DESCRIPTION:--An herbaceous plant with erect stems, sometimes 6 ft. high, simple or branched. _Stems_ obtusely 4-angled, glandular-pilose. _Leaves_ opposite, sometimes alternate, petiolate; petioles 0·5-5 cm. long, grooved above, convex beneath, glandular-pilose; lamina 2-6·5 cm. long, ovate, more or less 3-lobed with the lobes crenate (the uppermost leaves not lobed), cordate at the base, palmately veined, with the veins prominent beneath, depressed above, glandular-pubescent. _Flowers_ solitary, axillary, with often two abortive flowers in the same leaf-axil. _Pedicels_ 5 mm. long, terete, glandular-pilose. _Calyx_ divided almost to the base; the lobes erect, 0·8-1 cm. long, lanceolate, acuminate, sub-obtuse, glandular-pilose; the anterior lobe the smallest. _Corolla-tube_ 3·5 cm. long, ventricose at the base, then slightly constricted and widening into a broad campanulate portion 1·4 cm. diameter, glandular-pilose; lobes 0·8 cm. long, about 1 cm. broad, transversely oblong, rounded above; the posterior lobe longer. _Stamens_ of two different lengths, inserted above the ventricose portion of the corolla-tube; filaments 0·9-1·3 cm. long, glabrous; anthers 5 mm. long, linear. _Ovary_ 6 mm. long, oblong in outline, densely villous, with 2 divergent horns at the apex; style 1·8 cm. long, terete, glabrous; stigmas recurved, papillose. _Fruit_ 2 cm. long, oblong, with 2 divergent horns, glandular-pilose.

Plant._ vol. ii. p. 492. =Dicoma Zeyheri=, _Cass. in Linn._ vol. xxiii. p. 71; _Fl. Cap._ vol. iii. p. 518. The genus _Dicoma_ comprises a small group of half-woody shrubs with acuminate usually pungent involucral-bracts. About twenty-five species are known, most of which are found in Tropical and South Africa, one extending into Western India. There is also a peculiar species, _D. cana_, in the island of Socotra. The tribe _Mutisieae_, to which _Dicoma_ belongs, is but sparingly represented in Africa and has its head-quarters in South America. Our present plant is common in parts of the Transvaal Highveld, and is found in flower from January to March. It has also been collected at Barberton by Mr. E. E. Galpin. Like so many of the shrubby plants occurring in the grass-veld, it has deep underground roots from which the stems arise, but, unlike the majority of them, is one of the last to flower. The specimen from which this plate was prepared was collected by Miss S. Gower near the Botanical Laboratories, Pretoria. Specimens are preserved in the National Herbarium, Pretoria (No. 2581).
