Description
Species Description - Lower leaf-surfaces and inflorescence lightly puberulent. Stems elongate, slender, reclining or drooping, strongly sulcate in the dried state. Petioles 1 cm. long, thinly margined, the blades 4 to 7 cm. long, 2 to 3 cm. wide, lance-oblong, the base very abruptly contracted into the petiole, acuminate and acute, the principal nerves 7 to 9, with as many finer intermediate ones. Umbel terminal, compound, 4-branched, in my specimens, the branches 2- to 3-flowered, the bracts lanceolate, 2 cm. long, abruptly contracted into an attenuate point. Branches of the umbel slender, 3 to 5 cm. long, the bractlets similar to the bracts, but much smaller, the pedicels slender, shorter than the flowers, which are nearly 3 cm. long, and 2 cm. broad as pressed, campanulate and lightly curved. Sepals obovate, rose-colored externally and cream-colored within. Petals of about equal length, cream-colored with fine purplish spots, spatulate, the lower third being narrowed into a claw. Filaments puberulent. Ovary very small. Style stout, nearly equaling the perigone, the three recurved stigmas about 2 mm. long. "A vine, 10 meters long, in cultivated ground.'' The petioles are more or less twisted, as though affording support to the stem.

Discussion
Species near B. edulia, but peculiar in its well-developed petioles.
