Gerbera leucothrix Harv. in Harv. & Sond. in Fl. Cap. 3: 521 (1865), syn. Nov. Type: South Africa, Western Cape Province, Bredasdorp (3420): ‘Zwellendam, trockene Bergrücken, bei Stormvalei, Hassaquaskloof bis Breederivier’, (− AA), Ecklon & Zeyher (S [S1012,093], holo.—image!). [Note: Harvey (1865) based his name on a solitary specimen from between Riviersonderend and Swellendam, and raised the possibility that it might represent a hybrid between G. crocea (as G. burmanni ) and G. serrata (as G. ferruginea ), combining the sinuately incised and rufous-felted foliage of the latter with the multi-seriate involucre and white pappus of the former, but Hansen (1985) suggested that it might rather be associated with collections of plants that he identified as of hybrid origin G. crocea × G. tomentosa from between Paarl and Montagu. However, the deeply retrorsely incised-sinuate leaf margins and yellowish-grey felted underside of G. leucothrix are quite consistent with G. tomentosa , which it also matches in its imbricate involucres and whitish pappus. Gerbera tomentosa has been recorded from the Riviersonderend and the Langeberg at Swellendam and we see no reason not to accept that the two are the same, and accordingly place G. leucothrix in synonomy.]
