often springing not far from the ground. The fruits vary in 

 size on the same tree, and can sometimes be found scarcely 

 larger than those of C. robusta. 



Geamineae. 



Eriochloa punctata, (L.)., Hamilt. Frome River near 

 Marree (Hergott). 



Pappophorum avenaceum, Lindl. Common at Marree. 



Eragrostis falcata, Gaud, non Benth. (E. lacunaria, 

 F. v. M.). Berri, Lake Bonney, and other places along the 

 Murray; Everard Range (S. A. White). Plate 25, which 

 accompanies Gaudichaud's description of E. falcata, and which 

 shows the spikelets distinctly pedicellate, rather distant, and 

 not clustered, supports the statement in Diels et Pritzel, 

 Fragm. phyt. Austr. occ. 76, that the original specimen of 

 Gaudichaud's plant, preserved in the Berlin Herbarium, 

 belongs to the species described in the Fl. Aust., vii., 649, 

 as E. lacunaria, F. v. M. 



E. Dielsii, Pilger. (E . falcata, Benth. non Gaud.). Berri 

 and along the Murray; Marree; Oodnadatta ; Mulka (R. 

 CoGkburn) ; Strzelecki Creek (S. A. White); also Broken Hill, 

 N.S.W. Stems stouter than in E . falcata, Gaud., and spike- 

 lets more curved. 



*E. major, Host. Roadside near Berri (C. G. Savage). 

 This European grass has already been recorded in Victoria 

 and New South Wales. It is said that cattle will not eat it on 

 account of the obnoxious smell of the leaves when fresh, and 

 in North America it is known as "Stinking grass." In 1912 

 (these Trans., xxxvi., 172) I recorded the occurrence of *E. 

 minor, Host., at Alice Springs, N.T., and Broken Hill, 

 N.S.W. , so that it probably occurs in our north-eastern 

 country, although I have no specimens from South Australia. 

 These two grasses resemble each other, both having a row of 

 glands or tubercles along the margins of the leaf-blade, but 

 E . minor is a smaller plant, with a looser panicle, narrower 

 spikelets (l|-2 mm. broad), and the leaf -sheath is sprinkled 

 with tubercles, many of which carry long hairs. E. major 

 has glabrous sheaths, and the spikelets are 3 mm. broad. 



RottboelUa compressa, L. f. (Hemarthria compressa, 

 R. Br.). Bridgewater (H. W. Andrew); beside River Onka- 

 paringa, Woodside. The sessile spikelet is 8-9 mm. long, and 

 has only 1 stiff, green outer glume, the 2 inner glumes being 

 hyaline, with a short palea in the uppermost one. The pedi- 

 cellate spikelet is 10 mm. long, has 2 stiff outer glumes, 2 

 hyaline inner ones, and a palea. It therefore appears prob- 

 able that the second outer glume of the sessile spikelet exists, 

 but is adnate to, and obliterated in the rhachis, as described
