DESCRIPTION:--_Corm_ 2·5 cm. in diameter, almost spherical, sending out lateral rhizomes. _Leaves_ arranged up the stem in a fan-like manner, 6 to 7 on each side, up to 30 cm. long, ·8 to 1 cm. broad, linear, acute, equitant at the base, with the midrib prominent and the lateral veins evident in fresh specimens, glabrous. _Peduncle_ up to 25 cm. long, 7-to 10-ribbed (almost narrowly winged), glabrous. _Inflorescence_ a lax panicle of 3 to 4 spikes. _Spikes_ 4 to 5 cm. long, 4-to 6-flowered. _Spathe-valves_ 8 mm. long, ovate, acuminate, brown, membranous. _Perianth-tube_ 1·5 cm. long, 4 mm. in diameter above, gradually narrowing below; lobes 2·8 cm. long, 9 mm. broad, oblong, obtuse, somewhat unequal. _Stamens_ fixed in the upper portion of the perianth-tube; filaments 2·2 mm. long, terete; anthers 8 mm. long, linear, versatile. _Ovary_ 6 mm. long, ellipsoid; style 3 cm. long, terete; style-branches 1 mm. long, bifid and papillose at the apex. _Fruit_ 9 mm. in diameter, globose, obtusely 3-angled, several seeds in each cell (National Herb. 2848). * * * * * PLATE 152.--Fig. 1, corm showing rhizomes; Fig. 2, median longitudinal section of a flower; Fig. 3, spathe-valves; Fig. 4, stamen; Fig. 5, upper part of style; Fig. 6, fruits.

Cap._ vol. i. p. 348. * * * * * This beautiful little _Oxalis_ belongs to a small group of about eight species which are characterised by having the leaves digitately 5-to 19-foliate, and in some respects these species are more showy than many of the others. The genus as a whole is essentially characteristic of the south-western portion of the Cape Province, but scattered species are found in various parts of the Union. Species of _Oxalis_ are also abundant in South America, where some of them form tall shrubs. Heterostylism, _i. e._ the different relative lengths of the stamens and styles, is found in the genus. In some flowers the styles exceed the stamens, while in others the stamens are longer than the styles. This arrangement of the sexual organs ensures that cross-pollination will take place. Our plate was prepared from specimens grown at the Division of Botany, Pretoria, from corms presented by Dr. C. L. Leipoldt, who collected them at Pakhuis in the Clanwilliam Division. According to Dr. Leipoldt the corms are edible.
