Peperomia quadratifolia 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 Schunke Hacienda, Peru at an altitude of 1400-1700 meters above sea level [4]
Peperomia quadratifolia is a small, creeping, epiphytic herb that is transiently more or less pilose at the nodes, with a filiform, rooting stem. The leaves are in whorls of about 4 at the nodes. They are rhombic-square, bluntly subacuminate, with an acute base, and are 1-nerved, drying to an opaque green. The terminal spikes are filiform, 40 mm long, with a 20 mm peduncle. The rachis is glabrous with somewhat loosely arranged flowers. The berries are ovoid, pointed, and bear a pseudocupula, with 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, from specimens collected by Ellsworth Paine Killip & Albert Charles Smith.[5]
The epithet combines the Latin quadratus and folia, referring to the distinctive square or rhombic-quadrate shape of the leaves.[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]
