towards the base than those from Eyre Peninsula and 

 Kangaroo Island, and the pod is broader (4-5 mm. as against 



3 mm.). 



A. retinodes, Schlecht. The phyllodia vary from linear- 

 lanceolate and *3-5 mm. broad to oblanceolate and 6-12 mm. 

 broad. In maritime forms from Wedge Island and Beachport 

 they are thick and rigid, with a breadth of 10-25 mm.

A. Menzelii, J. M. Black. Through the kindness of Miss 

 A. McMahon, school teacher at Monarto South, pods and seeds 

 of this species have now been obtained, and are figured on 

 plate v. The pods of A. Menzelii are linear, straight or 

 curved, 25-45 mm. long, 2-3 mm. broad, the valves viscid- 

 pustulate; the seeds black, shining, oblong, 4 mm. long by 

 1^ mm. broad, the last 2 folds of the funicle swollen into a 

 large, fleshy aril. They show a close relationship to those of 

 A . rigens and A . Bynoeana, but the pod of Menzelii is much 

 straighter and the seeds are narrower. 



A. Bynoeana, Benth. After reading the original descrip- 

 tion of A. Wilhelmiana, F. v. M., in Trans. Phil. Soc. Vic, i., 

 37 (erroneously quoted as "A. Wilhelmsiana" and the refer- 

 ence as "Trans. Phil. Inst. Vict," in Fl. Aust., ii., 339), I have 

 no doubt that this species is the same as A. Bynoeana. Mueller 

 describes it as having "phyllodia incurved, upright, short, 

 linear, filiform, compressed, ending in a broader, blunt, 

 recurved apex, above or on both sides furrowed and furnished 

 with 2 thin veins." This description agrees with A. Bynoeana 

 and not with A. calamifolia, of which Bentham wished to make 

 it a short-leaved variety. Besides A. Wilhelmiana comes from 

 the "mallee scrub on the Murray, where it was first discovered 

 by Mr. Wilhelmi," and that is just the locality where A. 

 Bynoeana is found. This identification, if corroborated by 

 examination of the types, would entail no change of name, as 

 A . Bynoeana has the right of priority by at least one year. In 

 specimens from Loxton and Karoonda the phyllodes are flat 

 and 2-3 mm. broad, much resembling those of A. sclerophylla, 

 but the latter has the phyllodes v/ith 3 prominent nerves and 



4 faint intermediate ones on each surface, while those of 

 A . Bynoeana have 2 prominent nerves and (in the broad-leaved 

 form) 2-3 faint intermediate ones, and the mucro is curved at 

 a more acute angle.
