Names
Aloe thompsoniae [family ALOACEAE]
Information
Much-branched grass aloe 150-200 mm tall, suckering to form dense recumbent to pendent clumps; roots fusiform. Leaves 12-18 in a rosette, lorate, 90-200 x 4-15 mm, often reflexed, canaliculate, apple-green, margins dentate. Inflorescences 1-3 from a rosette, sim­ple, with subcapitate to conical racemes; pedun­cle 150-200 mm long, with sterile bracts; bracts deltoid-acute, 9-10 x 3-6 mm, 5-8-nerved. Flowers orange, 22-28 mm long; all segments free; pedicels 9-24 mm long. Anthers not exserted. Ovary 4.0-5.0 x 1.5-2.0 mm, lemon-yellow; style not exserted. Flowering time December to January.
Habitat
In this species and A. nubigena (no. 13), both of which are often pendent on rocks, the pedun­cle is bent, often in a U-curve, so that the raceme is always vertical. A. thompsoniae dif­fers from A. nubigena by being a smaller plant with stiffer leaves and bracts with distinct veins. In A. thompsoniae the leaves are rosulate, but in A. nubigena they are often distichous. This species has rosulate leaves and bracts with dis­tinct veins, and grows in clumps, whereas A. soutpansbergensis (no. 12) has fewer leaves, which are distichous when young, and bracts with obscure veins, and is often solitary.
