78 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 9, No. 1 



tinct species, Australina thunbergii N.E.Br. The true Urtica capensis L.f. is, 

 according to Prain in Thiselton-Dyer, Fl. Cap. 5 2 : 473 (1920), not urticaceous at 

 all, but a species of Acalypha (Euphorbiaceae). 



N.E. Brown in the Flora capensis realised that Fleurya capensis could not 

 be used, but unfortunately adopted instead Fleurya mitis Wedd., a nomen nudum 

 not previously validated. The only legitimate name available seems to be F. 

 peduncularis Wedd., which I therefore adopt. 



To sum all this up: three species are involved. 



(1) Urtica capensis L.f. (1781) = Acalypha sp. 



(2) Urtica capensis (non. L.f.) sensu Thunb. (1794, 1813) = Fleurya capensis 

 Wedd. (1854) = Australina capensis (non Wedd.) sensu N.E. Br. (1913) = Australina 

 thunbergii N.E. Br. 



(3) Fleurya capensis (non. Wedd. 1854) sensu Wedd. (1856-7) = Fleurya mitis 

 Wedd. ex N.E. Br. = Fleurya peduncularis Wedd.
