Carex tereticaulis, F. v. M. Ferguson Gorge, near 

 Moolooloo (E. H. Ising). Approaching C. chlorantha, R. Br., 

 in its short panicle (5 cm. long), spike-like but interrupted 

 towards the base, and tending towards C. appressa, R. Br., 

 in its subtrigonous stems and leaves scabrous on the margin 

 in the narrow upper portion. 



Centrolepidaceae. 



Centrolepis polygyria, Hieron. Soak at Winnike Berick, 

 south of Lameroo. 



JUNCACEAE. 



Juncus holoschoenus, R. Br. Monbulla scrub (H. W. 

 Andrew); Dismal Swamp, S.E. ; Waterfall Gully; Myponga. 

 Our specimens agree with Brown's characters — stem cylindrical 

 or nearly so ; stamens 6 ; capsule equalling the perianth ; also 

 with Buchenau's character of the complete septa in the leaves. 

 The plants from Monbulla and Dismal Swamp are dwarf. 

 It appears doubtful whether we possess /. pr is mat o car pus, 

 R. Br., in South Australia. All the specimens so named in 

 the Tate Herbarium (from Waterfall Gully, Reedbeds, 

 Mannum, Wirrabara, and Wilpena) are /. holoschoenus. 



J. pallidus, R. Br. Banks of Torrens Lake; Waterfall 

 Gully; Slape Gully; Myponga; Nuriootpa ; Woodside; Mount 

 Gambier; Glencoe; Dismal Swamp. This species, as correctly 

 denned, has always 6 stamens; capsule 3-4 mm. long, pale 

 coloured and usually exceeding the perianth considerably; 

 stems stout, with continuous pith. 



LlLIACEAE. 



Thysantftus Patersonii, R. Br. Pinnaroo (Dist. M). 



Casuarinaceae. 



Casuarina Luehmannii, R. T. Baker. "Bull Oak." Few 

 miles south of Lameroo. Tree 8-10 m. high, with rough, 

 brown bark ; lowest branches drooping, uppermost spreading- 

 erect; trunk usually without branches for 2 m. above the 

 ground; internodes to 20 mm. long; young cones tomentose. 



C : lepidophloia , F. v. M. Oodnadatta (Dist. C) ; W. A. 

 Cannon); sheathing teeth 9-11. Willigin Water, near 

 Moolooloo (E. H. Ising); teeth 11-12. C. lepidophloia was 

 described by F. v. Mueller in 1877 ; Bentham, in dealing with 

 this genus in 1873 (Fl. Aust., vi., 196), placed specimens of 

 C. lepidophloia under C. glauca, Sieb. Mueller distinguishes 

 the former species as having 9-10 sheathing teeth; C. glauca, 

 as now understood, "having usually 15 in the whorl, varying 

 from 12-16" (J. H. Maiden, For. Fl. N.S. Wales, ii., 95). 

 Mr. Maiden is of opinion that C. glauca has not yet been
