n which genus it is one of a group of probably four closely allied but 
bide distinct species aggregated by Bentham in the Flora Australiensis, 
vol. iv. p. 399, under H. tenuifolium, r. e contrast emphasised 
in the differential diagnosis is with specimens from the Gulf of Carpen- 
taria collected by Brown which form the basis of his species. If the 
printed label which accompanies the specimen delineated (Mr. Gosse’s 
xpedition. Interior of South Australia. Comm. R. Schomburgk, 
May 1874) could be taken literally, mh locality in which H. Gossei was 
collected ought to lie somewhere between the Mann and the Musgrave 
Ranges or within the latter range. But Gosse’s expedition also covered 
considerable ground in the south-western corner of the Northern 
erritory (from Reynold Range to Mann Range) and extended for 
a short distance into West te so that the precise tonality of 
the species is doubtful—O. Sra
