STACKHOUSIA FLAVA, Hook., var. Donkey rocks, June. This 
variety has pubescent bracts and floral axes. The petals also are 
sumewhat blunter than are those of type specimens. Might 
possibly be regarded as a new species. 
Another Stackhousia, probably typical A. flava, Hook., is 
rather abundant on the Nine-mile rocks near Coolgardie, but, as 
no specimens are to hand, I must somehow have omitted to 
press any. 
The Stackhousie, so far as my observation goes, grow only on 
decomposed granitic soil. 
RHAMNACE E. 
PoMADERRIS FORRESTIANA, F. Muell. A shrub about 3 feet 
or so, with white flowers, near Gnarlbine, September. A lowly 
shrub, up to 2 feet, with brown flowers, between Coolgardie 
and Gnarlbine, October. I can see no essential difference 
between the two.

A plant with the habit of T. Wichure, Nees, to which it is 
doubtless closely allied. The leaves, however, are somewhat 
different in shape, and the cymes longer than the leaves and with
