The usually waxy leaves of different forms of A. umbraticola
65)mm long, 5 to 14 (to 21)mm wide, obtuse or rounded, grey- green or glaucous, often tinged brown and sometimes with faint purplish spots (res- embling some forms of A. schuldtianus). Inflorescence is grey-green, 15 to 25 (to 35)cm long, with single flowered fertile bracts. Corolla is pale green more or less tinged pink and with bloom, lobes off-white to slightly tinged pink or deep mauve in the throat.
Reported from the Highveld region around Pretoria, bet- ween Potchefstroom, Heid-
elberg, Cullinan and sometimes as far west as Zeerust, growing in south- facing rock crevices, or in shallow gravel on rocks, often in shade of other plants.
Type: Transvaal, Silikaatsnek, Smith 3432 (PRE, holotype).
subsp. ramosus Tólken, Bothalia 12:386 (1978) - as subsp. ramosa; FI. Southern Afr. 14:48 (1985), spelling corrected
This subspecies is known even less than the type. Plant material in cultivation is supposedly from the type locality of Chunies Poort in Northern Province. The plant which carries an early UCBG designation (see page 103) is similar to a recent collection by David Cumming. Both are much smaller in all respects than the type, contrasting with Tolken’s description of this subspecies as larger than the type. Recent collections from near Verena have long, plain, pale, unmarked leaves arising from somewhat tall, tuberous stems. These develop a beautiful pink edge to the leaves when given good light, and are close to subsp. ramosus. More field work is needed to determine the standing of this subspecies or the extent
of the species as a whole.
Described as having branches (40 to) 60 to 120mm long, little branch- ing, tuberous at base, Leaves green often tinged brown, rarely grey- green, without spots. Corolla with- out trichomes.
Reported rare between Middel- burg, the Soutpansberg and Blou- berg, usually growing in shallow soil or in rock crevices in large rock outcrops.
Type: Transvaal, Chunies Poort, Tólken 1215 (PRE, holotype).
