shrubby, slender, minutely viscid, nearly glabrous; branches virgate, straight; leaves sub-distant, on short petioles, cuneate-obovate, truncate, toothed above, glabrous, viscidulous; stipules minute, subulate; peduncles racemose, one-flowered, jointed and minutely bracteolated below the flower; calyx sparsely hairy and ciliate, deeply 5-parted, segments broadly subulate, mid-ribbed; petals thrice as long as the calyx, broadly obovate, expanded; fil. broadly spathulate, much longer than the oblong, blunt anthers; capsule with ten, plumoso-villous horns. Readily known by its large, expanded flowers, which are very like those of Mahernia grandiflora, or of an Oxalis. The stamens and inflorescence are those of a Hermannia. It seems to be a small, slender and slightly branched shrub, more or less viscid, and nearly glabrous, save for a few scattered, stellate hairs.
