Port Jackson A. lini folia when growing (J. L. Boorman). 

 No. 3 differs from A. Pilligaensis in the glabrous or non- 

 hirsute branchlets and peduncles, and in the broader (more 

 spathulate) phyllode. The phyllode of No. 3 is longer than 

 that of Nos. 1 and 2. 



A ffinities. 



1. With A. uncinella Benth. Although the phyllodia 

 are described as mostly about 1 inch long, I have seen a 

 specimen collected by Maxwell, and determined by Ben- 

 tham, with phyllodes of the same length, and remarkably 

 similar in appearance, to those of the type of A. Pilliga- 

 ensis, They are also appressed to the stem as sometimes 

 seen in .4. Pilligaensis. The structure of the flowers of 

 the two species is, however, very different, the sepals of 

 A. uncinella being narrow-spathulate. I have not seen pods. 



Only one specimen of A. uncinella, the type, is known, 

 and it is very desirable that we should collect it again. 

 Prof. Ewart has lent me the original, and it bears the label 

 "Rocky places, west tributary to Oldfield. One to two 

 feet, low shrubby plant (Maxwell)." Augustus Oldfield 

 was Mueller's collector, but the reference seems to be to 

 a river or creek. Maxwell only collected for Mueller on 

 the south coast of Western Australia. 



2. With A. ericifolia Benth. The phyllodes of A. erici- 

 folia are always shorter and often broader, sometimes 

 almost spathulate, and with less persistent stipules. The 

 calyx has narrow-spathulate lobes; those of A. Pilligaensis 

 are short and broad. The pods of A. ericifolia are narrow 

 and tend to be circinate. 



3. With A. juncifolia Benth. A. Pilligaensis has 

 probably been distributed a good deal as A. juncifolia; 

 certainly some of it has been so named by me. This partly 

 arose from confusion as to what A. juncifolia really is; I 

 have tried to set the matter clear in Ewart and Davies'
