1. R. Zeyheri.—Scaberula ; caule (subsimplici? ut videtur) 
erecto, subtereti, striato-angulato ; foliis sessilibus, lanceo-

formi, longissimo, lateralibus brevibus, dentiformibus, incur-

Of this I received a single and not very perfect specimen 
in 1838, from Mr. Zeyher, who gathered it “in a field by 
the Zwart Kops River," and who informs me that it had a 
tuberous root, like that of Brachystelma. The specimen, 
which is evidently young, is about five inches high, and appa- 
rently erect. Flowers greenish

ramis divaricatis, compressis, ancipitibus ; foliis petiolatis,

lato-cuspidatis, cuspide brevi. (v. s.) 
Of this also I possess only a solitary specimen, which was 
gathered at Port Natal by Miss Owen, and communicated to 
me by H. B. Rutherford, Esq. It is seemingly decumbent, 
and much branched in a di-trichotomous manner. Flowers 
purple.
