SECTION Uncifera Schlechter 1913


Characterized by the very short rhizome and caespitose habit, ramicauls that are distinctly shorter than the thinly coriaceous leaves and the laterally arising, successively to simutaneously opening, few to many flowered, racemose inflorescence subtended by an annulus a short distance below the abscission layer. The small flowers have a three-veined dorsal sepal and is essentially free from the laterals which are connate at least above the middle. The petals are membraneous, simple and single veined. The lip is lobed at the base and the lobes are modifications of the uncinate form. The disc is smooth to variously sulcate between a pair of carina that extend forward at the base. There is also a converging pair of calli extend forward from the bases of the lateral lobes. The lip base is simply hinged to the short column foot. The semi-terete column is variously toothed at the apex and covers the anther. The anther has a deciduous anther cap and has a pair of free, obovoid pollina. The ventral stigma lies behind the rostellum
