Ascocentrum, abbreviated as Asctm in horticultural trade, is a small genus belonging to the orchid family (Orchidaceae). The type species is Ascocentrum miniatum (Lindl.) Schltr. ex J. J. Sm. (originally as Saccolabium miniatum Lindl.).
They occur mainly in warmer to intermediate, humid climates of the foothills of the Himalayas, in Myanmar, Thailand, Malaysia, the Philippines, Java and Borneo.
These monopodial epiphytic orchids grow on deciduous trees. They have a short, simple to bifurcate stem (max. 15-18 cm) with an upright, compact, conical to racemose inflorescence, consisting of smaller brightly colored flowers. These flowers have a prominent spur and a strap-like lip. Their bright colors vary between yellow, orange, red, orchid or cerise.
The chromosome number is 2n = 38.
They are popular among orchid lovers because they resemble the compact Vanda-like species. Nevertheless their cultivation is rather difficult.

They are generally crossed with Vanda species into numerous intergeneric hybrids, giving the following nothogeneric names (i.e. the name at generic rank for a hybrid between representatives of two or more genera)
