Urtica urentivelutina

Urtica urentivelutina is a species of the genus Urtica. This species is closely related to U. macbridei, but differs in its much denser and longer indument, especially on the stipules (subglabrous in U. macbridei) and the presence of stinging hairs on the perigon of the female flowers. The leaves are densely pubescent and also irregularly bullate between the veins, which is a character not found in other Peruvian species.

Description
Its liana is 35 m tall from a ligneous rhizome approximately 810 mm thick. Its stems are lax, with scattered stinging hairs between 1.5 and 2 mm long and with a dense, white cover of simple trichomes 11.5 mm long. Leaves are opposite, with interpetiolar stipules united in pairs but deeply incised, and completely covered with white simple trichomes appromately 0.51 mm in length. Petioles are 24 cm long, and its cystoliths are largely punctiform. Inflorescences are unisexual, while its fruit is ovate, approximately 1.5 mm x 1 mm, with a very short apex, largely included in the pubescent perigon.

Distribution
La Libertad, Sánchez Carrión Province. It is found in the remnants of cloud forest vegetation.
