The amount of sclerenchyma is not excessive. Eriaiithus. E. capensis, E. sorghum are both tall Vlei species, sometimes also transitional to Bush. Both are known as umTala. E. junceus is a Basutoland and Eastern Mountain species. The umTalas are about the tallest of our South African grasses, growing up to 15 feet or more. They are used for Pie 14.âTransverse Section of a portion of a leaf of Eragrostis curvula (X about 60). Festuca (See Fig. 1 A. and B.) is a temperate Mountain i genus of the Ea chiefly, but E. scahra, Yeld ffenus of the Eastern and South Central Mountain ranges South Africa. It grows in isolated tufts. which is dioecious, occurs all over F. caprina (bok baard) is dominant over stretches of Mountain Veld, and is reckoned rather a good pasture grass. It is fairly common in Natal (though no records are given in the Flora Capensis), and it extends along the Drakensberg to the Stormberg and Amatolas. F. costata is similar in its distribution and even commoner, but rarely dominant. F. Inncjipes is rare and F. â vulpioides is only recorded from the Amatolas. The species grow in dense tufts or they form hard tussocks. F. caprina â is the most xerophytic, with permanently folded filiform or setaceous leaves, and a contracted panicle. The leaves all show more or less prominent ridges in cross Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and
