Peperomia pubirhachis is a species of epiphyte in the genus Peperomia that is endemic in Colombia. It grows on wet tropical biomes. Its conservation status is Threatened.
The type specimen where collected in San Francisco, Colombia.
Peperomia pubirhachis is a medium-sized, creeping, ascending herb with stems and petioles red when living. The stem is 4 mm thick below, ascending to 20 cm or more, with internodes 1âÂÂ3 cm long, densely covered with soft white hairs up to 2âÂÂ3 mm long. The alternate leaves are round-ovate, measuring 4âÂÂ7 cm wide by 4.5âÂÂ8 cm long, with obtuse apex and cordate base, densely appressed-hairy on both sides and fringed with hairs along the margin. They are palmately 9-nerved with the laterals moderately forked upward, drying dark and somewhat opaque. The petioles reach up to 8 cm long and are densely hairy. The spikes are young at the time of description, 8 cm long, terminal and in the axils of much reduced leaves on sympodial branches 5âÂÂ8 cm long, moderately flowered. The peduncle is 5 cm long and hairy; the rachis is finely hairy. The bracts are round-peltate with red glandular dots. The ovary is govary with apical stigma. Fruit was not matured.
The densely villous stems and petioles with long white hairs up to 2âÂÂ3 mm, the long-petiolate round-ovate leaves (petioles up to 8 cm) that are densely appressed-hairy on both sides and ciliate, and especially the puberulent (finely hairy) rachis of the spikes set this species apart.
It was described in 1950 by Truman G. Yuncker in ', from specimens collected by GarcÃÂa Barriga. It got its name from description of the species, which literally translates to hairy rachis.
It is endemic in Colombia. It grows on a epiphyte environment and is a herb. In Colombia, its elevation range is 1550 meters. It grows on wet tropical biomes.
This species is assessed as Threatened, in a preliminary report.
