Aflinity to 0. hmeophracta, differing in the larger leaves, larger and 
shortly but distinctly pedicellate flowers Avhich are more numerous in the 
cluster, in the vestiture of the calyx which consists of fine silky hairs, and 
the longer and more acute calyx-lobes.

Amicissimo cIarissimo([ue viro, Gulielmo Fdwardo Blackall, scientiae 
medicinae doctori, novum hoc genus dedicoj qui socius humanissimus et collega 
de rebus Australiae occideutalis botanicis maxime eiaiditus, saepe saepius 
])artes huius regionis incultas mecum peragrinavit. 
A genus closely related to (.h’yt)tandra, of which it has many of the 
characteristics, but the completely superioi' ovary and the small annular 
free-margined disc are characters of the Tribe Colletieae, of which Blackallia 
is typical except that the branchlets and leaves are alternate and not opposite. 
It is close to Disearia, differing in the erect + connate calyx-lobes, the 
capsular fruit, as well as in the arrangement of the branchlets and leaves. 
The calyx does not appear to spread its lobes, which in all the specimens 
examined are + connate and erect.
