Description
|
Glabrate, erect, branched herb to 1 m tall with fistulose stems. Leaves entire, three- or five-lobed, often all on the same plant, entire leaves mostly 5-6 cm long and 3-4 cm broad, broadly ovate, rounded at the base, acuminate at the apex, the lobed leaves 9-11 cm long and 6-10 cm broad, the sinuses broadly rounded, approaching the midvein, glabrate with scattered hairs on the lamina, silvery beneath when fresh; petioles 1.5-5 cm long, slender, narrowly winged. In- florescence a short, 1-6-flowered raceme at a dichotomy of the stem, the peduncle 1-2 cm long, glabrous, drying stramineous; pedicels ca. 1 cm long, broadening sharply into the calyx. Flowers inconspicuous, calyx 2 mm long, lobed about halfway, the lobes deltoid, hardly accrescent in fruit, glabrous; corolla white or yellowish, 10-12 mm long, lobed about halfway; filaments affixed to the dorsal surface of a membranaceous ring inserted near the base of the corolla tube, ca. 1 mm long, about half its length consisting of an expansion visible from the dorsal side of the anther, the anthers lanceolate, ca. 6 mm long, acuminate apically with 2 small terminal pores surmounted by conspicuous rims; ovary elongate-conical, the stigma punctiform. Fruit ripening white, ca. 2 cm long, ellipsoid, immature fruits striped or not; seeds yellow, ca. 1.5 mm long, compressed.

Note
|
This species is distinctive in its widely lobed leaves, lack of pubescence, and the short stramineous peduncles bearing large fleshy fruits. Collections seen are all from the Pacific lowlands of eastern and central Panama. The connective enlargement is small and easily overlooked. The nature of the fruit and the position of the inflorescence are those of the genus Cyphomandra. Many of the petioles have somewhat clasping bases.
