“…Every year botanists discover over one hundred new orchid species (e.g. Carnevali et al 2014;Kolanowska 2015;Noguera-Savelli et al 2008;Vale et al 2014). Clearly, our knowledge of orchid genetic diversity is fairly incomplete, and there is the prospect that many orchid species may be lost before their discovery.…”

“…Only 4% of the original cover of tropical dry forest remains in Colombia, and most deforestation are occurring in the Amazon and Andean regions (Cavelier and Etter 1995;Fandiño and Wyngaarden 2005;Pizano and García 2014). In the Chocó biogeographic region along the Pacific littoral, which still retains a high proportion of natural forest habitat, the annual average of deforested area moved from 2,874 ha per year in 2012-2013 to 24,025 ha per year in 2015(IDEAM 2015. In addition to habitat degradation, orchids, being of commercial interest, are subject to the pressure of collection from wild populations (Calderón-Sáenz 2007).…”

“…It could be noted that Brazil has the highest number of published works both on propagation and germplasm conservation, while for some countries only researches referring to propagation of native orchid species are reported and for other countries (Guyana, Paraguay, Trinidad and Tobago, Suriname, Uruguay) there were no registered works in any of the topics.

Orchids are an important part of plant biodiversity on the planet due to their high variability among species and their habitats. South America presents more than thirty percent of all known orchid species, being Colombia, Ecuador, Brazil, Peru, and Bolivia between the richest countries in the world in terms of orchid biodiversity. Nevertheless, concerning to the orchid conservation status, in Colombia precisely orchids occupy the unlucky first place as the plant family with the highest number of threatened species. Similar situation is happening in the rest of the South American countries. The two main threats to orchid survival are both anthropogenic: the first one is deforestation, and the second largest threat to orchids is collection from the wild. One desirable action to safeguard these endangered species is to develop procedures that make possible their massive propagation, which should provide material for the eco-rehabilitation of specimens into their natural habitats, the exchange with other entities, the supply to orchid merchants for avoid extractions of nature, and the availability of material for future research. Likewise, the development of systems that allow the ex situ conservation of orchid germplasm is imperative. This chapter reviews the progresses of different in vitro approaches for orchid propagation and germplasm conservation, safeguarding the genetic biodiversity of these species. Several study cases are presented and described to exemplify the protocols developed in the Botanical Institute of Northeast (UNNE-CONICET) for propagating and long-term storing the germplasm of wild orchids from Argentina (Cattleya lundii, Cohniella cepula, Cohniella jonesiana, Gomesa bifolia, Aa achalensis, Cyrtopodium brandonianum, Cyrtopodium hatschbachii, Habenaria bractescens). Moreover, it has been attempted to put together most of the available literature on in vitro propagation and germplasm conservation for South American orchids using different explants and procedures. There are researches of good scientific quality that even cover critical insights into the physiology and factors affecting growth and development as well as storage of several orchid materials. Anyway, studies are still necessary to cover a mayor number of South American species as well as the use of selected material (clonal) for both propagation and conservation approaches.

Habenaria is almost cosmopolitan in distribution having predominantly terrestrial orchids, however; a remarkable epiphytic species with some unique morphological characters was collected from Nepal. We conducted a molecular phylogeny of this unusual Habenaria species using nuclear (ITS) and chloroplast (matK, rbcl) DNA sequence regions to infer its systematic position. Our molecular analyses and morphological treatment recognized this newly collected plant as an undescribed species. This species is described here which is closely related to Habenaria plurifoliata but can be distinguished by having its multiple growing callus-shaped tuber, smaller stature with short stem, longer and wider oblanceolate leaves, peduncle with a foliaceous bract and only one sterile bract, lateral sepals oblong, obtuse, petal apex obtuse, lateral lobes of lip spreading upwards, spur not exceeding the ovary and pedicel.
