The species of _Aloe_ figured on the accompanying plate belongs to the less conspicuous members of the genus. The small cream-yellow flowers do not make the inflorescence very attractive. _Aloe sessiliflora_ was collected in the Barberton District by Mr. J. E. Wickens, and flowered at the Union Buildings for the first time in June and July of 1914. Mr. Geo. Thorncroft subsequently collected the plant near Barberton. During the winter months the leaves are of a distinct reddish colour, while in summer they are bright green. The flowers contain drops of very dark nectar at the base of the perianth. Our plate was made from specimens growing at the Division of Botany, Pretoria. DESCRIPTION:--_Stem_ up to 90 cm. high. _Leaves_ in a dense rosette at the apex of the stem, 45 to 60 cm. long. 6 to 8 cm. broad, spreading or recurved, fleshy, channelled above, convex beneath, with the margins toothed. _Peduncle_ simple, 60 to 75 cm. long, laterally compressed, covered with numerous oblong brown bracts. _Spike_ densely many-flowered, more or less cylindric; bracts 10 mm. long, 7 mm. wide, ovate-cuspidate, 3-nerved. _Flowers_ campanulate-cylindric; perianth 14 mm. long; segments free; the outer 5 mm. broad, spathulate, fleshy-coloured with three longitudinal dark nerves; the inner 8 mm. broad, yellowish at the edges and with a reddish or greenish median line. _Stamens_ and _style_ protruding 8 to 10 mm. beyond the perianth. _Capsule_ 9 to 10 mm. long, cylindric-oblong, enclosed in the dry peri-anth. _Seeds_ 3 mm. long, three-angled, greyish, very narrowly winged.

STAPELIA GIGANTEA var. PALLIDA. _Transvaal (?)._ ASCLEPIADACEAE. Tribe STAPELIEAE. STAPELIA, _Linn._; _Benth. et Hook. f. Gen. Plant._ vol. ii. p. 784. * * * * * =Stapelia gigantea=, _N.E. Br._ var. =Pallida=, _Phillips_ var. nov., a typo corolla depressiore differt. * * * * * The _Stapelia_ figured on the accompanying Plate is very near _S. gigantea_, N.E. Br., from which it differs, however, in having the disc portion of the corolla more depressed and being much lighter in colour. It appears to be an intermediate form between this species and _S. nobilis_, N.E. Br., differing from the latter species in not having such a cup-shaped corolla-disc and not having the lobes of the outer corona 3-toothed. The locality in which the plant is found is not known, and the specimen from which our Plate was prepared was kindly presented by Dr. A. J. T. Janse, who grew it in his rockery.
