NOTES ON ACACIA. 91 



"Glabrous, subglaucescent, branchlets angular, sub- 

 triquetrous, phyllodes falcate-lanceolate, base and apex 

 tapering, finely striate, many nerved, spikes elongated- 

 cylindrical, interrupted, calyx sinuate-dentate, three or 

 four times shorter than the corolla, 1 pod straight, linear, 

 smooth, marginate, coriaceous, glabrous, valves more often 

 bulla te-flexuose. Phyllodes and flowers of A. leptocarpa.* 

 Spikes longer, rather interrupted. Pod 3 — 4 lines broad* 

 Cambridge Gulf and Sims's Island, N.E. Coast. Cunning- 

 ham." 



(Cambridge Gulf is N.W. Coast, and Sims's Island is near 

 the Goulburn Islands, Northern Territory). 



It is not referred to by Mueller in his paper on Northern 

 Territory Acacias in Journ. Linn. Soc, in, 114 (1859), but 

 Bentbam, in B. PI. ii, 408, in quoting some specimens 

 collected by Mueller, obviously refers to those collected at 

 the same time as those described in the Linnean Society 

 paper, although numbers are not quoted. Of course, all of 

 the specimens examined by Bentham may not be typical. 



Bentham redescribed the species in B. Fl., n, 408, and 

 what he says has enhanced value, because he edited Cuu- 

 ningham's original description. He says "Calyx short, 

 minutely toothed. Petals smooth.' ' Of A. lept oca rpa he 

 says, (op. cit., 407), "calyx short, sinuate-toothed. Petals 

 smooth, united at the base," making no reference to the 

 calyx of either species being "three or four times shorter 

 than the corolla." 



Sir David Prain has had the kindness to present to the 

 National Herbarium, Sydney, portions of the co-types, viz. r 



x This seems to be overstated, as it appears to be always half the 

 length (and therefore twice shorter) of the corolla. See below, p. 92. 



8 At p. 376, Bentham describes those of A. leptocarpa as "Phyllodes... 

 4-6 inches long, 4-5 lines broad, very much bowed, narrowed into 

 rather a long petiole. Spikes 1 - 1| inches long, flowers distinct/' In 

 A. leptocarpa the spikes are " somewhat interrupted," and the calyx "many 

 times shorter than the corolla."
