110 J. H. MAIDEN. 



Bentham, who edited Mueller's paper, added, — "Acacia 

 delibrata All. Cunn. ex Benin, in Hook. Lond. Journ. Bot. 

 i, 374, var. ? " He also made the following note: — 

 , ["The specimens Nos. 95 and 96 are in young seed, and 

 Cunningham's are out of flower with a loose fruit ; but, as 

 far as these materials admit of identification, they appear 

 to belong to the same species; the phyllodes are, it is true, 

 longer and not so coriaceous; but so they are in some of 

 Cunningham's specimens. Dr. Mueller's specimen No. 91 x 

 from Fitzmaurice River, is exactly like one of Cunningham's 

 except with rather more coriaceous phyllodia; it is in good 

 fruit, and the pod similar to Cunningham's. The speci- 

 mens Nos. 71, 90, and 92 1 came from Sturt's Creek, No. 25 1 

 from Roper, No. 40 * from Seven Emu River, and No. 93 l 

 from Lower Victoria River, have still more coriaceous 

 phyllodia, and, in the case of the two last, considerably 

 shorter; but they probably all belong to one species."] 



In the key in B.Pl. n, 317 Bentham contrasts A. delibrata 

 with A, oligoneura in the following words (I leave out 

 reference to the pods, as those of A. oligoneura are 

 unknown). 



Phyllodia sprinkled with a few hairs delibrata 



Phyllodia very glabrous, the smaller veins 

 between the three principal nerves 

 scarcely conspicuous oligoneura 



At p. 405 he gives a description of A. oligoneura and 

 adds, "possibly the same as A. delibrata." The original 

 descriptions tell us of the phyllodes, the remarkably short 

 spikes, and the calyx. The petals are not described, nor 

 was the pod seen. 



1 Op. cit., p. 138 attributed to A. delibrata by Mueller. At p. 139 

 remarks on these and other numbers, with some doubt, are made by 

 Bentham, Nos. 25 and 93 are, however, A. plectocarpa A. Cunn., var. 

 according to specimens in the Kew Herbarium (A. Hammondi n. sp., of 

 the present paper). See p. 95.
