dorsal appendages even in specimens which are otherwise 

 typical. The new variety can be at once distinguished by its 

 very broad thick and soft leaves. My specimens are too few 

 to ensure certainty as to the appendages being constantly of 

 the form described. 



In dealing with the JJassias, I have had the advantage 

 of consultation with Mr. J. H. Maiden, Government Botanist, 

 and Mr. R. H. Anderson, botanical assistant at the Na;tional 

 Herbarium, Sydney. Mr. Anderson is engaged on a much- 

 needed revision of the Australian Ba^sias.

Arkaringa and Alberga Creeks. This species is only 

 known by two specimens collected by R. Helms on the Elder 

 Expedition in 1891, and one obtained by Miss Staer in 1913 

 at Todmorden Station, on the Alberga. Like K. hrevifolia 

 it has five distinct equal horizontal wings Avithout appendages, 

 but differs entirely in the thickness and rigidity of the wings 

 and in their dense woolly clothing. The perianth bears some 

 resemblance to that of K. lanosa or of Bassia ^clcrolaenoides.
