the National Herbarium, from the Blue Mountains, was collected 

 by the late Mr. E. Betche, and is labelled Blue Mts., without 

 specific locality. 



Acacia trinervata Sieb.,[Thc centre of activity of this species 

 is in the neighbourhood of Springwood, thence westerly to Fal- 

 conbridge, and northerly to the "Kurrajong." A fine plantation 

 may be seen on the Windsor Road, about three miles from 

 Springwood. The writer recently found three isolated plants on 

 a rise a few hundred yards east of the present Glenbrook Rail- 

 way-Station; and Mr. R. H. Cambage has collected specimens 

 below Wilberforce near Windsor]; A. asparagoides A. Cunn,.(2), a 

 species which is more widely diffused than has hitherto been 

 suspected [Its general appearance, when not in flower, is so similar 

 to its ubiquitous congener, A. juniperina Willd., that it has 

 undoubtedly been permitted to pass as that species by many 

 collectors, for it is common on both sides of the Bathurst Road 

 between Medio w and Blackheath (These Proceedings, 1910, 

 p.414); and there are many clumps of these shrubs on the higher 

 elevations between the type-locality (Regent's Glen, Went worth 

 Falls) and Eskbank]; A. pumila Maiden k Baker, (2), Falcon- 

 bridge, Lawson, King's Tableland, Mt. Victoria, a dry-ridge 

 xerophyte; A. oxycedrus Sieb., Falconbridge; A. Baueri Benth., 

 var. aspera Maiden & Betche, King's Tableland, a dry-ridge 

 xerophyte; A. hispidula Willd., Blaxland to Linden; A. falcata 

 Willd. ,(2), Nepean to Glenbrook; A. penniiiervis Sieb.,(l), (2), 

 Wentworth Falls, a form of this variable species was collected 

 near the commencement of the descent of " Brown's Gap" into 

 the valley of the Lett, and again at about the same elevation 

 on the ascent from the valley at Hartley Vale; A. ohtusata Sieb., 

 on the roadside. Bell to Mt. Wilson, about two miles from Bell 

 Railway-Station, a few isolated plants; A. obtusata Sieb., var. 

 Hamiltoni Maiden k Betche, Leura, Bell, Mt. Wilson, Newnes 

 Junction; A. rubida A. Cunn.,(2), Glenbrook Lagoon, west to 

 Blackheath, in swamps and on the banks of watercourses; A. 

 Dorothea Maiden, Leura and Mt. Victoria, thence west beyond 

 Eskbank, the chief stronghold of this species and of A. obtusata 

 var., with which it is frequently found associated, being at
