 perceive no indication of such 'a palate. In the above-mentioned 

 specimens, the calycme segments are smooth within ; the corolla 

 IS also smooth, and hairy only in the mouth and upon the lobes 

 of the border. Galeotti's specimen, as I have before observed, 

 has distinctly five fertile stamens, Hartweg's has only four.

In this species the branchlets are more glabrous, more tortuous 

 and more knotty at the axils of the fallen leaves, often spinous 

 at the short abortive branchlets, the leaves more obovate-oblone 

 and rounded at the apex, the younger leaves incanous, not fer- 

 rugmous, the calycine segments more oblong and broader : the 

 leaves are 7 or 8 lines long, 4 or 5 lines broad, the petiole being 



calyx 



including the lobes of the border, is 1 inch long : the calyx 

 though persistent, does not mcrease in size in fruit ; the capsule 

 IS small, ovate 1| line long, the two valves being inflected at the 

 margin, very thick and coriaceous, and bifid nearly to the base.
