Synonyms: ''Bulbophyllum minutissimum'' F. Muell. 1878; ''Dendrobium minutissimum'' F.Muell. 1866; ''Dendrobium nummulifolium'' R.King 1879; ''Oncophyllum minutissimum'' (F.Muell.)

Kuntze 1891; ''Bulbophyllum moniliforme'' Par & Rchb.f 1874.〔(The Internet Orchid Species Photo Encyclopedia )〕 ''O. minutissimum'' grows in coastal districts on trees and rocks, along streambanks and in mangroves and in rainforest to dry sclerophyll forest; altitude: sea level to 500 metres. It is said to also occur in Laos, Cambodia, Vietnam, India, Myanamar (Burma) and Thailand.〔 Description: Epiphyte or epilith (a plant that grows on stone or stone-like material) with rhizomes prostrate, 2–4 mm between pseudobulbs. The plant forms a dense mat; pseudobulbs flattened-globose, 2–3 mm diam., smooth. The pseudobulbs are very small and turn red in strong light.〔()〕 or Red Bead Orchid〔''A complete Guide to Native Orchids of Australia, including the island territories'', pp. 427-428. David L. Jones. 2006. New Holland Publishers, Frenchs Forest, N.S.W. 2086 Australia. ISBN 1-877069-12-4.〕 Leaves are narrow-triangular about 1 mm long, 0.2–0.3 mm wide, papery, curved and concave. Oval, hairy flowers c. 0.3 cm long, 1-flowered. Whitish to reddish with wide dark red stripes. Labellum red. Ovary hairy. Flowers: October–November It is said to possess small hollow pseudobulbs that contain stomata (organs for gas exchange) on their inner surface. This minimizes the surface area and the danger of loss of water by transpiration. A very similar species is the closely related ''Oncophyllum globuliforme'' or Green Bead Orchid, the only other member of the genus Oncophyllum. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oncophyllum minutissimum」の詳細全文を読む スポンサード リンク
