Strzelecki Creek, south-west of Innamincka ; Cooper 

 Creek, at C'uttapirie Corner. There is also a specimen in the 

 Tate Herbarium from Cootenoorina Creek (west of Oodna- 

 iatta), and placed under P. effusum. Nearest to P. bicolor, 

 R. Br., from which it differs in the broader leaves, the hairy 

 rhachis of the panicle, the lowest glume only one-third as long 

 as the spikelet, and probably also in the distinct nervation of 

 the fruiting glume. P. bicolor belongs to the coastal regions 

 of Eastern Australia, while the new species, named in honour 

 of the collector, is a desert grass. [Seen in many localities 

 growing on ground lately flooded by heavy rains ; forms good- 

 sized clumps and stools out all round ; stock seem to relish it ; 

 also forms a food for seed-eating birds.] 



Astrebla pectinata, F. v. M. "Mitchell Grass/' East 

 of Mungeranie ; Mount Hopeless. [This grass was mostly 

 found growing on the tableland country.] 



Chloris acicularis, Lindl. East of Mungeranie, Innamincka. 

 Spikelets larger than usual; second outer glume 7-10 mm. long ; 

 dowering glume 7-9 mm. long : leaves flat, scabrous down- 

 wards with minute, rigid hairs, visible under the lens; ligule 

 very short, ciliate. [Often found growing round the crab- 

 holes on tableland country, and attaining a height of 2 feet 

 at times.] 



Pollinia fidva, Benth. Mirra Mitt a Creek; east of 

 Mungeranie. 



Triraphis mollis, R. Br., var. humilis, Benth. Inna- 

 mincka; Mungeranie; Carraweena. I have also this variety 

 from Mount Gunson (Mrs. Beckwith). [This handsome-headed 

 grass was found on flooded ground.] 



Pappophorum avenaceum, Lindl. Innamincka; Strze- 

 lecki Creek, south-west of Innamincka. TMet with in many 

 localities ; seems to be of a dwarf nature.] 



Diplachne loliiformis, F. v. M. Between Innamincka 

 and Kanowana ; Mount Hopeless. Dwarf specimens 6-10 cm. 

 high. 



Bromus arenarius, Labill. Mount Lyndhurst. 



*Trisetum pumilum, Kunth. At Mount Lyndhurst this 

 is a dwarf grass only 3 cm. high ; at Woolshed Flat and 

 Hawker it grows with erect stems to a height of about 20 cm., 

 and then much resembles another alien grass, Koeleria
