Description
Species Description - Leaves, etc., scabrous, the internodes nearly glabrous. Stems occasionally nearly a meter high, slender, simple or little branched, the branches erect. Internodes mostly longer than their leaves, quadrangular, the angles slightly winged. Stipular setae filiform, rigid, unequal, those nearest the leaves reaching 8 mm. in length. Leaves sessile, to 3 cm. long, linear-lanceolate, acuminate at both ends, obtusish, entire, margin strongly revolute, thick and rigid, the midrib very stout and prominent beneath. Cymes verticillate, very dense and many-flowered. Calyx-tube narrowly turbinate, the limb 4-parted, with several small intermediate teeth, lobes somewhat unequal, to 2 mm. long and a little longer than the tube, in fruit, lance-linear or subulate, rigid, whitish with a broad green midrib, obtusish. Corolla 3 mm. long, 4-parted nearly to the base, the lobes oblong, obtuse, white, bearing a brown gland in the center, above the middle. Anthers nearly sessile, in the sinuses, oblong, nearly 1 mm. long, oblong. One of the mericarps tardily dehiscent on the inner face.

Discussion
It would appear that a plant with a petaloid appendage of this kind should be generically distinct from Borreria, but all its other characters are in such close agreement with this genus that I scarcely feel disposed to separate it.
