This species, the two very closely allied which follow, and B. capitata, Klotasch 
(from Mozambique), form a striking group, recognized by the trailing stems with 
smnall leaves and large thick densely strobilate heads of fruit. Nees supposed 
“Burke” to be an abbreviation for ‘‘ Burchell”; his two species, B. macro- 
stegia and B, burchelliana, are founded on one collection. Sonder attempted to 
correct the specific name. ‘The difficulty is evaded by taking up macrostegia,

densely grey-silky-strigose ; leaves up to 1} by 2 in.; posticous sepal 
with a long spinous mucro and spinescent teeth } in. long on the 
margins; otherwise as B. macrostegia. Masters in Gard, Chron,

Kloof Village, Burchell, 1652! on plains at the foot of the Asbestos Mountains, 
between the Kloof Village and Witte Water, Burchell, 2068! 
T. Anderson, either by accident or from supposing it not specifically distinct 
from B. macrostegia, omits this plant altogether. The flower in Burchell, 2068, 
is normal; arrested flowers, as those figured by Masters, also occur ; such occur 
in other species of the genus, and in other genera of the Order, and may be (fide 
Masters) connected with self-tertilization. 
17. B. media (C. B. Clarke) ; softly and somewhat thickly hairy ; 
innovations densely grey-strigose ; leaves 1 by 3 in.; posticous sepal 
with a long spine at the tip, softly ciliate, hardly toothed on the 
margins; otherwise as B. lichtensteiniana. 
Katanarr Region: Bechuanaland; on the rocks at Chue Vley, Burchell,

The young shoots are grey-strigose, often with deflexed hairs, exactly as in 
Bi Waktencteindden. The spine-tip of the posticous sepal is as of B. lishten- 
steiniana, but the margins without teeth are as of B. macrostegia. I think 
the South African plants of this group must be arranged either as three species 
orasone, ~
