(Bt).
Information
Perennials with usually only one stem from a swollen base up to 150 mm long usu­ally little branched towards apex and with almost white circular phyllopodia but later with brown peeling bark. Leaves linear to linear-lanceolate, 15-40(-50) x 2-4 mm, abruptly cuneate, acute, terete to flat or slightly grooved above, usually glabrous or with a few glandular hairs when young, grey-green to greyish brown and often with brown striations. Inflorescence a thyrse with rarely more than 3 monochasia, each with 2-5 flowers, rigid, glandular-pubescent; pe­duncle (40-)60-100(-130) mm long, pale brown; pedicels 5-12 mm long. Calyx 5-6 mm long, glandular-tomentose to pubes­cent, brown rarely yellowish brown; lobes triangular-lanceolate, acute. Corolla glan-dular-tomentose to pubescent, pale brown with darker indistinct venation; tube elon-gate-urceolate, 12-14 mm long, with fine hairs inside, particularly where filaments are fused to tube; lobes 3-4 mm long, recurved towards apex. Anthers 1,1-1,5 mm long. Squamae oblong to oblong-cuneate, 1-1,2 x 0,8-1 mm, usually deeply emarginate, somewhat fleshy, yellow. Fig. 3:3.
Habitat
The habit of the plants and the short phyllopodia of this species are very similar to those of T. reticulatus subsp. phyllopodium (no. 26b). However, T. pearsonii is easily distinguished by its round-topped thyrse of which usually only the straight erect peduncle persists, but also by its longer corolla (15-18 mm) and pendu­lous buds.
Use
13. Tylecodon pearsonii (Schonl.) Tolken in Bothalia 12: 380 (1978). Type: Cape, between Annenous and Chubiesis, Pearson 5981 (GRA, lecto.!).
Range
Found from south-western South West Africa/Na­mibia throughout Namaqualand to the vicinity of Van-rhynsdorp in the north-western Cape Province; locally frequent on gentle slopes or plains, usually on areas covered with quartzite gravel. Flowering period: November, December.
