Aloe humilis, Haw. (A. perfoliata humilis, Linn.). Lvs. suberect, rather incurved, triangular-lanceolate, ¾ x 4 in., gradually acute, somewhat striate, sharply white- tuberculate, at least on the back, and with rather close large white marginal teeth: infl. 1½-2 ft. high: fls. 1½ in. long, red or yellowish, the green-tipped segm. distinct nearly to the base. Cape. Sahn, Aloe §15, f. 1.—With somewhat the habit of Haworthia. Varies from the narrow green-lvd. type into glaucous forms of this, with rather thicker lvs., var. incurva, Haw. (A. incurva, Haw.), B.M. 828, Salm, Aloe §15, f. 3, and rather thin, more concave lvs., var. echinäta, Baker (A. echinata, Willd.), Salm. Aloe §15, f. 2., Berger 64, 65, and one with purplish lvs., var. macilenta, Baker; as well as a broader-lvd. glaucous large form, var. suberecta, Baker (A. suberecta, Haw. A. acuminata major, Salm-Dyck), which is sometimes white-mottled, var. semiguttata, Haw.; a moderately large broad-lvd. form, var. acuminate, Baker (A. acuminata, Haw., A. suberecta. Haw.), B.M. 757; and a small blue- glaucous form with closer prickles and smaller warts, var. subtuberculata, Baker (A. subtuberculata, Haw.). Hybrids are: A. x insignis, Brown (A. humilis x A. drepanophylla), A. x spinosissima, Hort. (A. humilis echinata X A. arborescens pachythyrsa), A. x cyanea, Hort. (A. humilis incurva x A. arborescens frutescens), A. x Todari, Borzi, (A. Todari praecox, Borzi,) A. x Grusonii, Henze, Monatschr. Kakteenk. 11, p. 57. (A. humilis x A. Schimperi), A. x Henzei, Hort. (A. Grusonii x A. variegata), and perhaps A. x laetecoccinea.
