Leaf Micromorphology of Some Habenaria Willd
J. Orchid Soc. India, 32: 103-112, 2018 ISSN 0971-5371 LEAF MICROMORPHOLOGY OF SOME HABENARIA WILLD. SENSU LATO (ORCHIDACEAE) SPECIES FROM WESTERN HIMALAYA Jagdeep Verma, Kranti Thakur1, Kusum2, Jaspreet K Sembi3, and Promila Pathak3 Department of Botany, Government College, Rajgarh- 173 101, Himachal Pradesh, India 1Department of Botany, Shoolini Institute of Life Sciences and Business Management, Solan- 173 212, Himachal Pradesh, India 2Department of Botany, St. Bede’s College, Navbahar, Shimla- 171 002, Himachal Pradesh, India 3Department of Botany, Panjab University, Chandigarh- 160 014, Chandigarh, U.T., India Abstract Leaf epidermal characteristics were investigated in twelve Western Himalayan species of Habenaria Willd. sensu lato with a view to assess their taxonomic and ecological importance. The leaves in all species investigated were soft, shiny and devoid of trichomes. The epidermal cells were polygonal in shape but quadrilateral on adaxial surface of H. edgeworthii J. D. Hook. Cell walls were straight except on abaxial epidermis of H. commelinifolia (Roxb.) Wall. ex Lindl. and H. ensifolia Lindl., where they were slightly undulated. The leaves were invariably hypostomatic and possessed anomocytic type of stomata. Additional presence of diacytic (H. plantaginea Lindl.) and twin (H. marginata Coleb.) stomata was of taxonomic implication. Stomatal frequency (per mm2) was lowest (16.01±1.09) in H. edgeworthii and highest (56.84±3.50) in H. marginata, and stomatal index (%) ranged between 11.93±1.14 (H. stenopetala Lindl.) and 27.24±1.26 (H. aitchisonii Reichb. f.). Leaf epidermal features reflected no apparent relationship with species habitat. There were significant differences observed in many epidermal characteristics, which can ably supplement the data available on gross morphology to help in delimiting different Habenaria species. -
Minireview Article the Current Research Status of Endangered
Minireview Article The Current Research Status of Endangered Rhynchostylis retusa (L.) Blume: A Review ABSTRACT Orchids bear the crown of highly evolved ornamental floral specialization in the plant kingdom, but have poor medicinal background. Further, Rhynchostylis retusa (L.) Blume is much less studied plant species among Orchidaceae due to its overexploitation in the wild. This epiphytic herb belongs to the tropical areas and kept under endangered category by CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) that points out its abated natural population. In this sense, the aim is to document the past and present researches upon R. retusa highlighting the traditional and remedial uses, and to ignite the conservation awareness among the people. Keywords: Conservation, medicines, mythology, patents, taxonomy, tissue culture. 1. INTRODUCTION Orchidaceae (monocotyledons) are one of the largest families of the plant world extending from tropics to alpines along with a boon of astonishing beauty in their flowers [1]. Orchids are the richest among angiosperms with diverse species number (approximately >25,000) having epiphytes (more abundant, 73 %), lithophytes and ground plants [2,3]. Fossil records of orchids date back to 100 million years ago [4]. Actually the term ‘orchid’ coming from ‘orchis’ (Greek word) meaning testicle was given by Theophrastus (372-286 B.C.), who reported the use of orchid roots as aphrodiasic. Despite of huge family size, orchids are largely exploited and traded for their ornamental flower diversity but less attention is paid towards their remedial properties. According to Reinikka, the first evidence of the use of orchids as medicines comes from Shênnung’s Materia Medica in 28th century B.C. -

Orchid species of the genus Aa have been described as mostly restricted to high elevations zones in the Andes and mountains of Costa Rica. Here, we record populations of Aa weddelliana at lower elevations in lomas formations from the desert coast of Peru; this is the fourth species of Orchidaceae registered in Peruvian lomas. Furthermore, we illustrate and discuss some floral features ofAa weddelliana. RESUMEN.

J. Orchid Soc. India, 30: 1-10, 2016 ISSN 0971-5371 DEVELOPMENT OF MALLLEEE AND FEMALLLE GAMETOPHYTES IN HABENARIA OVVVALIFOLIA WIGHT (ORCHIDAAACCCEEEAAAE) M R GURUDEVAAA Department of Botany, Visveswarapura College of Science, K.R. Road, Bengaluru - 560 004, Karnataka, India Abstract The anther in Habenaria ovalifolia Wight was dithecous and tetrasporangiate. Its wall development confirmed to the monocotyledonous type. Each archesporial cell developed into a block of sporogenous cells and finally organized into pollen massulae. The anther wall was 4-5 layered. The endothecial cells developed ring-like tangential thickening on their inner walls. Tapetal cells were uninucleate and showed dual origin. The microspore tetrads were linear, tetrahedral, decussate and isobilateral. The pollens were shed at 2-celled stage. The ovules were anatropous, bitegmic and tenuinucellate. The inner integument alone formed the micropyle. The development of embryo sac was monosporic and G-1a type. The mature embryo sac contained an egg apparatus, secondary nucleus and three antipodal cells. Double fertilization occurred normally. Introduction species.

Gulf Coast Orchid Society Newsletter
Gulf Coast Orchid Society Newsletter June 9, 2013 Our June meeting will be held Sunday, June 9, at 2:00 at the Jeff Davis Community College located at the corner of Runnymeade Rd and Debuys; just north of Pass Rd. We will meet in the main cafeteria and then move to the smaller meeting room for the program. The room that we normally use will be closed due to another meeting. PLEASE DO NOT GO INTO THE REGULAR MEETING ROOM. The Orchid’s 101 meeting led by Glen Ladnier will precede the meeting at 1:30 in the smaller meeting room. This month’s topic will be “It’s all in the roots!” PROGRAM: Glen will also do our main program on Native Orchids of South Mississippi. This will be part power point presentation and part live orchids that Glen will bring in. Glen has been working with native orchids for several years. He is currently working with Crosby Arboretum in their efforts to create a native orchid garden. We will also have several plants to sell at the meeting; some of the great plants Walter Taylor donated for the May auction, some plants donated by Jo Ann Vaz and many blooming Phals and Dendrobium purchased earlier in the year. All plants will be prepriced; you can purchase these plants from the time they get to the meeting (around 1:00 PM) until 1:20 and during the break of the regular meeting. Sales will stop just before the Orchids 101 class starts. They will be covered so no shopping or setting plants aside. -
