NOTES ON ACACIA. 491 



referred to as the Macanally Range, fifteen to twenty 

 miles from Oooma. The Tombong locality is fifty miles to 

 the south. Between Tombong and the Macanally Range 

 is the course of the Snowy River, and the species will 

 doubtless be found along its course. 



I have chosen the specimens J. L. Boorman, 25th Sep- 

 tember, 1913, as the type, because I have adequate material 

 of it, and name the species in honour of John Luke Boor- 

 man, Collector on the staff of the Botanic Gardens, Sydney. 



Affinities. 



Its affinities must be uncertain until such time as the 

 pods are available, but I have waited over seven years for 

 them, and feel, after due consideration, that the species is 

 undescribed. 



1. With A. linifolia Willd. A. linifolia has the phyllodes 

 more sparse, the flowers fewer in the head, and the pedun- 

 cles and pedicels longer. The corolla is proportionately 

 longer than the calyx. The inflorescence of A. linifolia is 

 cream-coloured, not yellow; the plant is more wand-like. 

 Variations in the phyllodes appear to be owing to environ- 

 ment; I do not notice any fundamental differences in these 

 organs. 



A. Boormani is a plant of cold regions (Monaro); A. 

 linifolia comes from warmer localities, the Hunter to the 

 Picton districts. Nevertheless, in the present state of our 

 knowledge, it would appear that A. Boormani comes closest 

 to A. linifolia. 



2. With A. decora Reichb. A good deal of the northern 

 New South Wales material of this species has very narrow 

 phyllodes, (Cf. figs. L and M of plate 169 of my "Forest 

 Flora of New South Wales,") but the shape of the phyllodes 

 and the structure of the flower are different.
