Peperomia glabrirhachis

Peperomia glabrirhachis is a species of epiphyte 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 near Huancabamba, Peru.[4]

Peperomia glabrirhachis is a moderately small, stoloniferous, tufted herb. The stem is 1–2 mm thick, angled, and sparsely covered with retrorse hairs. The leaves are in whorls of about 4 at the nodes. They are somewhat rhombic-elliptic to obovate, obtuse, with an acute base, measuring 10 mm long and 5–6 mm wide. The leaves are 1-nerved, revolute, sparsely pubescent beneath, and have a papillose-rugose texture on both surfaces. The petiole is barely 1 mm long. The terminal spikes are 15 mm long and 1 mm thick, glabrous, and borne on a filiform, velvety peduncle about as long as the spike itself. The floral bracts are round-peltate.[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 Frank Lincoln Stevens.[5] The epithet glabrirhachis is derived from the Latin glaber and rhachis, referring to the glabrous flower spikes.[4]

Distribution and habitat

It is native to Peru.[2] It grows as a epiphyte and is a herb.[1][4] It grows on wet tropical biomes.[1]

Conservation

This species is assessed as Threatened, in a preliminary report.[3]
