ORCHIDS

Corycium Sw., Kongl. Vetensk. Acad. Nya Handl. 21: 220 (1800).
Description:
Terrestrial herb with undivided sometimes stalked tubers. Stem erect, leafy; leaves radical and cauline, linear or oblong, suberect or sometimes spreading, flat or sometimes crisped. Inflorescence terminal, many-flowered, often densely spicate; bracts lanceolate, shorter or longer than the flowers.
Flowers small to medium-sized, subglobose.Dorsal sepal erect, narrow, concave. Lateral sepals usually united, narrowed at the base and connate into a concave limb. Petals obliquely falcate, curved and united with the margins of the dorsal sepal to form a hood, usually somewhat contracted in front, concave or obliquely saccate at the base.Lip ascending along the face of the column and adnate to it between the stigmatic lobes and rostellum arms, narrowed into a claw below, dilated into a reflexed transversely lunate or 2-lobed limb above, limb more rarely oblong or lanceolate; produced above the junction with the column into a large reflexed or erect variously-shaped fleshy appendage. Column short, dilated, produced in front into 2 horizontal arms, holding at their extreme ends the glands of the pollinia; anther cells more or less distant, placed in front of or sometimes behind the arms of the rostellum, erect or ascending, glands of the pollinia uppermost; stigma posticous, pulvinate, lunate or 2-lobed, or with 2 lateral and distant stigmas.
