Agrostophyllum is a genus with about ninety species from the orchid family (Orchidaceae). The genus name is derived from the Greek words agrostis ("grass") and phyllos ("leaf"), referring to the grass-like appearance of the leaves of some species.[2]
These epiphytic orchids occur in tropical lowland forests, growing on trunks or branches of trees. They are found from the Seychelles, Madagascar , India , Sri Lanka, Malaysia, Indonesia to the Pacific Islands. The center of diversity is to be found in New Guinea, with at least 45 species.[1][3]
These orchids have elongate, frequently pendulous stems with dense leaves that overlap at their base. They show peculiar, ball-like inflorescences of many bracts, bearing small flowers.
Sections
There are four sections in this genus :[4]
- Dolichodesme - elongated inflorescence which may have the form of a spike, but also may be partly branched as in a panicle.
- Agrostophyllum – Leaves somewhat longer; small flowers on a shortened apical head; a few species may only develop one or two flowers.
- Oliganthe - characterised by a much elongated rhizome and pendant sympodia. Leaves and flowers similar to those of the previous section.
- Appendiculopsis - slightly elongated, short creeping rhizomes; distichous, crowded, oblong leaves, at right angles with axis of stem, abruptly truncated at base, with a small petiole; terminal or lateral inflorescence; used to belong to the genus Appendicula.
