A very characteristic bush of the South Bechuanaland Region, 
forming a clump of coppice 14-3 ft. high, and some yards 
in diameter. Burchell observes, lc., that it is ‘‘ remarkable 
from the circumstance of its trunk or stems running just beneath 
the surface of the earth, and from which arise a multitude of 
shoots or branches 
The name A. hebeclada, DC., being based on Burchell 2267, 
which was distributed by Burchell as his A. stolonifera, was 
from the first an unnecessary synonym. 
A. stolonifera, Burch., also occurs as a shrub 4-6 ft. high, 
with a stout stem, and devoid of ‘ coppice,’ a form so different 
in habit that Burchell himself entered his No. 2397, from Chue 
Spring, and No. 2402-1 (‘‘ a shrub 5 ft.’’) from British Bechuana- 
Jand, in his MSS Catalogue, as A. heteracantha, Burch., though 
these specimens are very different from his type of that species 
(ie. Burchell 1710, from Klaarwater, Griquatown). As there 
oes not a r, from the available material, to be any other 
difference between them, and as the ranges of the two forms 
overlap, it seems not unlikely that the coppice-like growth may
