Mr. T. P. Stokoe, to whom we are indebted for so many of the interesting plants figured in earlier plates of this work, has again contributed two exquisite species of _Mimetes_ which are both undescribed. Unfortunately, it was not possible at the time to figure both plants, but we hope to publish a figure and description of the second species in our next volume. The genus, which is represented by nine species, falls into two well-defined groups, (_a_) those with an ovoid stigma (represented by _M. capitulata_, figured on Plate 58) and (_b_) those species with a linear stigma (represented by _M. palustris_, figured on Plate 36). Hitherto only two species of the first group were known, but these recent acquisitions from Mr. Stokoe increases this number to four. The species figured in the accompanying plate was found on the Hottentot’s Holland Mountains S.E. of Kogelberg and was growing on the banks of a steep, fairly moist slope. When fresh, it is a most beautiful object, certainly one of the most handsome species of the genus. The styles are bright red, white just below the stigma, and the stigma brownish-black. It is characterised by the regular excavations on the surface of the stigma which appear to be receptacles for the pollen grains. Specimens are preserved in the National Herbarium, Pretoria (Herb. No. 1641). DESCRIPTION:--_Branches_ minutely tomentose but also sparsely covered with long lax hairs. _Leaves_ 4·5-7·5 cm. long, 2·2-3·5 cm. broad, elliptic, with a blunt 3-toothed callous apex, densely adpressed-pubescent with silky hairs. _Heads_ sessile, 7·5 cm. long including the styles, 8-12-flowered, solitary in the axils of the leaves at the ends of the branches. _Involucral-bracts_ 3-seriate; the outer 1·7 cm. long, 6 mm. broad, lanceolate-ovate, obtuse, villous without, long-ciliate; inner 2 cm. long, 3 mm. broad, linear or linear-lanceolate, sub-acute, villous without, long-ciliate. _Receptacle_ villous. _Perianth_ divided almost to the base; segments 3·2 cm. long, linear-filiform, slightly broadened at the base, villous; limb 6 mm. long, obovate, subacuminate, obtuse, villous. _Anthers_ sessile, 2·5 mm. long, obtuse. _Hypogynous scales_ 3 mm. long, linear subacute. _Ovary_ about 1 mm. long, hairy at base; style 6·5 mm. long, cylindric, glabrous; stigma 4 mm. long, obovoid, obtuse, with several depressions on the sides.
