Flora of Barro Colorado Island

Peperomia rotundifolia

(L.) H.B.K., Nov. Gen. & Sp. 1:65. 1816


Small, creeping, epiphytic herb; stems scarcely 1 mm wide, glabrous or pubescent. Petioles to 5 mm long, basal, usually perpendicular to blade; blades orbicular, to 12 mm diam, fleshy, bicolorous, often sparsely crisp-­pubescent above. Spikes to 2 cm long, little more than 1 mm wide, often on short lateral branches; peduncles short; bracts round-peltate, glabrous. Fruits globose-­ovoid, less than 1 mm long; stigma subapical. Croat 9446.

Common in the forest, usually creeping or pendent from slender branches and within 6 m of the ground. Flowering chiefly in the dry season and the early rainy season, though it has been seen in flower in the middle of the rainy season; perhaps less seasonal than most Peperomia.

The species is apparently closely related to P. ebingeri. See that species for discussion.

Throughout the tropics of the Western Hemisphere; from sea level to 2,200 m elevation. In Panama, known from tropical moist forest in the Canal Zone, Bocas del Toro, Los Santos, Panama, and Darién and from pre­montane wet forest in Colon and Chiriqui.
