Four new species of Aspalathus (Fabaceae, Crotalarieae) and notes on three rediscovered species from the Greater Cape Floristic Region

Abstract

We describe four new species from the Western Cape, South Africa. Aspalathus strigosa Du Preez & C.H.Stirt. is only known by the type collection from the southern slopes of the Klein Swartberg Mountains near Ladismith. Aspalathus albomagnifica Du Preez & C.H.Stirt. is a white-flowered species from lowland renosterveld and fynbos from Hartenbos on the Garden Route. Aspalathus jardinii Du Preez & C.H.Stirt. is a habitat specialist growing in sand dunes of the Riet River running through the Swartruggens Mountains. Aspalathus albicephala Du Preez & C.H.Stirt. is an attractive, critically endangered species from the rooibos belt on Gifberg Mountain. Notes are also provided on three recently rediscovered taxa that were believed to be extinct, Aspalathus cordicarpa R.Dahlgren, A. compacta R.Dahlgren and A. complicata (Benth.) R.Dahlgren. Composite photographic plates, distribution maps, details of habitat, ecology and conservation status are provided for all species.
