Information
Very similar to the typical form, but smaller in all parts, apparently forming dense cushions of leafy branches 3–6 in. high, from which the flowering culms rise for another 6–12 in. Leaf-blades usually 3/4–2 in. by 1 to almost 2 lin., often almost pungent, with straight rarely slightly wavy finely scaberulous margins, with or without more or less distant and very minute spinules. Inflorescence 1–2 in. long. Spikelets from less than 1 to 1 1/4 lin. long.

Notes
This variety is perhaps only an edaphic or climatic modification of typical B. serrata. Very similar states were collected by Schlechter (no. 1721, distributed as Panicum serratum f. minor), and Burchell in Riversdale Division and by the latter also in Mossel Bay Division (Cape of Good Hope).
