334 THE FLORA OF THE NORTHERN TERRITORY 



The phyllodes are long (up to 18 cm.) and narrow-lanoeolate (under 1 cm 

 broad). 



9a. A. salicina, Lindl.,var. 



" 362. 40 miles west of Camp iv. Lander Creek, 21st June, 1911/' In 

 flower. 



" 196. Near Haasfs Bluff, Macdonnell Range, 4000 feet, 22nd May, 

 1911." In bud. 



I have received the same form from the Strelley River, North Western 

 Australia, collected by Dr. J. B. Cleland. 



A glaucous or glabrous shrub with angular branchlets. 



Phyllodes obovate-long or almost spathulate, obtuse, narrowed at the base, 

 almost sessile, the apex terminating in a short straight or recurved point. 3-4 

 cm. long, and rather more than 1 cm. broad. As many as three, and 

 occasionally four glands on the inner margin, fewer on the outer margin. 

 Texture fleshy, and in drying the phyllodes take on a pseudo -netted - 

 veined appearance. 



Flowers in not numerous globular heads, up to 20 and 25 in the head, 

 glabrous, 5 or 6-merous, racemes longer than the phyllodia. 



Calyx with nearly oblong sepals, truncate at top, sMghtly lobed and ragged 

 at the edge, scarcely thickened at the edge, central nerve visible. Sepals half 

 or a httle less than half as long as the petals. 



Petals united about half way up, sometimes spreading. 



Pistil very immature, but appears to be quite smooth. 



Bracts leafy with ragged edge. 



Pod and seed not seen 



I have described these specimens at length because they constitute a form 

 new to me. Pods are not available, but the form seems to be conspecific with 

 the very variable A. salicina, Lindl. Perhaps when pods are available it m_ay 

 be given rank as a variety. 



The following comparisons with species having phyllodes somewhat similar 

 in size and shape may be useful. 



1. With A. Watisiana, F.v. M. 



, After A. salicina, its closest affinity appears to be with this species. The 

 type of A. Wattsiana, F. v. M., comes from Broughton and Rocky Creeks, S.A. ; 

 the species is not rare in that State, and does not appear to extend to the 

 Northern Territory or Western Australia. 



The phyllodes of A. Wattsiana are thinner (and therefore do not dry 

 \\'rinkled), usually larger, and have fewer glands (being usually uniglandular), 

 flowers in the head usually fewer. 



The bract is nail-headed, but foliar in the present form. 



2. With A. bivenosa, DC. 



Principally from the North- West Coast, we have a form of A. bivenosa 

 strikingly different in general appearance from the type ; this is A. elliptica, 

 A. Cunn. (see B. Fl., ii., 381). A. elliptica is very similar in appearance to 

 the new form of A. salicina, but the second prominent vein readily separates 

 them. It is, however, to be borne in mind that in individual specimens of A. 

 elliptica (bivenosa), the second vein is sometimes so faint as to be easily passed 

 over. 



10. A. strongylophylla, F. v. M., Fragm., viii., 226. — " 144. 15 miles 

 west Hugh River, Macdonnell Ranges, 3000 feet on hills, Cth May, 1911."
