(PERTH). 
Distribution. Confined to the northern edges of the Blackwood Plateau, between Nannup and 
Busselton. 
Habitat. Grows on sand over laterite under Eucalyptus haematoxylon low woodland or 
E. marginata/E. calophylla low woodland. The species forms dense populations 5-8 years after fire 
in this area. 
Flowering period. June-Decembcr, peaking August-November. Mature fruits are produced 
No vember-February . 
Discussion. Grevillea bronwenae is an attractive horticultural subject, and is frequently grown 
under the name Grevillea brachystylis "Whicher Range Form". 
Etymology. The specific epithet honours Bronwcn Keighery, my wife, for her help both in field 
work in this and many other studies and for her assistance in maintaining our family during my 
numerous absences in the field over the past 15 years. 
Conservation Status 
Although highly restricted, the range of Grevillea bronwenae is entirely in State Forest, much of 
which lies within the proposed Whicher Range National Park. This species does not seem to be 
under any immediate threat. 
Grevillea brachystylis subsp. brachystylis was located at 20 sites on the Swan Coastal Plain. 
However, 17 of these are road verge populations with little protection. Three populations occur in 
actual or proposed nature reserves at Yoongarillup, Ruabon and Fish Road. 
Grevillea brachystylis subsp. australis is currently known from six sites, four of which are on 
road verges. Two (including the type population) are located in Scott National Park. 
Currently all the above taxa are located in reserves. The variety most at risk appears to be 
Grevillea brachystylis subsp. brachystylis for which the reserves and populations are relatively 
small.
