'''''Agrostylum''''' is a [[genus]] with about ninety [[species]] from the orchid [[family (biology)|family]] ([[Orchidaceae]]). The genus name is derive form the Greek words ''agrostis'' ("grass") and ''phyllos'' ("leaf"), referring to the grass-like appearance of the leaves of some species.

These [[epiphyte|epiphytic]] orchids occur in [[Tropics|tropical]] lowland forests, growing on trunks or branches of tress. 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.

These orchids have elongate, frequently pendulous [[Plant stem|stems]] with dense [[Leaf|leaves]].that overlap at their base. They show peculiar, ball-like [[inflorescence]]s of many bracts, bearing small flowers.

==Species==
There are four sections in this genus :
*Dolichodesme - elongated inflorescence which may have the form of a spike, but also may be partly branched as in a panicle.
*Eu-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.
