Notes
Nees quotes numerous other localities, partly under E. filiformis, partly under E. curvula, from which I have not seen any specimen. As they come, however, entirely within the area indicated by the localities cited above, and as I am not certain as to the variety under which I should have to enumerate them, I preferred omitting them altogether. Drège's specimen from Paarl Mountain, mentioned above, was distributed as Eragrostis capillifolia, Nees. Nees described this plant from Paarl Mountain, and does not mention any other locality; but the description in Nees, Fl. Afr. Aust. 403, does not agree with Drège's specimen, named E. capillifolia in the Kew Herbarium, as Nees described his plant as having hairy lower and scabrid upper internodes, a pyramidal panicle with a very scabrid axis and similar spreading branches. Nevertheless, I am convinced that this species as well as E. subulata, Nees (l.c. 399), from the Gauritz River and the Lange Kloof which I have also not seen, are but states of E. curvula.
