Peperomia latilimba 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 was collected in Tambo, Colombia.
Peperomia latilimba is a terrestrial, succulent herb with a stem 10 mm or more thick at the base, reaching up to tall, somewhat finely hairy above and becoming hairless downward, with internodes 2âÂÂ6 cm or more long. The alternate leaves are broadly round-ovate, measuring 9âÂÂ10 cm wide by 10âÂÂ11 cm long, with acute apex and shallowly cordate base. They are 13-plinerved, with the midrib branching within the lowermost 3 cm, finely hairy on the nerves near the base above, hairless beneath or slightly finely hairy on the nerves at the base, and fringed with fine hairs along the margin. The leaves dry membranous and translucent. The petioles are 5.5âÂÂ9 cm long and somewhat finely hairy. The spikes are 3âÂÂ4 mm thick by 10âÂÂ17 cm long, 2 or 3 on a common, sympodial, finely hairy stalk 5âÂÂ8 cm long, on peduncles 1âÂÂ2 cm long that are velvety-puberulent. The bracts are round-peltate. The fruit is ellipsoidal with a beak, about 1 mm long including the acute beak, with stigma anterior at the base of the beak.
The combination of its large, rounded, cordate leaves (10âÂÂ11 cm long and nearly as wide) with 13 main veins, the rather long petioles (5.5âÂÂ9 cm), and multiple spikes (2 or 3) on sympodial stalks 5âÂÂ8 cm long characterize this species. It sets apart from P. multiplinervia, which has similar leaf shape and size but differs in being 13-plinerved and hairy along the nerves
It was described in 1950 by Truman G. Yuncker in ', from specimens collected by Oscar Lee Haught. It got its name from the description of the type specimen.
It is endemic in Colombia. It grows on a epiphyte environment and is a herb. In Colombia, its elevation range is . It grows on wet tropical biomes.
This species is assessed as Threatened, in a preliminary report.
