Michelii. [Found near dry watercourses on the tablelands: 

 introduced by sheep most likely.] 



Aristida stipoides, R. Br. Between Innamincka and 

 Kanowana. [Growing amongst gibber stones.] 



Stipa scabra, Lindl. Six miles north-east of Farina. 

 [Found growing in most stony localities.] 



Glyceria ramigera, F. v. M. Cuttapirie Corner, Cooper 

 Creek. To the descriptions of this curious grass given by 

 Mueller and Bentham should be added : — Palea glabrous on 

 nerves, readily splitting into two halves ; lodicules distinct : 

 grain oblong, loosely enclosed in the membranous pericarp. 



Sporobolus actinocladus, F. v. M. Mount Hopeless. The 

 leaves of all my specimens of this species, and also of those 

 in the Tate Herbarium, are shortly scabrous-ciliate. 



Triodia pungens, R. Br. "Porcupine grass." Lake Peri- 

 gundi. Spikelets rather larger than in Bentham's description 

 — 10-12 mm. long, and the flowering glume 6-7 mm. long. 

 This species was found by Helms on the Arkaringa Creek in 

 1891, and has therefore been already recorded for South 

 Australia. [Met with this plant at Lake Perigundi for the 

 first time; not in any quantity.] 



Panicum leucophaeum, H. B. et K. Innamincka. [This 

 grass was growing amongst the stones on tablelands.] 



Plagiosetum refract um, Benth. Fifteen miles west of 

 Innamincka. To the descriptions of Mueller and Bentham 

 should be added that the flattened panicle branches (or 

 peduncles of the involucres) sometimes bear 3 and even 4 

 spikelets. Where there are 4, the 2 central ones are arranged 

 on the central pedicel (or branch of the involucre), one near 

 its thickened base and the other at its summit, while the 2 

 others stand somewhat higher on lateral pedicels, and have 

 also bunches of the long involucral bristles behind them. 

 [This grass was met with in the sandhill country to the south 

 of the Cooper ; stock eat it ; only seen once or twice.] 



Eriochloa punctata (L.), Hamilt. The typical form, 

 with spikelets 3-4 mm. long and pedicels and rhachis of spikes 

 minutely pubescent, was collected between Innamincka and 

 Kanowana. Then there is another form from Munge'ranie, 

 with similar pubescence on pedicels and rhachis, but the 

 pedicels have also a few long hairs at the summit, and the 

 spikelets are 9-10 mm. long. I have exactly similar spikelets 

 from Oodnadatta. These specimens, with the outer glumes 

 three times as long as the type, would appear to constitute a 

 very marked variety, were it not that intermediate forms, 

 with the spikelets 5-8 mm. long, are to hand from Mount 

 Gunson (Mrs. Beckwith) and from Torrens Plain and Gidia 

 Creek (Tate Herbarium). These may, perhaps, represent E.
