NOTES ON ACACIA. 187 



Sepals spathulate, free, besprinkled with hairs, half as 

 loDg as the corolla, the floral-bract simulating a sepal 

 in shape and vestiture. Petals smooth, destitute of a 

 prominent midrib, united for about half their length. Ovary 

 densely hairy. Pod and seed not seen. 



The type was collected by Dr. H. Basedow on the " South 

 Australian Govt. North West Expedition," 1903, No. 254 r 

 and has been distributed to a limited extent as Acacia 

 cijperophylla by the finder. It came from the Musgrave 

 Ranges, Northern Territory, where A. Basedoiui was also 

 found. I have not seen a second specimen. 



Affinities. 



1. With A. prcelongata P.v.M. in Melbourne "Chemist 

 and Druggist," August 1883. This would appear to be its 

 closest affinity, and the species differs from A. prcelongata 

 in the very much longer glabrous phyllodesof that species,, 

 in the fewness of the ribs and in the racemose inflorescence. 



2. With A. Allenlana Maiden, in Ewart and Davies' 

 "Flora of the Northern Territory," p. 330, with figures. 

 A. Allenlana has much longer and fewer-ribbed glabrous 

 phyllodes with numerous conspicuous bracts and with a, 

 glabrous ovary.
