Species Description - (MICROCEPHALUM.) Stemless; lower leaf-surfaces minutely scurfy, the flower sparsely pilose. Petioles half the length of the blades, or less, broad but closely involute; costate, with finer intervening nerves. Blades 1.5 to 2 dm. long, obovate, obtusish, involute in drying, very thin, bright-green above, very pale beneath. Heads closely sessile upon the rhizome, crowded, the bracts, subtended by membranaceous keeled bractlets. Ovary oblong, a little wider at the truncate summit, densely setaceouspilose at the base. Sepals about 1 cm. long, one a little wider, oblong with rounded summit, hyaline, finely very many-nerved. Corolla-tube nearly 3 cm. long, very slender, the rest of the flower 1 cm. long, the corolla-lobes subequal, hyaline, 13- or 15-nerved, broadly oval. Petaloid filaments about two-thirds the length of the petals, a short recurved vermiform appendage on one side. Lip a little longer than the latter, subrotund, entire, very thin. Exserted portion of style broadly margined, complanate, the summit involute, the terminal portion small. Capsule 1 cm. long, the three seeds 6 mm. long, light-brown, lightly and coarsely tuberculate.
