NOTES ON ACACIA.

rugose. Calyx narrow-lobed, free to the base or nearly so, 

 spathulate with rugose apex, thin, smooth. Petals united 

 about half way up, separating at a touch, glabrous. Pistil 

 hoary-tomentose. Pods terete, smooth, with a resinous 

 incrustation. Seeds longitudinally placed, and when ripe 

 suspended from the pods by a filiform funicle, which is 

 attached to a broad arillus. 



I have seen it from Ooolgardie (L. O. Webster). "A tall 

 shrub," Oowcowing (Max Koch, 1025, and also found mixed 

 with 1338). 132 miles and upwards, Watheroo Rabbit 

 Fence (Max Koch, 1338a). Kurrawang, near Kalgoorlie 

 (Dr. J. B. Oleland). Dr. F. Stoward, Nos. 223 and 224, no 

 localities. Bruce Rock-Merriden district (Dr. F. Stoward, 

 Nos. 8 and 14). Kunonoppin (Dr. F. Stoward, No. 75). The 

 only pods I have seen. These are identical with the pods 

 from the same place (F. E. Victor), described by the late 

 Dr. A. Morrison as A. aciphylla Benth. in the "Scottish 

 Botanical Review," April, 1912, p. 99. 



There is some danger (with flowering material) of con- 

 fusion with A. leptoneura on a casual glance, but the 

 flower-heads of the latter are uniformly spherical, while 

 those of A, filifolia are either ovoid or a little longer. The 

 young phyllodes of A. leptoneura are soft, golden pubes- 

 cent; those of A. filifolia are stiff, rugose, resinous. 



The pods and seeds display a marked difference. The 

 pods of A. leptoneura are flattish; those of A. filifolia are 

 terete. The seeds of A. leptoneura have a funicle with 

 two folds and a barely expanded arillus ; those of A. filifolia 

 have a very broad arillus, and the commencement of the 

 filiform funicle is on the opposite (the ventral) side of the 

 seed or base of arillus to that from which the attachment 

 of the funicle springs. In other words, the funicle appears 

 to cross over from one side of the valve to the other.
