but narrower and paler; the leaves are much larger and more 

 crowded ; it differs moreovefj essentially, in the structure of the 

 flowers. The leaves are comparatively thin in texture, veinless, 

 nearly an inch long, including the slender petiole, and 1^ to 2 

 lines broad; the peduncles are 6 lines long; the tubular calyx 

 2 lines, the tube of the corolla 8 or 9 lines, the segments are 

 1 to 1| line long*.

This is well distinguished by the rather dense pubescence 

 which clothes the stemlets, the spines and the leaves. In Drege's 

 specimen the leaves are elliptic, oblong, acute, attenuated at the 

 base into a slender petiole of one-third the length of the blade ; 

 the total length being 9 to 12 lines, and their breadth 3 or 4 lines. 

 The specimen from Graham's Town is much more branched, the 

 branchlets and spines arc nearly at right angles and densely 

 beset with clusters of leaves ; here the petiole is nearly obsolete, 

 the leaves are only 3 or 4 lines long and 1^ or 2 lines broad : 

 the flowers, upon an extremely short peduncle, are nearly sessile : 

 the tubular and very pubescent calyx is larger than in the other 

 specimen, its tube being 2 lines, and its nearly equal hnear teeth 

 being widely spread and 1 or 1^ line long: the tube of the 

 corolla is 4 lines long, nearly cylindrical, with a border of five 

 rounded oblong segments, ciliated on the margins, nearly a line 

 in length : the stamens are nearly equal in length, inserted con- 

 siderably below the middle of the tube, hirsute for about one- 

 fourth their length, and reach the mouth : the flowers in this 

 specimen are in a bad condition f*
