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.

The mature stomata were laterocytic, staurocytic, anisocytic, paracytic and diacytic. The abnormalities noticed include unopen stomatal pore, two stomata sharing one subsidiary cell, one guard cell, parallel contiguous and aborted guard cell. A. godseffiana can be distinguished by parallel contiguous on both surfaces. Curved uniseriate non-glandular trichomes were restricted to A. wilkesiana. Two stomata sharing one subsidiary cell occurred only on the lower surface of A. hispida. The shapes of epidermal anticlinal cell walls, guard cell areas, stomata index and trichomes varied. The differences are of taxonomic importance and can be used to identify and delimit each species by supporting other systematic lines of evidence.

Historical Setting of the Guianan Plant Heritage The Guianas are embedded high in the green shoulder of northern South America, an area once known as the "Wild Coast". They are the only non-Latin American countries in South America, and are situated just north of the Equator in a configuration with the Amazon River of Brazil to the south and the Orinoco River of Venezuela to the west. The three Guianas comprise, from west to east, the countries of Guyana (area: 83,000 square miles; capital: Georgetown), Surinam (area: 63, 037 square miles; capital: Paramaribo) and French Guiana (area: 34, 740 square miles; capital: Cayenne). Perhaps the earliest physical contact between Europeans and the present-day Guianas occurred in 1500 when the Spanish navigator Vincente Yanez Pinzon, after discovering the Amazon River, sailed northwest and entered the Oyapock River, which is now the eastern boundary of French Guiana.

ABSTRACT The Lower Gangetic Plains particularly from Dakhineshwar to Uluberia, West Bengal was investigated for the taxonomic and ecological analyses of its naturalized vegetation. The physicochemical studies of soil were also performed from this site. It was observed mangrove plants prevailed at zones where higher percentage of silt was present, while inland plants were grown where percentage of sand and clay were higher. A total of 95 plant species were recorded and their phytoclimatic study was done and the result revealed that percentage of phanerophytes was maximum among others. From phytosociological study it was observed that mangrove associates such as Cryptocoryne ciliata and Oryza coarctata showed highest IVI values, on the other hand Cynodon dactylon was dominated at non-mangrove site. The present analyses indicated existence of two distinct plant communities in the site with more or less stable vegetation pattern. Keywords: Lower Gangetic Plain, vegetation, diversity, community *Corresponding author May–June 2017 RJPBCS 8(3) Page No. 1558 ISSN: 0975-8585 INTRODUCTION Though India has a wide range of vegetation comprising of tropical rain forest, tropical deciduous forest, thorny forest, montane vegetation and mangrove forest, the Gangetic Plains in India form an important biogeographic zone in terms of vegetation characterized by fine alluvium and clay rich swamps, fertile soil and high water retention capacity.

Mitchell Arid Zone Research Institute, Animal Industry and Agriculture Branch, Department of the Northern Territory, Alice Springs, N.T. 5750. Abstract This paper presents a synopsis of the nomenclature of the family Lythraceae in the Northern Territory. Keysto the genera and species have been prepared. The family Lythraceae has been neglected in Australian systematics, andas a result both the taxonomy and nomenclature are confused. Not since the early work of Koehne (1881, 1903) has there been any major revision of the family. Recent work has been restricted to regional floras (Polatschek and Rechinger 1968; Chamberlain 1972; Dar 1975), with Bentham's Flora (1886) being the most recenton the family in Australia. From a survey of the available literature the author has attempted to extract all the relevant names applicable to Australian material and to present them solelyas a survey of the nomenclature of the group. No type material has beenseen, and the only material examined was that lodged in the Department of the Northern Territory Herbariaat Alice Springs (NT) and Darwin (DNA).

  • Research Priorities and Future Directions in Conservation of Wild Orchids in Sri Lanka: a Review
    Nature Conservation Research. Заповедная наука 2020. 5(Suppl.1): 34–45 https://dx.doi.org/10.24189/ncr.2020.029 RESEARCH PRIORITIES AND FUTURE DIRECTIONS IN CONSERVATION OF WILD ORCHIDS IN SRI LANKA: A REVIEW J. Dananjaya Kottawa-Arachchi1,*, R. Samantha Gunasekara2 1Tea Research Institute of Sri Lanka, Sri Lanka 2Lanka Nature Conservationists, Sri Lanka *e-mail: [email protected], [email protected] Received: 24.03.2020. Revised: 22.05.2020. Accepted: 29.05.2020. Together with Western Ghats, Sri Lanka is a biodiversity hotspot amongst the 35 regions known worldwide. Considering the Sri Lankan orchids, 70.6% of the orchid species, including 84% of the endemics, are categorised as threatened. The distribution of the family Orchidaceae is mostly correlated with the distribution pattern of the main bioclimatic zones which is governed by the amount and intensity of rainfall and altitude. Habitat deterioration and degradation, clearing of vegetation, intentional forest fires and spread of invasive alien species are significant threats to native species. Illegally collection and exporting of indigenous species has been another alarming issue in the past decades. Protection of native species, increased public awareness, enforcement of legislation and introduction of new propagation techniques would certainly bring a beneficial effect to the native orchid flora. Conduct awareness programs, strengthen existing laws, and reviewing the legal framework related to the native orchid flora could be vital for future conservation. Apart from the identification of new species and their distribution, future research on understanding soil chemical and physical parameters of terrestrial habitats, plant association of terrestrial orchids, phenology patterns and interactions of pollinators, associations with mycorrhiza, effect of invasive alien species and impact of climate change are highlighted.
