Description
editThe type specimen were collected at Goenoeng Warmijin, Java.[4]
Peperomia hirticaulis is an epiphytic plant with a hirsute stem, simple, terete, rooting at the base, with the terminal spike about 12 cm long, up to 1.5 mm thick. The leaves are opposite with very short glabrous petioles 1 mm long; the blade is elliptic-lanceolate, acute at both base and apex, up to 2 cm long and 4 cm wide. The peduncles are axillary and terminal, much exceeding the petioles, up to 13 mm long. The spikes are much longer than the leaves, up to 5 cm long and 2 mm thick, densely flowered, glabrous. The bract has an orbicular pelt, shortly pedicellate at the center, 0.5 mm in diameter. The ovary is glabrous, obovate, immersed in the rachis at the base, bearing a stigma at the very apex; the stigma is glabrous. The berry is subglobose, roughened with glands, nearly 1 mm in diameter.[4]
Taxonomy and naming
editIt was described in 1920 by Casimir de Candolle in the Annuaire du Conservatoire et du Jardin botaniques de Genève, from specimens collected by Henry Ogg Forbes.[5] The epithet hirticaulis refers to the hairy stem.[4]
