They are tropical in their affinities and occur also in Tropical Africa. They only rarely assume dominance anywhere in climax Grassveld, being easily ousted by other grasses. Ch. petraea is perennial and flowers early, the others are annual or sub-perennial and flower late. If the Veld grass is burned before they have time to seed they are easily.

Other aspects of the sanie subject will be discussed at length later. Fig. 7 shows the cross section of a leaf of CJi. gtn/ana. The chlorophyll tissue is confined to a ring round the vascular bundles. The whole ujjper half of the leaf consists of water storage tissue, which is free from chlorophyll. There is a distinct midrib, and the leaf folds conduplicate as it dries. There is very little sclerenchyma below each bundle, but tlie margins of the leaf (see right hand side of the figure) are more strongly fibrous and slightly thickened. Crossotropis (jraiKliglnmis is a very distinctive species- with spikelets distant from each other along the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bews, J.
