Syrrhopodon spuriodisciformis Dusén (Calymperaceae) as a distinct species, with taxonomic notes on Syrrhopodon africanus (Mitt.) Paris and related taxa

Abstract

Syrrhopodon spuriodisciformis Dusén is removed from synonymy with Syrrhopodon africanus (Mitt.) Paris and reinstated as a distinct species. Syrrhopodon guineensis Broth. & Paris is recognised as a synonym of S. spuriodisciformis. Syrrhopodon africanus ssp. graminicola (R.S.Williams) W.D.Reese and S. africanus ssp. mandrakensis (Tixier) W.D.Reese are reconsidered as species, and the status of Syrrhopodon obuduensis Egunyomi & Olar. is discussed.

Keywords:

• Calymperaceae
