Peperomia polycephala is a species of terrestrial or epiphytic herb in the genus Peperomia that is native to Peru.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]
Description
The type specimen were collected at Aina, Peru at an altitude of 700-1000 meters above sea level.[4]
Peperomia polycephala is a small, glabrous, stemless herb. The leaves arise from the apex of a thick, compactly branched rhizome. They are orbicular, peltate toward the center, measuring 2–4 cm wide, and are thin when dry. The petiole is 5 cm long or more. The spikes are filiform, 90–100 mm long, with a very slender peduncle nearly equaling the petiole. The berries are ellipsoid-ovoid with a slender basal projection supporting the style, and have an apical stigma.[4]
Taxonomy and naming
It was described in 1936 by William Trelease in Publications of the Field Museum of Natural History, Botanical Series 13 (es), from specimens collected by Ellsworth Paine Killip & Albert Charles Smith.[5]
The epithet is derived from the Greek poly and kephalē, meaning "many-headed," referring to the numerous flower spikes emerging from the compact, many-branched rhizome apex.[4]
Distribution and habitat
It is native to Peru.[2] It grows as a terrestrial or epiphytic herb.[1] It grows on wet tropical biomes.[1]
Conservation
This species is assessed as Threatened, in a preliminary report.[3]
