Cape to Queenstown. A. caffrum ocenis on rocks on the 

 Witteberg, and its Yarmtj naialensis-is a rare Natal mountain- 

 veld species. A. turgidulum is the commonest Eastern Grass- 

 veld species, chiefly in Mountain Veld. 



The species of Avenastrum are hard-leaved and xero- 

 phytic with strong ridges, very similar to the other temperate 

 species illustrated. 



Axonopus semialatus var. ecklonii. (See Fig. 1 E.) A 

 common Grassveld species of the Eastern side. It forms vernal 

 aspect societies. 



Brachypodium. B. distachyum is an introduced ruderal 

 species at the, Cape. B. holusii is a rare mountain species on 

 the Compass Berg, and the only other South African species 

 B. flexum, of which there are several varieties, extends from 

 Capetown to Natal. The variety simplex is a mountain type 

 usually in shade in the Drakensberg and other mountains of 

 Natal, occurring rarely at lower altitudes. 



Bi'iza. B. 'maxima and B. minor are both introduced 

 species widely distributed in South Africa, chiefly ruderal. 



Brizopyrum. (Temperate.) All the species are confined- 

 to the region of Macchia in the South West. They are all 

 rather rare except B. caj/ense, which is common and extends 

 as far east as Port Elizabeth. Its leaf in transverse section 

 is very similar to that of Achneria capensis, which has already 

 been described, (See Fig. 3.) All the species of Brizopyrum, 

 are xerophytic and deep rooted, and they grow rather sparsely 

 scattered. 



Bromus. (Temperate.) The four perennial species B. 

 leptoclados, B. natalensis, B. speciosus, B. firmior are mostly 

 mountain types, though B. Ifptaclados occurs in the Cape 

 Peninsula also, and B. natalensis is recorded for Weenen in 

 Natal. None of them are common, as far as I have seen. 

 The half-dozen annuals are weeds, probably all introduced. 

 The leaves have low ridges and only the larger bundles are 

 girdered. 



Calamagrostis epigeios var. capensis differs very slightly 

 from the European form. It occurs at the foot of the 

 Witteberg, and in Griqualand West. The leaves have pro- 

 minent ridges, and the vascular bundles are strongly girdered 

 with sclerenchyma. 



Chaetobromus. Ch. schraderi is only recorded for 

 Paarden Island, and Ch. involucratus, and Ch. dregeanus are 

 from Little Namaqualand. They are tufted xerophytic forms.
