Plates XLVII. and XLVIII. 



The district placed in brackets after the name of a locality 

 aneans that the record is a new one for that plant in one oi 

 .more of the botanical districts defined in Tate's "Flora of 

 J^xtra-tropical South Australia." Some interesting new 

 records were made by Mr. Rodney Cockburn, Secretary of 

 the Railways Standing Committee, while travelling in the 

 Par North-east in June last. 



Gramineae. — Eragrostis leptocarpa, Bentli. Between 

 Goyder Lagoon and the Queensland border (R. Cockburn). 

 This handsome grass, whose panicles become purple with age, 

 has the flowering glume obtuse when spread open (not "rather 

 acute," as described by Bentham) and the palea almost 

 glabrous, with the nerves produced upwards into two acute 

 lateral lobes. 



Chenopodiaceae. — I have found it impossible to deter- 

 mine satisfactorily the number of spines in Bassia paradoxa 

 (R. Br.), F. v. M., either in the flower or fruit under ordinary 

 conditions. However, by macerating one of the fruiting heads 

 in lime-water all the wool was removed, and it then appeared 

 that the head consisted of eight connate fruits, of which one 

 was 2-spined, one was 3-spined, two were 4-spined, and four 

 were 5-spined. It is clear, therefore, that this species will 

 not fit into the genus Scleral aena (2 dorsal spines), in which 

 it was placed by Brown and retained by Bentham, or into 

 Anisacantha (3-5 dorsal spines). 



Amarantaceae. — Alternanthera an gusti folia, R. Br. 

 Between Goyder Lagoon and Queensland border (R. Cock- 

 burn) ; Oodnadatta (Miss Staer). A new record for the State. 



Crtjciferae. — Alyssum lini foil urn, Steph. Government 

 Farm, Minnipa (Dist. L or W). Capsella pilosula, F. v. M. 

 -Government Farm, Minnipa (Dist. L or W). 



Leguminosae. — Psoralea eriantha, Benth. Oodnadatta 

 (Miss Staer) ; between Goyder Lagoon aifd Queensland border 

 (R. Cockburn; Dist. C). Grotalaria Cunninghamii, R. Br. 

 uVIulka (R. Cockburn). This plant, with its showy golden and
