long-exserted bracteoles in bud, oblongoid flower heads and in its legume having one or both 
margins crenate. 
The new species is described, admittedly on less than the sort of complete data one hopes to 
have at hand when describing new taxa, because it is very distinct and a name is needed for it in the 
account of the Kimberley flora being prepared at PERTH, as well as for the Flora of Australia. 
Note. The type locality data have been augumented beyond those on the label itself, by notes from 
Fitzgerald’s diary/field book of the Kimberley Trigonometric Expedition of 1905. 
Etymology. This species is named for the collector of the only known material, William Vincent 
Fitzgerald, to perpetuate the memory of a keen field observer and one of Western Australia’s most 
respected early taxonomists.
