Epidendrum ramosum, the mountain star orchid,[1] is a neotropical species of reed-stemmed Epidendrum orchid which grows both epiphytically and terrestrially at altitudes near 1 km.
Description
[edit]Epidendrum ramosum stems do not swell into pseudobulbs, are highly branched, and are covered with close, tubular sheathes, the upper ones bearing longish leaves which are rounded at the apex.[2] The short, scaly, apical peduncle bears a raceme with large, alternate floral bracts which nearly cover the long pedicellate ovaries of the few green-yellow flowers.[3] The sepals are oblong-acute, 5–6 mm long and 2 mm wide; the petals are narrower. The cordate acute lip is adnate to the column to its apex, has no lateral lobes, and bears a callus consisting of two keel-like ridges near the column apex. The four pollinia are white.
Homonymy
[edit]Five varieties of E. ramosum have been published,[4] three of which are now recognized as separate species:
- E. ramosum var. imbricatum Ames, F.T.Hubb. & C.Schweinf is a synonym for E. paranaense Barb.Rodr.
