Botanical Description

P. begoniifolium is a small herbaceous plant of the Campanulaceae family. [1]

The stem is procumbent, measures 30-60 cm long, thick, villous chiefly at the summit, with fasciculated hairs. [1]

The leaves are arranged alternate, simple, conspicuously asymmetrical, obliquely ovate to obliquely lance-shaped or obliquely reniform, 10-30 cm x 6-13.5 cm, base is rounded to cordate on one side, strongly excised-concave on other side, apex is shortly acuminate, finely but sharply serrate and fleshy. The petiole is 2-4 cm long while stipules are absent. [3]

The inflorescence is terminal or axillary, usually solitary, 4-5 cm long, at first dense and scorpioid, ultimately lax and almost straight. Flowers are bisexual, 5-merous and subtended by orbicular-obovate 5-9 mm long bracts. The sepal tube is 4-5 mm x 3 mm, sparsely pilose, unequal lobes which are ovate to orbicular, 2-2.5 mm long. Petal is 3 mm long with short tube, spatulate-obovate lobes and slightly fleshy. The stamens are alternate with petal lobes. [3]

The ovary surrounded by the calyx, and connected with it by 5 longitudinal septa or processess, from which the stamens spring, 3-4 celled, many-seeded; placentae from the inner angles of the cells. The style is short and thick. [1]

The stigma large, thick, 3-lobed. The capsule 3-4 celled, containing numerous seeds, arranged in convex placentae. [1]

The fruit is an ellipsoid, 8-9 mm x 3-4 mm indehiscent berry and many-seeded.
