Peperomia pubirhachis is a species of epiphyte in the genus Peperomia that is endemic in Colombia.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]
Description
The type specimen where collected in San Francisco, Colombia.[4]
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 1–3 cm long, densely covered with soft white hairs up to 2–3 mm long. The alternate leaves are round-ovate, measuring 4–7 cm wide by 4.5–8 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 5–8 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.[4]
The densely villous stems and petioles with long white hairs up to 2–3 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.[4]
Taxonomy and naming
It was described in 1950 by Truman G. Yuncker in The Piperaceae of northern South America 2, from specimens collected by García Barriga.[5] It got its name from description of the species, which literally translates to hairy rachis. [4]
Distribution and habitat
It is endemic in Colombia.[2] It grows on a epiphyte environment and is a herb.[1][4] In Colombia, its elevation range is 1550 meters.[1] It grows on wet tropical biomes.[1]
Conservation
This species is assessed as Threatened, in a preliminary report.[3]
