at the base and incurved upwards so as to each form a 

 deep sinus and present a hooked or anchor-like appearance. 

 In its foliage the new species bears a close resemblance to 

 C. pterosperma. The inset figures (4, 5, 6) show that in their 

 fruits these three last-named species stand much nearer to 

 one another than to C. ancyrocarpa. Bentham states that 

 C. porphyroglossa has a pappus of numerous barbed awns 

 but in my specimens from Alberga Creek I have only been 

 able to find 4-7 awns. For C. pterosperma Bentham gives 

 "8 to 10 very short awns"; in Robt. Brown's type (kindly 

 lent me by Mr. J. R. Tovey, officer in charge of the Victorian 

 National Herbarium), I found 4-6 awns \ mm. or less in 

 length. 



C. multicaulis, (Turcz.) J. M. Black. Tarcoola (Dist. 

 W; J. M. B.). Leaves rather broader, shorter, and less 

 toothed than in the far-northern specimens, but the achenes 

 are the same and the ray is white. 



G. erinacea, Steetz. Bentham (Fl. Aust. iii., 502) says: 

 "achenes with 3-5 awns." In very dry country such as our 

 North- West o<r Far North (Port Augusta, Nilpena, Ooldea, 

 Everard Range, and Finke River, N.T.), or even as far south 

 as Ardrossan, the number of awns is usually only 2, but the 

 achene is easily distinguished from that of G. cymbacantha, 

 because in the latter species the 2 awns are separate, strongly 

 barbed, and placed at right angles to the compressed tuber- 

 culate faces of the achene, while in C '. erinacea the 2 awns 

 are united in a cup at the base, are very slightly barbed, and 

 placed parallel to the compressed faces of the smooth achene. 

 In a Renmark specimen I have found some achenes with as 

 many as 8 awns, 2 of the normal broad awns being each 

 replaced by 3 smaller awns. Specimens in the Tate Herbarium 

 from Ideyaka have 8 or even 9 awns. The type (from Swan 

 River) had 4 awns: "aristis 4 subaequalibus achaenium 

 laevissimum aequantibus obverse aculeatis" (Steetz in PI. 

 Preiss. i., 424). Similar specimens with 4 or sometimes 3 awns 

 united in a cup at the base are from Renmark, Lake Peri- 

 gundi, and in the Tate Herbarium from the MacDonnell 

 Range, N.T., and the Barrow Range, W.A. 



Leptorrhynchus tetrachaetus, (Schlecht.) combin. nov. 

 (L. pulchellus, F. v. M., in Linn, xxv., 500, ann. 1852; 

 Doratolepis tetrachaeta, Schlecht., in Linn, xx., 593, ann. 

 1847). Nov. var. penicillatus. Variat pappi setis 1-3 superne 

 plumoso-penicillatis, pedunculi squamis inferne herbaceis in 

 folia caulina transientibus. 



Marree, Leigh Creek, Tarcoola (J. M. B.); Strzelecki 

 Creek (Tate Herb.). This appears to be a dry-country form 

 of the species. The pappus resembles closely that of Athrixia
