This species was described from a leafless specimen and was considered by Mildbraed (loc. cit.) to be related to S. quinqueloba but, now we have more complete material, it is obviously more closely related to S. subviolacea.Tree up to 30 m. tall, with digitately compound leaves; leaflets 8–11, subsessile, lanceolate, glabrous or glabrescent. Flowers in terminal panicles, red or scarlet, smelling of carrion; calyx c. 1·25 cm. long, tomentose. Follicles ovoid, seeds large.Cultivated Species of BrachychitonThree other decorative trees cultivated in our area belong to an Australian genus closely related to Sterculia. One is Brachychiton acerifolium (A. Cunn.) F. Muell. (Sterculia acerifolia A. Cunn.), sometimes called the Flame Tree, from New South Wales. It is a glabrous tree up to 20 m. or more in height with deeply 5–7-lobed leaves, the lobes oblong-lanceolate to rhomboid, and with brilliant scarlet flowers. It is grown in the Municipal Gardens, Lourenço Marques, and in S. Rhodesia. A second is Brachychiton populneum (Schott) R. Br. (Sterculia diversifolia G. Don), the Kurrajong of Queensland and Victoria. It also reaches 20 m. in height, is glabrous except for the flowers and has ovate to ovate-lanceolate leaves which are entire or 3–5-lobed with slender petioles. The flowers are yellowish-white and often dark-spotted and may be reddish inside. This is grown as a street tree in the Rhodesias and Mozambique. Finally, there is Brachychiton discolor F. Muell. from New South Wales and Queensland, which is also cultivated in Lourenço Marques and Salisbury. It has 5–7-lobed broadly cordate-ovate discolorous leaves and carmine flowers, and reaches IS m. in height.
