(Myrtaceae), a new species from the North Western Slopes of New South Wales Telopea 9(2): 431-433. 
Homoranthus binghiensis J.T. Hunter, a new species from the Torrington region of the North 
Western Slopes of New South Wales is described and notes are provided on its distribution and 
conservation status. The species is distinguished from its putative sister taxa by particularly thick 
leaves and a combination of ovule and sepal laciniae number. 
Introduction 
During a vegetation survey of the Torrington State Recreation Area (Clarke et al. 1998) 
an unusual and very distinctive Homoranthus was discovered. The specimens collected 
of this entity were shown to represent a geographically restricted unnamed species, 
which seems not to have been previously collected. This species is described in this 
paper and notes are given on its distribution, conservation status and putative affinities.
