THE TLOEA OF THE NOBTHBRN TERBITOBY. 267 



1 . L. agrostophylla, F. v. M. — Sandstone tableland of the Upper Victoria 

 River and MacArthur River, GuK of Carpentaria, F. v. Mueller. 



2. L. divaricata, F. v. if .— Macdonnell Ranges, G. F. HiU (168), 12/5/1911. 



3. L. filiformis, R. Br. — Sandstone Ranges, Borroloola, G. F. HiU (595), 

 2/10/1911. 



The Borroloola specimens are exactly like those collected by R. Brown at 

 Carpentaria, as represented in the Melb. Herbarium, having short weak decum- 

 bent stems about 6 in. high. The flowers are 18 mm. long, intermediate between 

 L. filiformis and L. agrostophylla ; but, as in the latter, a narrow wing is seen 

 on both sides of the two upper lobes of the coroUa, and the two lips of the 

 indusium are densely cihated, as figured by MueUer, in contrast with their 

 usually glabrous condition in L. filiformis. Capsule unformed. 



The leaf and general appearance more closely resemble L. filiformis. The 

 difficulty could be settled by making L. agrostophylla a variety of L. filiformis. 



Recorded. Islands of the GuK of Carpentaria, R. Brown.
