Pleioceras Baill.

Shrubs, lianas or trees up to 9 m. high, with white latex. Branches unarmed, with pale lenticels; branchlets terete, often sulcate when dry. Leaves opposite, those of a pair equal or subequal, shortly petiolate; lamina acuminate, rounded or cuneate at the base. Inflorescences terminal, paniculate, several- to many-flowered, lax. Lower bracts leafy; others narrowly oblong, acute. Flowers actinomorphic except for the sometimes slightly unequal sepals, small; calyx persistent beneath the fruit; sepals green, connate at the base, ovate, imbricate, entire, pubescent or glabrous outside, ciliate; corolla subhypocrateriform; tube yellow and violet or dark-red, ventricose in the middle, outside glabrous at the base and minutely pubescent at the apex, inside at the apex just below the appendages with a narrow pilose zone; lobes yellow with a brownish-violet tinge, in the bud overlapping to the left; appendages bright yellow, in a set of 1–3, shortly truncate or filiform, glabrous or pubescent, plus 2–4 long filiform. Ovary superior, subglobose; carpels two, free, rounded; disk none; style split at the base; clavuncula with a thin ring at the base, almost cylindric, covered by the anthers and inside with the triangular swellings of the connectives adnate to the clavuncula. Ovules numerous, in several rows. Follicles 2, spreading, almost free, pendulous, slender, adaxially dehiscent, glabrous; wall thinly coriaceous, striate. Seeds numerous, in two or more rows, linear to very narrowly oblong, glabrous, with a ± dense tuft of retrorse hairs at the apices, embryo large, surrounded by the very scanty whitish endosperm.
