Notes
The typical subspecies differs from subsp. sonderi in having eglandular stems and ± glandular-fimbriate sepals; it is confined to Cape Province. The Rhodesian and Mozambique specimens, which are smaller and tend to be more branched than most of the S. African specimens, appear to belong to two distinct populations. Those from Chipinga, Melsetter and Mozambique have ovate to oblong, sessile leaves, sometimes longer than the internodes, while the specimens from the Umtali and Inyanga districts have smaller, elliptic or rotund leaves, which may be shortly petiolate and are usually much shorter than the internodes. The distinctness is rather blurred by the Mozambique specimens which, although nearer the Melsetter type than the other, nevertheless show some intermediate characters. The variation may be clinal, and the two populations may only appear to be distinct owing to lack of material from intermediate regions.
