Peperomia exilamenta is a species of epiphyte in the genus Peperomia that is endemic in Peru.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]
The type specimen were collected near Tarapoto, Peru at an altitude of 360-900 meters.[4]
Peperomia exilamenta is a rather large, epiphytic or terrestrial herb. When dry, the stem is 3–4 mm thick, deeply angled, and very sparsely covered with soft, minute bristles. The leaves are typically in whorls of 3. They are broadly lanceolate to elliptic-lanceolate, bluntly acuminate, with an acute base, measuring 5–6 cm long and 2–2.5 cm wide. They are 3-nerved, with the nerves impressed above and prominent beneath. The leaves are glabrous, with impressed-punctulate dots on the upper surface, a revolute margin, and are very rigid. The petiole is 5 mm long and puberulous. The spikes are terminal and from the upper axils, 120 mm long and 1 mm thick, borne on a peduncle 10–25 mm long. 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 Llewelyn Williams.[5] It got its epithet from the Latin wikt:exilis + wikt:amentum, referring to the slender spikes or the thin, strap-like leaves.
