Portulaca psammotropha Hance (Portulacaceae), a Neglected Species in the Flora of Taiwan and the Philippines

A neglected species in the Flora of Taiwan and the Philippines (the Batan islets), Portulaca psammotropha Hance, is described and illustrated. Herein, Portulaca quadrifida var. formosana and P. insularis are treated as synonym of P. psammotropha. This species is a typical littoral plant that is scattered on coral sands and coral reef in the archipelago around SE China. It can be characterized by leaves alternate; leaf blade quite fleshy, oblong to obovate-oblong, 3-10mm long, apex obtuse; petals 5, yellowish, ca. 3-5mm long. The stamen number and stigma lobes of this species vary among the populations observed.
