Description from Flora of China

Cerochilus Lindley; Goodyera sect. Rhamphidia Lindley; Rhamphidia (Lindley) Lindley.

Herbs, terrestrial. Rhizome ascending, elongate, several noded, fleshy; roots arising from rhizome nodes, elongate, fleshy, pubescent. Stem glabrous, leafy. Leaves subrosulate or scattered along stem, narrowly ovate to elliptic, usually asymmetric, membranous to slightly fleshy, with a petiole-like base dilating into tubular amplexicaul sheath. Inflorescence pubescent, with a few scattered sheathing sterile bracts and several to many flowers in a terminal raceme. Flowers not resupinate; ovary not (or rarely slightly) twisted, glabrous or pubescent. Sepals free, similar, outer surface glabrous or pubescent; lateral sepals embracing base of lip. Petals connivent with dorsal sepal and forming inverted hood, usually narrower than sepals, membranous; lip adnate to margin of column, 2-partite or with a short mesochile and 3-partite; hypochile concave, saccate or cupular, containing 1 to several papillose, warty or lamellate calli on either side of midvein; mesochile (when present) with involute margin; epichile entire and tapering or 2-lobed. Column short, with thin to fleshy winglike appendages at apical margin; anther ovoid, 2-locular; pollinia 4, in 2 pairs, clavate, granular-farinaceous, basally attenuate into short caudicles, attached to solitary ovate viscidium; rostellum erect, relatively long, bifid; stigma lobes separate and placed at apical corners of column. Capsule erect, fusiform.

Records of Hetaeria cristata Blume from Taiwan and Hong Kong are based on misidentifications of Rhomboda tokioi and R. abbreviata, respectively (see p. 68).

About 30 species: tropical Africa and Asia, extending to New Guinea, NE Australia, and the Pacific islands; six species in China.
