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. Stems with 1-several sheathing scale-leaves (cataphylls) at the base. Leaves 1-few, alternate or opposite, rarely almost obsolete. Flowers small, mostly under 2*5 cm. long, white, yellow, green, pink or magenta, solitary or in severalmany-flowered racemes; bracts leaf-like. 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). Petals variously shaped, often falcate, obliquely acute or lobed at the apex, sometimes auriculate at the base. Lip remarkably modified, its claw joined to the

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 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-loduli distinct, parallel,

It has been suggested that the basal appendages on the lip in species 1-5 (and possibly even 6) are not homologous with the true apical appendages found in other species. Summerhayes (Hook., Ic. PI. 33, t. 3270 (1935)) suggests they are due to a splitting of the actual lip-claw. In this group the true appendage may well be represented by the papillate crest on the limb which is visible in some of them. In this account the word appendage has its simple dictionary meaning. The species are readily identified by careful examination of the lip but since the shapes are not easy to describe the key has been supplemented by a plate (fig. 39, p. 220) showing the lips, the species being numbered as in the account that follows.</paragraph>
