"Haemanthus pubescens" ('pubescens': Latin 'having a soft downy covering') is an endemic South African bulbous geophyte belonging to the Amaryllidaceae.

The plant was first described by Linnaeus in 1781, 19 years after his description of "H. coccineus". Both species are common along the West Coast and it is puzzling that "H. pubescens" was not collected and described much earlier. The genus "Haemanthus" was created in 1753 by Linnaeus. In 1838 the eccentric Constantine Samuel Rafinesque, placed "H. pubescens" in a new genus "Leucodesmis", "H. coccineus" in "Perihema", and "H. carneus" in "Serena". The troubled English botanist Richard Anthony Salisbury (1761-1829) in his 1866 posthumous publication 'Genera of Plants', placed "H. amarylloides" under "Melicho" and "H. albiflos" under "Diacles".

"H. pubescens" occurs at elevations up to 300 m from Cape Town northwards along the coast to southern Namibia. Formerly it was known only from the south western Cape, but collections from north of the Olifants River into Namibia, led to a revision of its geographic limits. The 4-7 large, fleshy spathe valves are diagnostic of the species. The two leaves are broad, flat on the ground and usually pubescent. Bulbs are deep, with fleshy distichous tunics.
