Group 3. Phyllodes 1-nerved, covered in long weak hairs, 

 "an oblique callous mucroneat the apex," stipules minute, 

 very deciduous. 



Flower heads on glabrous peduncles not so long as the 

 phyllodes, large sheath-like bracts at the base of the 

 peduncle. Calyx narrow, irregular, free nearly to the base, 

 hairy. Petals free, glabrous, flve-merous. Pistil hoary or 

 rather papillose. 



Liverpool Plains (?Allan Cunningham); Near Dubbo (E, 

 Betche); Gulgong (F. E. Haviland). 



Group 4. Phyllodes clammy, one-nerved, a few scattered 

 hairs, minute deciduous stipules; "oblique-callous mucrone 

 at the apex," gland near base. 



Flowers in heads, on glabrous peduncles exceeding the 

 phyllodes, and with a large sheath-like bract at the base. 

 Flowers small and frail. Calyx irregularly lobed, fringed 

 with hair. Petals five-merous, glabrous. Pistil hoary. 



Bogan Gate and Wyalong (J. L. Boorman), Wyalong and 

 Temora (Rev. J. W. Dwyer). , There are two different look- 

 ing forms from Temora, one compact in habit and more 

 pubescent than usual (? A. dasyphylla A. Cunn.) the other 

 of a more open habit, the phyllodes further apart. 



I may remark that Group 3 is closely related to Group 4, 

 but the phyllodes of Group 3 are thinner in texture, and 

 have a marked nerve. In Group 4 the phyllodes are thicker, 

 with thick margins, and the nerve although present is not 

 distinct, but is lost in the thickness of the margin. 



I am of opinion that both No. 3 and No. 4 are very near 

 the type of A. lineata. It may be desirable to bring under 

 notice the original description of A. lineata, which is as 

 follows : — 



A. lineata (Cunningh. Mss.), stipulas wanting or decidu- 

 ous; phyllodia linear, ending in an oblique, callous mucrone
