NOTES ON ACACIA. 195 



Oalyx turbinate, the edge somewhat irregular and ciliate, 

 not half as long as the petals. Petals glabrous. Ovary 

 elongated, glabrous. Pods and seeds not seen. 



The type is E. Pritzel, No. 706. 



Synonym. 

 A, spinosissima F.v.M., also Diels and Pritzel, non Benth. 



Range. 

 This species has only been found in Western Australia. 

 Lake Wagin, its northern locality, is a few miles east of 

 Wagin, a railway station on the Great Southern Railway 

 150 miles from Albany (King George's Sound). Oranbrook 

 is 70 miles from Albany. The Stirling Range is a few miles 

 to the east of Cranbrook. 



A fragment given me by Mr. J. G. Luehmann of the 

 Melbourne Herbarium bears the label "Acacia spinosissima 

 Bentham" (in Mueller's handwriting), "Bunkin, near Lake 

 Wagin, W.A., Miss M. Cronin, 1890," in his own. 



With a spreading habit. In the Stirling district near 

 Oranbrook, in sandy country with Eucalyptus scrub (Diels 

 4514, Pritzel 706). Diels and Pritzel in Engler's Bot. Jahrb. 

 xxxv, p. 299). The label of Pritzel's No. 706 says, North- 

 west Plantagenet district in scrub on the sides of hills, 

 Stirling Range. 



Affinities. 



1. With A. ulicina Meissn., which seems its closest 

 affinity. Indeed its general appearance reminds one more 

 of Ulex than A. ulicina does. 



Mr. Luehmann, in sending me a piece of the Lake Wagin 

 specimen, added the note " differs from A, ulicina in the 

 short truncate calyx as well as in fruit." There is no fruit 

 in my specimen, and I suggest that, through short-sighted- 

 ness, he may have mistaken a phyllode for it.
