England Tableland of Neiv South Wales. Telopea 9(2): 323-327. Dillwynia rupestris Jobson and 
P.H. Weston, a new species from the New England Tableland of New South Wales is described 
along with its ecology, distribution and conservation status. Dillwynia rupestris closely resembles 
D. acicularis, but differs in having broader, mostly shorter leaves, mucros being paler and less 
conspicuous; and inflorescences having more flowers and being tightly arranged in structure. 
Introduction 
The 'granite country' of the New England Tableland runs for approximately 400 
kilometres in length from Stanthorpe in southern Queensland to near Tamworth in 
central New South Wales. The communities associated with these outcrops are both 
diverse and significant in the number of rare and restricted taxa present (Hunter & 
Clarke 1998). This new species is endemic to this 'granite country'. 
Dillwynia rupestris Jobson & P.H. Weston is a member of the section Xeropetalum. This 
species has been recognised informally for the last thirty years, and for the Flora of New 
South Wales treatment (Weston 1990) was called Dillwynia species A. Strangely, Beadle 
(1976) did not include it in his treatment for his Student's Flora of North Eastern New 
South Wales, although collections made in the 1960s by J.B. Williams, are housed at the 
N.C.W. Beadle Herbarium (NE). One of us (PCJ) has examined this species in the field 
and was able to make observations of its habit and habitat. We name this new species 
below, provide information on its distribution and ecology, and assess its conservation 
status. We also compare it with species that appear to be its closest relatives.
