subject to flooding.] G. eriocarpa, Benth. Mount Hopeless; 

 Ambuginia Creek. In addition to the particulars given in 

 these Trans., xl., 461, it should be remarked that the com- 

 pound heads attaiu a diameter of 10 mm., and consist of 

 numerous primary partial heads or involucres consisting of a 

 few woolly bracts without laminae, and each containing about 

 5 secondary 1 -flowered partial heads. The involucre of these 

 1 -flowered heads consists of 5-6 oblanceolate scarious concave 

 bracts united by their wool, with green midribs and small 

 almost colorless tips, and of 1 still narrower subtending bract. 

 [Great quantities of this plant were found growing upon 

 flooded ground. During the latter part of our travels, in 

 October, it had dried off, and was invariably used by many 

 species of birds in nest-building.] 



Gnephosis skirrophora, Benth. Mount Lyndhurst. This 

 species has a wide range in South Australia, extending from 

 Mannum, on the River Murray, to Dalhousie Springs, beyond 

 Oodnadatta, and westward through the Gawler Ranges to 

 Minnipa and Murat Bay. While exploring in the neighbourhood 

 of Lake Eyre in 1872, Ernest Giles collected a plant which was 

 described by Mueller in his Fragmenta, ix., 2 (February. 

 1875), as Angianthus codonopappus — "Gnephosis codono- 

 pappus (sic) t F. M. coll.," being given as a synonym. In 

 the 1st Census (1882) the name appears as "G. codonopappa, 

 F. v. M., in Giles, geog. trav., 217 (1875)." This plant has 

 'only been described twice — once from the specimen which 

 reached Mueller, and once, very shortly, by Tate (Fl. 

 Extratrop. S.A., 128). G. skirrophora has been described 

 "by Sonder and Mueller (Linn., xxv., 490) : Bentham (Fl. 

 Aust., iii., 570); Tate (I.e.); Moore (Fl. N.S.W.. 288), and 

 Mueller (Key Vict. PI., 334). If these descriptions are com- 

 pared, the characters appear as follows: —
