceae (3 spp.) and Triuridaceae (4 spp.). Four species new to science and several new species records for Vietnam were published during this study. The highest diversity of non-photosynthetic plants was found in Central Highlands and especially in Thach Nham protected forest and Chu Yang Sin National Park. The obtained specimens are currently employed in morphological, phylogenetic and genomic studies of several groups of heterotrophic plants. Keywords: flora of Vietnam, protected areas, achlorophyllous plants, mycoheterotrophy, parasitism Non-photosynthetic, or holo-heterotrophic, plants represent a noteworthy group of organisms. They do not produce chlorophyll (or produce it in extremely small amounts), and therefore they are not capable of photosynthesis and lack green coloration in all parts of the plant.

Orchids of Bhutan III: the Genus Epipogium in Bhutan by Stig Dalström and Dhan Bahadur Gurung
Orchids of Bhutan III: The Genus Epipogium in Bhutan BY STIG DALSTRÖM AND DHAN BAHADUR GURUNG IN THE ORCHIDS OF BHUTAN (Pearce and Cribb 2002), we can read the following: “The genus Epipogium was established (as Epipogum) in 1747 by S. [sic. J.]G. Gmelin in his Flora Siberica [sic. Sibirica]. Since the original description, there have been no less than four different published spellings for the genus, causing a confusion that was reviewed by Sprague and Green (1937). Most authors have since used Epipogium, the earliest use of which was in 1792 by Moriz Balthasar Borkhausen in his Tentamen Dispositionis Plantarum Germaniae.” Pearce and Cribb (2002) also mention that the genus includes TIG DALSTRÖM 1 TIG DALSTRÖM 2 “about” five species S S with Epipogium aphyllum Sw. other scientifically described “names,” [1] Epipogium aphyllum, myco- reported from a including varieties and forms, have few locations in received the same treatment. parasitic plant habit in leaf Stig Dalström Bhutan; Epipogium Plants of Epipogium were for a long mold, Högberget, Sweden. roseum (D.Don) time considered to be “saprophytic” [2] Epipogium aphyllum, with Lindl. from Darjeeling and Sikkim, India; (living on dead material), and existing and Epipogium sessanum S.N.Hegde & in a harmonious symbiotic relationship nonresupinate flowers, Hög- A.N.

Classification of the Orchidaceae and their probable origin. Telopea 2(4): 413-424-Though we need much more data, especially on primitive orchids, increased knowledge is leading to a more natural classification. The Apostasioideae and Cypripedioideae, with 2 or 3 fertile anthers, are each amply distinct. The monandrous orchids with erect anther and soft pollen form 2 distinct groups: the Orchidoideae have the anther generally surpassing the rostellum, lack subsidiary cells, and most groups have root-stem tuberoids; while the Spiranthoideae have the rostellum subequal to the anther, often have mesoperigenous subsidiary cells, and lack root stem tuberoids. The Epidendroideae are the major phyletic group, about 80OJo of the family. They often have perigenous subsidiary cells, and members with soft pollen generally have the anther bending downward during development. The vandoid tribes do not show such clear ontogenetic bending, but current research on seed structure suggests that the vandoid level of evolution has arisen independently 3 or 4 times from different epidendroid groups, with much parallelism.

For reasons explained in the the Orchidales subdivided into three viz. the present paper are families, Apostasiaceae, Cypripediaceae and Orchidaceae. The principal differences between these families are shown in the form of tables. Orchidaceae two and In the subfamilies are recognised amply circumscribed, viz., the Orchidoideae and the Epidendroideae, the latter again being subdivided into the two contribes Neottianthae and Epidendranthae. The androecial morphology is discussed in detail in connection with atavistically with the of developed stamens, presence staminodes (or supernumerary stamens) and with the floral morphology of certain taxa. The auricles are not regarded staminodes because in flowers with as they persist supernumerary (atavistically re-appeared) stamens and also because they lack vascular bundles. The gynostemial Australian and other considered wings in some genera (Diuris, Prasophyllum, ones) are to be of androecial derivation The less conspicuously winged but vascularised of the of likewise androecial margins gynostemium many Epidendroideae represent elements incorporated in the column. The suggestion, made by E.
