摘要
Nematostylis Hook. f. (Rubiaceae) is a genus of semi-succulent shrubs endemic to Madagascar, mostly found growing on rocky outcrops in the Northern, Central, and Southern Highlands. This paper provides a revision of the genus in which three species are recognized: N. anthophylla (A. Rich. ex DC.) Baill. and the newly described N. citriflora Kainul. and N. incarnata Kainul. An identification key of the genus is presented, as well as a distribution map, field pictures, line drawings, and species risk of extinction assessments. A neotype is designated for N. anthophylla and a lectotype for N. loranthoides Hook. f.
