It is very difficult to resist the suspicion that Mueller, in 

 describing G. codonopappa as an Angianthus, had for the 

 moment forgotten the existence of G. skirropkora. The pro- 

 bability is strengthened by the fact that he does not compare 

 his new species at all with G. skirrophora, but merely says 

 that "it will stand in the vicinity of G. cyathopappa," a 

 species which is well distinguished by having two flowers to each 

 partial head. It may be mentioned that the receptacle of 

 G. skirrophora is both "convex" and "depressed," that is 

 to say, it is cushion- or buffer-shaped, and almost flat on the 

 broad summit. Tate's description is evidently a mere abridge- 

 ment of Mueller's, for the Tate Herbarium contains no speci- 

 men named G. codonopappa. The question was submitted to 

 Professor Ewart, who very kindly examined the specimens in 

 the National Herbarium of Victoria, and came to the con- 

 clusion that G. codonopappct is a separate species, distinguished 

 from G. skirrophora by having the pappus-cup less lobed, the 

 bracts of the partial involucre more acute, the receptacle less 

 hairy and more flattened, the bracts as long as or longer than 

 the flowers, and the leaves more crowded. So variable is the 

 pappus of G. skirrophora in length and degree of lobing that 

 I can attach no importance to that distinction, but in the 

 type-specimen which Prof. Ewart kindly lent me, the leaves 

 were much crowded, the receptacle had shorter hairs, and the 

 bracts were more acute and a trifle longer than is usual in 

 G. skirrophora. It was a small plant, 7 cm. high, with short 

 stem and 3 branches, and as the flowers were only in bud 

 I could not judge of their length in comparison with that 

 of the bracts. But as regards the short-haired receptacle and 

 more acute bracts it agreed with specimens in my herbarium 

 from Dalhousie Springs and Mount Lyndhurst. These, how- 

 ever, have the limb of the corolla exserted from the bracts,, 

 just as in G . skirrophora. The type specimens of G. codono- 

 pappa seem to be dwarfed by the barren and arid character 

 of the country near Lake Eyre, and at most to be scarcely 

 more than a variety of G. skirrophora. Further material 

 would be very welcome to throw more light on the question. 

 It may be added that Angianthns codonopappus is recorded 

 by Mueller in Journ. Bot., xv., 303 (1877), as having been 

 found by Giles on his journey westward in 1875 "between 

 boundary line and Victoria Springs." This locality is in 

 Western Australia, but in both the 1st and 2nd Census G. 

 codonopappa is only recorded for South Australia.
