The specimen from which the present plate was prepared flowered at Pretoria in August, and has enabled us to draw up a more complete description. Specimens are preserved in the National Herbarium. DESCRIPTION:--A stemless plant. _Root_ thick and woody. _Leaves_ tufted, 8-12 in a cluster, forming a rosette about 9 cm. in diameter, 3-5·5 cm. long, 1-1·7 cm. broad in the widest part, lanceolate-spathulate viewed from above, acuminate, obtuse, mucronate at the apex and shaped like the bow of a boat, slightly narrowed at the base and sheathing, flat above, keeled beneath, dotted with white spots on both surfaces. _Flowers_ lemon-yellow, sessile between the leaves. _Calyx-tube_ 2·2 cm. long, widening from a cylindrical base to 1·2 cm. in diameter above, sparsely pustulate above; lobes of two different lengths, pustulate; the longer 1·7 cm. long, ovate, acuminate; the shorter 9 mm. long with membranous margins. _Corolla_ 2·5 cm. in diameter when expanded; petals up to 1 cm. long, 1 mm. broad, linear, obtuse. _Filaments_ about 5 mm. long, hairy at the base. _Ovary_ 10-celled; styles 10 free. _Fruit_ not seen. * * * * * PLATE 54.--Fig. 1, calyx and calyx lobes; Fig. 2, petal; Fig. 3, stamen; Fig. 4, top of ovary showing styles; Fig. 5, transverse section of ovary; Fig. 6, longitudinal section of leaf; Fig. 7, transverse section of leaf near the apex; Fig. 8, apex of leaf.

The species is generally found on dry rocky slopes, and the plants assume a subdecumbent position, very rarely growing erect. It is the only South African species of _Aloe_ which bears leaves without prickly teeth. In the dry summer season the leaves lose their bluish-grey colour and become a copper-red, which gives the plants a very characteristic appearance in the veld. A large number of hybrids have been raised by crossing this species with others belonging to the _Saponaria_ group, and a hybrid, described as _Aloe Lynchii_, was obtained between this and _Gasteria verrucosa_. The late Prof. MacOwan states that sun-birds (_Nectarineae_) are the pollinating agents of _Aloe striata_ and some other species of _Aloe_, and if the birds are kept away by covering the inflorescence with wire netting, few or no capsules are produced.
