Ne distinctive characters are mentioned by DeCandolle in his 
diagnosis of the above two species that are not shown by the 
large series of specimens at hand to be of no value, and their union 
Seems necessary. Although the name HE. mucronatus (mucrona- 
tum) has been most used by botanists, it seems desirable to adopt

tion, which in this case is H. Karvinskianus. The error through 
which Sonder was led to adopt for this plant, then cultivated in- 
European gardens, a name based on the Australian Brachycome
