Dendrochilum (commonly abbreviated Ddc. in horticulturehttp://www.rhs.org.uk/RHSWebsite/files/87/87be8b1e-908e-4e04-9ee6-30c438354458.pdf{{dead link|date=December 2016 |bot=InternetArchiveBot |fix-attempted=yes }}) was a genus of epiphytic, lithophytic and a few terrestrial flowering plants in the orchid family (Orchidaceae). It is now considered to be a synonym of Coelogyne Lindl.{{cite POWO |id=30175266-2 |title=Coelogyne Lindl. |accessdate=17 November 2023}}
The name of this genus was derived from Ancient Greek words {{transliteration|grc|dendron}} ("tree"), and either {{transliteration|grc|cheilos}} ("lip")Schubert, R., & Wagner, G. (1988). Botanisches Wörterbuch (9th edition). Stuttgart: Gustav Fischer. or {{transliteration|grc|chilos}} ("green food"),{{Citation needed|reason=According to which source? Schubert and Wagner's Botanisches Wörterbuch only mentions dendron and cheilos.|date=August 2019}} alluding to either the flowers' large lip or to their epiphytic growth. These orchids are popular among orchid collectors.{{cite web |title=Dendrochilum, The Dainty Orchids from the Philippines |url=https://orchidrepublic.com/blogs/about-orchids/dendrochilum-orchids?srsltid=AfmBOoo5J1VuK0vvVh1BDpeJudsJkbEnthuzhLzsCf2x_sXv30NuKHIM |website=Orchid Republic |date=5 November 2018 |access-date=23 December 2024}}
Distribution and description
Image:Dendrochilum glumaceum 26.jpg (D. glumaceum) seen up close]]
Dendrochilum are distributed at higher elevations in the humid rainforests throughout the Malesian region, with some in the surrounding lands; thus they occur from Southeast Asia to New Guinea. However, most species are found on Borneo or the Philippines.[http://apps.kew.org/wcsp/namedetail.do?name_id=59547 Kew World Checklist of Selected Plant Families]
This genus produces miniature, fragrant, star-shaped flowers that are generally produced in two rows on erect or arching pendant, many-flowered racemes. These inflorescences can grow to a length of {{convert|50|cm|abbr=on}} (e.g. in the Hay-scented Orchid, D. glumaceum). The stems are ovoid to cylindrical, striped, sharply reduced pseudobulbs, about {{convert|4|-|10|cm|abbr=on}} long, with green to brown bracts at their base. Each carries one or two tough, erect and lanceolate leaves, usually about {{convert|20|cm|abbr=on}} long, with narrow petioles. The elliptical leaves of the Long-leaved Dendrochilum (D. longifolium) may grow to a length of {{convert|40|cm|abbr=on}}.
Taxonomy
The precise number of species is disputed; many websites accept as few as 100 or so, while others recognize far more. For example, the World Checklist of Monocotyledons{{Citation needed|date=December 2008}} lists 390 records, including names that have become synonyms. Numerous new taxa have become known in recent decades.e.g. Pedersen (1997), Wood (1997)
Many of these orchids (67 species in the list used here) were named by Johannes Jacobus Smith, an eminent Dutch botanist. The genus' type species, described by Carl Ludwig Blume in 1825, is Dendrochilum aurantiacum of Java and Sumatra. Several species were formerly separated in Acoridium (established by Christian Gottfried Daniel Nees von Esenbeck and Franz Julius Ferdinand Meyen in 1843) or Platyclinis (established by George Bentham in 1881), but these two taxa are now regarded as synonyms of Dendrochilum.
