Peperomia subpetiolata, commonly referred to as Ala Ala Wai Nui or Waikamoi peperomia, is a species of shrub in the genus Peperomia that is endemic in Hawaii.[1][2] It grows on wet tropical biomes.[1] Its conservation status is Threatened.[3]
Description
The first specimens where collected in Caldas, Colombia.[4]
Peperomia sneidernii is an erect to decumbent herb that roots at the base, reaching up to 8 cm tall. The stem is 1 mm in diameter, unbranched, smooth and hairless, with internodes 3–4 cm long above, lengthening to 12 cm below. The leaves are arranged in whorls of 5 to 8, somewhat fleshy, linear-oblong to lanceolate, up to 3.5 cm broad and 16 cm long, with 5 main veins, the midrib forking in the lower 2–4 cm, and long-tapering apices. The base is wedge-shaped and essentially sessile or with a blade forming wings along a very short stalk. The upper surface is smooth with scattered glandular dots, while the underside is densely covered with fine white hairs when young, becoming hairless with age, and marked with impressed glandular dots. The terminal and axillary spikes are up to 10 cm long and 3 mm thick, densely flowered, on peduncles reaching 3.5 cm. The smooth, hairless rachis has bracts about 6 mm broad. The filaments are longer than the ellipsoid anthers, and the ovary is top-shaped with a stigma that is apical, inconspicuous, and divided.[4]
Taxonomy and Naming
