^n the anterior side where it sits on the branch; spines 4-5, 

 the longest two often 25 mm. long. [A common bush on 

 the stony tablelands; much relished by camels.] B. parn- 

 doxa, F. V. M. Everard and Musgrave Ranges. [Plentiful; 

 the sharp-spined fruits gave much trouble to man and beast.] 

 Salsola Kali, L., var. strohilifera, Benth. Twenty miles west 

 of Oodnadatta; Moorilyanna Native Well. [Found through- 

 out the country; much relished by camels.] Enchylaenn 

 tomenfosa, R. Br. Wantapella Swamp. [Growing on ground 

 subject to floods.] 



Amarantaceae. — Amarantus Mitchellii, Benth. Indul- 

 kana Springs. Alternanthera triandra, Lam. Moorilyanna 

 Native Well. [Found growing amongst the granite rocks.] 

 Trichinium incanum, R. Br. Mount Illbillie. I do not see 

 how it is possible, at least in dealing with South Australian 

 and Central Australian specimens, to keep T. incaniim, R. Br., 

 and T. ohovatuin, Gaud., separate, and Brown's name is, of 

 course, the prior on©. The distinctions laid down by Bentham 

 (Fl. Aust., v., 218 and 221) do not hold good in the speci- 

 mens I have seen. The bracts are never really glabrous, but 

 are always woolly at base and beset with very short glandular 

 hairs in the upper part or they are woolly all over. Where 

 they are most glabrous in appearance the flower-spikes are 

 often cylindrical and 25 mm. long, while on globular spikes 

 the bracts may be densely woolly. The hairs (except the 

 minute glandular ones) are stellately branched ; that is to say, 

 the barbs are arranged in several whorls around the axis of 

 the hair, and are much shorter on the hairs of the bracts 

 and bracteoles than on those of the leaves and branches. The 

 hairs themselves vary much in length. Bentham makes 

 ''bracts glabrous or nearly so" one of the leading characters 

 of T. ohovafum, but Gaudichaud himself says "bract eis 

 pilosiuscidis," and his figure shows them pubescent. Var. 

 f/randiflorum, Benth. Five miles west of Todmorden Sta- 

 tion; Glen Ferdinand. Perianth 12-15 mm. long; bracts 

 and bracteoles straw-coloured, glandular-hairy in the upper 

 part. [Met with on tablelands and also in the sandy valleys 

 of the ranges.] T. alopecuroideum, Lindl. Between Mooril- 

 yanna Native Well and Everard Range. T. exaltatum, Nees. 

 Vaughan Hill, 70 miles west of Todmorden Station; Wan- 

 tapella Swamp. [This plant was not nearly so plentiful as we 

 found it north of Oodnadatta the previous year (1913).] T. 

 helipteroides, F. v. M. Everard Range; Musgrave Ranges; 

 Vaughan Hill. [Quite a quantity of these bright little 

 flowers were seen in the valleys of both ranges ; not nearly so 

 plentiful on the tablelands.] T. cor y mho mm, Gaud. East 

 of Everard Range. [It was only in the vicinity of the Everard
