A shrub of !(► feet, hoary or silvery white with a very 

 minute pubescence : branchlets slender, angular at the tips, 

 soon becoming nearly terete. Phyllodia lanceolate, hardly 

 falcate, narrowed at each ontl. but obtuse. 5-6.5 cm. (sa^^ 

 2-2^ inches) long. 1-1.5 cm. (a!i(»ut ^> inch) broad, straight 

 or slightly oV>lique at tlie 1)ase. coriaceous and finely striate, 

 Tsith numerous fine parallel nerves all etjual or 2 or 3 rather 

 more prominent : gland at base. 



Spikes mostly in pairs, shortly pedunculate, slender, 

 up to about an inch long, rhachis glabrous, floAvers 5-merous. 

 Calyx cup-shaped Mith a sinuous ragged edge. hair^'. but 

 not quite to the edge, less than half the length of the petals. 

 Petals glabrous, united not quite half the way up. Pistil 

 hairy. Pod not seen perfectly ripe, straight, linear, 6 cm. 

 long and 2-3 mm. broad. .Seed, not seen ripe, elliptical- 

 oblong, longitudinally arranged in the pod. with a ribbon- 

 like funicle hardly forming an arilhis. 



Collected at Almaden. North Queensland. 20th August, 

 1913. (R. H. Cambage. No. 3,893). 



Affinities. 



1. With A. lejAostachya Benth. It is sharply separated 

 by the moniliform pod of the latter, and apparently also by 

 the funicle, but I have not seen seed of that species. The 

 phyllodes of A. leptostachya are narrower, and the calyx 

 less hairy. 



While both species are imperfectly known, they are 

 sufficiently distinct, although closely allied. 



2. With A. glaucescens Willd. This is a large species 

 confined to New South Wales, so far as we know at present. 

 I have described it in Part 38 of my " Forest Flora of 

 N.S.W." with Plate 145. There is a good deal of similarity 

 between A. glaucescens and the new species in regard to 

 the floral structure, but the calyx is comparatively shallower 

 and the petals hairy and not recurved in A. glaucescens.
