Abstract
A new species of Capparis, Capparis hinnamnoensis, is described from the Khammouan Province, central Lao PDR. The new species is characterized by the indumentum constituted by stellate, two-armed and simple hairs, and by the terminal racemes bearing trifid bracts and medium-sized flowers. It is so far known from a single locality in the Hin Nam No National Protected Area, where it has been observed in the deciduous forest on Permo-Carboniferous limestone. Its conservation status is assessed.
