Taxonomic account of Hemigraphis Nees (Strobilanthinae-Acanthaceae) from the Philippines

Abstract

A taxonomic account of Hemigraphis Nees from the Philippines is provided. A pattern-based species concept is adopted and 18 species of Hemigraphis from the Philippines are recognised. Six species have an extended distribution beyond the Philippine archipelago. Three species are archipelagic endemics and nine species are restricted island endemics. One new species, Hemigraphis zwickeyae, is described from the islands of Luzon and Mindanao
