Affinity with S. Dunnii Hook. f. and S. Cooper i Clarke, from which 

 it is easily told by the corollas.

Affinity with J. heterocarpa T. And. and J. leptocarpa Lindau, 

 differing from both in the broader segments of the calyx which do 

 not run out into very long fine points. Mention should also be made 

 of the larger and broader normal capsules of J. Dinteri, and its 

 decidedly different abnormal ones with their broader wings, either 

 simply undulate or provided with a very fcAv broad lobules, instead of 

 many small teeth. 



Study in the living plant of the capsular dimorphism of this and 

 its fellow-species of § Rarniera should 3'ield results of interest.
