the southern end of the Flinders Range. The people north 

 of Oodnadatta call the tree in question the Native Willow,' 

 and there is a 'Willow Well/ so named from two of these 

 fine trees growing close by." I may add that the specimens 

 brought back by Capt. White from Dalhousie Springs and 

 Oodnadatta have the pod of .4. varians, and in his field notes 

 with reference to the same he says: — 'The Native Willow 

 grows into quite a tree, 40 feet or so high, with very elegant 

 drooping foliage, and is always found where there is 

 moisture." 



A. salicina, Lindl. The 'Umbrella Bush," at least as 

 regards its more compact forms. Always a shrub, although 

 sometimes a large one, usually 2-4 m. in height; all the 

 branches rigid, the lowest ones springing from near the base 

 and their ends sometimes sweeping the ground, the branchlets 

 spreading or ascending. Flower-heads bright yellow, 1-5, in 

 numerous short racemes ; pods rigid, more or less constricted 

 between the seeds, with acute edges, and the ripe valves 

 splitting readily between the seeds. Appears to propagate 

 itself only by seeds. Grows in dry places and often in very 

 dry country, from Robe to the northern boundary of the 

 State, extending eastward to Renmark and westward at least 

 as far as Ooldea. The pods, even on the same plant, display 

 remarkable variety in the amount of constriction. A small, 

 compact, maritime form, of Kangaroo Island and Yorke 

 Peninsula and Port Lincoln, with oblong-linear leaves and 

 valves thinner and uniformly constricted between the seeds, 

 has been distinguished by Mr. J. H. Maiden as var. Wayne 

 (these Trans., xxxii., 277, and For. Fl. N.S. Wales, iv., 146) 

 with a height of 3-6 feet (1-2 m.), but it should be observed 

 that fruiting specimens from Outer Harbour and Dublin, sub- 

 mitted to Mr. Maiden and identified as var. Wayae, have 

 most of the leaves lanceolate, as in the type, while the height 

 of the shrubs at Outer Harbour is 3-4 m.. and they show 

 considerable diversity in the compact or loose arrangement 

 of the branches. The difficulty of the whole subject is some- 

 what increased by the scientific name. One would suppose 

 prima facie that the "curious willow-like acacia" found by 

 Major Mitchell near Oxley, on the Lachlan, in 1836, and 

 described by Lindley as A. salicina, was the Cooba, or Native 

 Willow, but Bentham judged his specimens of A . varians to 

 be distinct from A. salicina, and Maiden also (For. Fl. 

 N.S. Wales, iv., 146) has no doubt on the subject. It would 

 help very much to elucidate the question if some New South 

 Wales botanist or collector would follow in the tracks of 

 Mitchell and obtain, if it is possible at the present day, co- 

 types and photographs of the original plant.
