Peperomia subflaccida

Peperomia subflaccida is a species of epiphyte in the genus Peperomia that is endemic in Peru.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]

Description

The first specimens where collected in Loreto, Peru.[4]

Peperomia subflaccida is a small, somewhat floppy, creeping herb that roots from its lower nodes. The stem is smooth and hairless, measuring 1–2 mm in diameter when dry, with branches ascending to about 10 cm; the upper internodes are short, lengthening downward. The alternate leaves are egg-shaped with pointed tips and heart-shaped bases, smooth beneath, with a few soft but thick white hairs above; the margin has distant fine hairs with short stiff tips. Leaves are 1–2 cm wide and 1.5–4 cm long, palmately 7-nerved with nerves branching upward, red-glandular-dotted beneath when young, drying thin, somewhat translucent, dark above and pale beneath. The petiole is 1–1.5 cm long, becoming nearly absent on upper leaves. Terminal spikes are 1 mm in diameter and 1.5 cm long, green when growing, on peduncles about 3 mm long; bracts are rounded and somewhat spoon-shaped, glandular-dotted. Fruit is egg-shaped with a conic tip and apical stigma.[4]

The combination of its delicate, floppy growth form except for scattered soft white hairs on the upper leaf surface sets this species apart. The leaves are distinctly egg-shaped with heart-shaped bases, measuring 1.5–4 cm long, and display seven radiating veins with red glandular dots visible on the underside when young. Most notably, the fruit is egg-shaped with a conic projection at the apex, a feature reflected in the species name. These characteristics distinguish it from P. hispidula, which shares similar leaf hairs but differs markedly in other features.[4]

Taxonomy and naming

It was described in 1957 by Truman G. Yuncker in Svensk Botanisk Tidskrift 51, from specimens collected by Guillermo Klug.[5]

Distribution and habitat

It is endemic in Peru.[2] It grows on a epiphyte environment and is a herb.[1][4] It grows on wet tropical biomes.[1] The first specimens were collected at and altitude of 600-1200 meters. [5]

Conservation

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