Cranichideae (Lindl.) Endl., Man. Bot. Suppl., 2, 18 (1842). Type genus: Cranichis Sw.

Terrestrials or lithophytes, herbaceous rarely epiphytes. Roots fleshy, in tufts or apart. Rhizome thick fleshy, or in subtribe Pterostylidinae with tubers. Leaves convolute, not plicate, fleshy, spirally arranged along the stem or a rosette in subtribe Pterostylidinae Inflorescence terminal, erect, 1- to many-flowered, often pubescent or glandular; floral bracts persistent. Flowers resupinate, rarely not, usually small, often more or less tubular and not opening widely. Ovary twisted or not. Sepals usually rather simila. Lateral sepals often somewhat oblique at the base, in some Pterostylidinae at the base fused. Petals usually thinner than the petals, often adnate to the Median sepal forming a hood. Lip mobile or not, entire, 2- or 3-lobed; at the base entire, saccate or spurred; spur free or more or less adnate to the ovary, often inside at the base with papillae or other appendcages. Columm short and massive to elongate; column foot present or absent; stigma entire or 2-partite, ovate or elliptic, concave or flat; rostellum elongate, in many species beak-like, with acute or truncate apex; viscidium with 1 to several cell layers; tegula (if present) a lamella; some genera with a fleshy hamulus; anther with a short filament, erect, cordate to oblong-cordate, 2-locular; pollinia 2 or 4, narrowed toward the base, powdery and sectile or firm; staminodes wing-like, thin or relatively thick, fused with the filament and margins of the stigma, forming a distinct dorsal clinandrium.

Tribe Cranichideae in New Guinea contains 3 subtribes:



1a. Pollinia sectile; stipes distinct. Spur, present or absent == Goodyerinae
1b. Pollinia granular; stipes absent but sometimes with a hamulus. Spur-like structure formed by the mentum and the base of labellum sometimes present == 2

2a. Lip mobile. Median sepal and petals forming a distinct hood == Pterostylidinae
2a. Lip not mobile. Median sepal and petals adnate or not, rarely forming a hood == Spiranthinae
