Abstract

Hymenolepis glabra Magoswana & Magee (Asteraceae, tribe Anthemideae) is a new species from the Little Karoo, within the Greater Cape Floristic Region of South Africa, bringing the number of recognised species in the genus to nine. The species shares the glabrous involucre and open, doubly compound corymbs with H. crithmifolia and H. indivisa but is distinguished by the erect to suberect, 2- or 3-sect leaves, entire towards the synflorescence, and the complete lack of vestiture. The new species is described, and the existing key to the species is updated.
