Three new species and a new synonym in Strumaria (Amaryllidaceae: Amaryllideae) from southern Africa

Abstract

Newly described are three species of Strumaria Jacq. subgenus Strumaria. S. prolifera Snijman from the Kourkammaberg in Namaqualand, South Africa, is a rare species closely allied to 5.  barbarae Oberm. S. speciosa Snijman from the Sonberg, southern Namibia and S. luteoloba Snijman from Namuskluft, southern Namibia and the Richtersveld in Northern Cape, South Africa, are rare species closely related to  S. phonolithica Dinter.  S. gigantea D.Mull.-Doblies & U.Miill.-Doblies is formally presented as a new synonym of S.  phonolithica. A key to the species in Strumaria subgenus Strumaria is given.
