198 J. H. MAIDEN. 



Synonym. — A. ulieina Meissn. var. oxyclada Mueller and' 

 Tate, Herb. 



A. Basedoivii is identical with a specimen sent to me by 

 Tate from the Adelaide Herbarium labelled "A. ulieina var. 

 oxyclada, McDonnell Range. W. H. Tietkens, July 6, 1889. " 

 There is no record of this plant in Tietkens' Diary in his 

 Journal of the Expedition, nor in the catalogue (furnished 

 by Mueller) of the plants collected, at the end of the Journal. 



It is, however, recorded twice in botanical literature, viz.:: 



1. "Report on Horn Exped. (Botany)" p. 155, March, 

 1896. Name only, and "West of McDonnell Range 

 (Tietkens)." 



2. W.A., Skirmish Hill, Mueller and Tate, "Report on 

 Botany of Elder Expedition." (Trans. Roy. Soc. S.A., xvi,. 

 351, June, 1896). 



As I could not find any published record of the variety, 

 I wrote to Professor Ewart of the Melbourne Herbarium,, 

 and he informed me that he also cannot trace any, 



Affinities. 



1. With A. oxyclada B\v.M. Both species have narrow 

 phyllodes (those of ^L. oxyclada are the narrower), and each 

 has a short central mucro, close to which is a central cir- 

 cular gland, (apparently not common in the genus), but the 

 phyllodes of A. oxyclada are glabrous and those of A.. 

 Basedowii slightly pubescent. The flowers are very differ- 

 ent, the calyx, with very hairy upper portion, being long 

 and conoid, that of A. oxyclada being short and very much 

 shorter in comparison with the petals than is A. Basedowii* 

 The pod of the latter is unknown. 



2. With A. erinacea Benth. The phyllodes of the two 

 species are different in shape, those of A, erinacea being 

 obovate-oblong or lanceolate, with a very small gland about 

 half way up on the curved margin. The flowers in A*
