Orchidaceae, V. S. Summerhayes. Flora of Tropical East Africa. 1968

Habit
Erect mostly small terrestrial herbs arising from small tubers and in the Flora area usually growing in very shallow soil or leaf-mould in forest
Stem
Stems with 1-several sheathing scale-leaves (cataphylls) at the base
Leaves
Leaves 1-few, alternate or opposite, rarely almost obsolete
Flowers
Flowers small, mostly under 2.5 cm. long, white, yellow, green, pink or magenta, solitary or in several- many-flowered racemes; bracts leaf-like
Calyx
Dorsal (intermediate) sepal united with the petals to form a structure which varies from an almost flat limb to an elongate spur; lateral sepals each with a conspicuous spur or pouch near the inner margin (lacking in one South African species)
Corolla
Petals variously shaped, often falcate, obliquely acute or lobed at the apex, sometimes auriculate at the base
Labellum
Lip remarkably modified, its claw joined to the face of the column and ascending above it, variously curving into the spur if present, often dilated into a smooth or papillate, straight or reflexed limb and usually bearing a simple or 2-lobed appendage which varies greatly in shape from species to species
Column
Column erect, mostly stout; rostellum large, membranous, 2-lobed, produced in front into 2 rigid cartilaginous arms (fitting into the lateral sepal-pouches when in bud) holding the glands of the pollinia at their apices; anther-bearing part of column horizontal or ascending; anther-loculi distinct, parallel, ± approximate; pollinia-granules secund in a double row on the margins of the flattened caudicles which curl up in a spiral on removal; staminodes present in some species; stigma 2-lobed, the lobes situated on either side of the adnate claw of the lip
Fruits
Capsule cylindrical or ovoid, ribbed.

Dorsal sepal adnate to the petals to form an open or elongate hood; lateral sepals sometimes partly joined, each with a sac-like spur near the inner margin (spur lacking in 1 or 2 species).
Corolla
Petals variously shaped, sometimes auriculate at the base.
Labellum
Lip greatly modified, its claw joined to the face of the column and ascending above it, variously curving into the spur if present, often dilated into a smooth or papillate limb and usually bearing a simple or 2-lobed appendage which varies greatly in shape from species to species.
Column
Column erect; rostellum large, 2-lobed, produced in front into 2 rigid cartilaginous arms with the viscidia at their apices.
Anthers
Anther loculi distinct, parallel; pollinia-granules secund, in double row on the edges of the flattened caudicles; staminodes present in some species.
