The species here figured belongs to a small group of species in the genus (Section _Scandentes_), which is characterised by its members being climbing, half-climbing or trailing plants. _Senecio tamoides_ is a very common plant in the bush and the coastal belt, and its large trusses of bright yellow, honey-scented flowers show up in strong contrast against the background of dark green foliage. At Durban, Natal, the flowers are frequently attacked by an insect, and as a result a gall is formed inside the flower head. The gall enlarges into a cylindric green body much longer than the flower-head, and each contains a single larva. _Senecio tamoides_ has been recorded from the Chipete Forest in Rhodesia, and was also collected by Mr. E. E. Galpin, F.L.S., at Barberton in the Transvaal. Our illustration was made from specimens collected by Miss K. A. Lansdell on the Berea, Durban. DESCRIPTION:--A climbing herb. _Branches_ glabrous. _Leaves_ 2·2 to 5·5 cm. long, 2·7 to 6 cm. broad, ovate, acuminate, subobtuse, somewhat hastate, with the margins acutely lobulate, glabrous. _Inflorescence_ a many-headed corymb. _Involucral-bracts_ about 6, 8 mm. long, 2 mm. broad, oblong-linear, obtuse, with membranous margins. _Ray-florets_: _Tube_ 5 mm. long, cylindric; limb 6·5 mm. long, 2 mm. broad, oblong. _Style_ exserted; style branches filiform. _Disc-florets_ male, cylindric, 6·5 mm. long, lobes ·75 mm. long, linear, obtuse. _Anthers_ blunt. _Style-branches_ linear, truncate. _Ovary_ infertile, 3 mm. long, cylindric, ribbed, glabrous. _Pappus_ copious.

The species is readily raised from seed, and under proper cultivation it flowers about fifteen months after sowing. Our plate was made from plants grown by Dr. I. B. Pole Evans, C.M.G., at Irene near Pretoria.
