28 TROPICAL ACACIAS OF QUEENSLAND. 



Type from dry stony ridges at Beta. In flower 1st 

 Juh', 1913 (J. L. Boorman). Description of pod and seed 

 drawn up from a specimen " between Haly's and York's, 

 on the newlj' cut road, the Dawson, October, 1877 (Dr. 

 Joseph Bancroft). 



Other specimens have phjdlodia wdth lobes more 

 pronounced than the type, for example (a) Nanango (C. 

 H. Grove, No. 54). In this specimen the rhachis and 

 peduncles are covered with a short golden, silky pubescence, 

 the calyx is comparatively shorter than in the case of the 

 type, and the petals are sprinkled with hairs. 



(6) Eidsvold (Dr. T. L. Bancroft). 



(c) Copperfield (John Shirley). 



The following specimens have the leaves non-lobed, 

 or scarcely lobed, like the tj^pe. 



(d) A specimen mixed with a specimen of A. macra- 

 denia Benth. collected by Mitchell at Mt. Pluto in 1846. 



(e) Clermont (H. Salmon, No. 28). 



(/) Rockhampton (Rev. J. E. Tenison Woods, as A. 

 macradenia (?) ). 



It is confined to Queensland, so far as is known at 

 present, but it may be expected to be found in northern 

 New South Wales. 



Affinities. 



1. With A. 2)67111' nervis Sieb. 



[ A. Bawcrofti \va,s looked upon by Bailey as a form of 

 A. j)en7iinen-is, and perhaps b}^ Bent ham also]. 



A. Bancrofti has not the secondary nerve which is a 

 character in A. x>enninervis , and the lobing of the ph3'llode8 

 is absent in the latter species. The raceme in A. penni- 

 nervis is shorter and the flowers are 48 in the head. The 

 flowers in A. penninervis are narrower, the petals more 

 separate and the calyx less continuous with the corolla. 

 The pods of A. jjeniiinervis are not shining black ; the 

 sculpture of the margins is different in the two species. 

 At the same time the affinity of the two species is evident. 



2. With A. macradenia Benth. 



This has obvious affinity as already indicated as having 

 been noted by Bailey. A. macradenia has a smaller raceme 

 with the calyx-lobes separate to the base, and the curved
