58 NOTES ON NATIVE FLORA OF NEW SOUTH WALES, VI., 



Banksia integrifolia, White Honeysuckle, is typical of this- 

 sandy granite formation, and was noticed up to 30-40 feet high. 

 As regards geographical distribution this is a most interesting 

 species. In the Sydney district it appears to be almost entirely 

 restricted within a narrow strip along the sea-shore, seldom 

 extending back from the ocean or salt estuaries more than a few 

 miles. It does not appear to be common on the Blue Mountains,, 

 though it occurs there, sometimes in a stunted form. In going 

 inland from the North Coast, however, it seems to altogether 

 disregard its shore-loving tastes, and gradually works its way up 

 to the New England plateau, using these sandy granite areas as 

 stepping stones, until it crosses the Great Dividing Range to the 

 locality now described. At an elevation of 3,600 feet, and quite 

 removed from ocean-influence, it is growing as luxuriantly as 

 those ornamental representatives at Kurnell and Narrabeen. It 

 would therefore seem that the distribution of this species is to 

 a greater extent governed by the chemical constituents in the 

 soil than by the consideration of either climate or aspect. The 

 juvenile foliage was noticed around Torrington to be truncated 

 and serrated similar to that growing at Narrabeen, while the 

 mature leaves were practically entire. B. collina was found as 

 shrubs about 3-5 feet high in wet flats at Torrington. 



Another tree typical of this granite area is Casuarina suberosa 

 (Black Oak), and it occurs abundantly at elevations exceeding 

 3,600 feet. Cones were collected up to \\ inches long. 



Dendrobium speciosum (Rock Lily) seems rare, only a few 

 plants being seen in the cleft of a large granite rock; but even 

 these were scarcely expected in a locality so far removed from, 

 coastal influence. 



Davallia pyxidata (Hare's-Foot Fern) also came somewhat as 

 a surprise for the same reason, but this species was more plentiful 

 than the Rock Lily. 



In These Proceedings for 1906,(p.63) Mr. J. H. Maiden, F.L.S., 

 has described the flora of Howell, south of Inverell, where the for- 

 mation is also an acid granite, perhaps containing a slightly higher 

 percentage of silica than the rocks at Torrington. After allowing:
