Peperomia perglandulosa is a species of epiphyte in the genus Peperomia that is endemic in Colombia & Panama.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]
Description
The type specimen where collected near El Valle de Antón, Panama at an altitude of 1100 meters.[4]
Peperomia perglandulosa is a creeping, succulent epiphytic herb with a stem 2 mm thick, densely covered with red hairs, rooting at the nodes, with internodes 2–5 cm or more long. The alternate leaves are deltoid-ovate with rounded apex and truncate base, mostly subpeltate with the petiole attached 1–2 mm from the margin, measuring 1.5–3 cm wide by 1.5–3 cm long. They are palmately 5-nerved with slender, obscure laterals, nearly hairless above, covered with fine hairs beneath at least along the midrib, with margin densely fringed with hairs and a zone of submarginal hairs on the upper surface. The leaves dry rather thick and opaque, densely and conspicuously red-glandular-dotted on both sides with comparatively large glands. The petiole is 1.5–4 cm long, densely red-hairy and sparsely red-glandular. The leaf-opposed spikes are 2 mm thick by 7 cm long, densely flowered, on peduncles 2.5 cm long that are densely red-hairy with scattered red glands and bracteate near the middle. The floral bracts are round-peltate, conspicuously and densely red-glandular. The ovary is ellipsoidal, red-glandular, sharply beaked, with stigma anterior at the base of the beak. Fruit was not present.[4]
The densely red-villous stems and petioles, together with the conspicuously and densely red-glandular leaves, bracts, and ovary distinguish this species.[4]
Taxonomy and naming
It was described in 1950 by Truman G. Yuncker in Annals of the Missouri Botanical Garden 37, from specimens collected by Paul H. Allen.[5] It got its name from description of the species, which literally translates to very glandular. [4]
Distribution and habitat
It is endemic in Colombia & Panama.[2] It grows on a epiphyte environment and is a herb.[1][4] In Colombia, its elevation range is 1250–2010 meters.[1] It grows on wet tropical biomes.[1]
Conservation
This species is assessed as Threatened, in a preliminary report.[3]
