362 NOTES FROM THE BOTANIC GARDENS, NO. XI., 



is taller, hirsute with grey hairs, and has broad leaves, while our 

 new species has narrow clustered leaves and silvery-white young 

 branches, very attractive in the new growth. The clustered 

 appearance of the leaves is caused by the short lateral branchlets 

 being often reduced to a mere cluster of leaves, very much as in 

 Hihherlia fasciculata R.Br., a peculiarity not shared by P. Hart- 

 manni, whose lateral branchlets are often very short, but not 

 reduced to such an extent. 



The habitat of our new species is also very similar to P. Hart- 

 manni, and suggests that it may be the southern form of that 

 species. P. cinerascens is fairly common on the tops of hills near 

 Warialda; while P. Hartmanni has been collected by Mr. Boor- 

 man on the tops of granite hills between boulders of rocks near 

 Stanthorpe in Southern Queensland, and traced from there to 

 Wallangarra in Northern New South Wales. When the moun- 

 tainous country intervening between W^allangarra and Warialda 

 is thoroughly botanically explored, a connecting link between 

 the two species may yet be found, unless it has died out. 



Acacia doratoxylon A. Cunn. var. ovata, var.nov. 



Stanthorpe, Southern Queensland (J. L. Boorman; July, '0-4) : 

 Howell, N.S.W. (J. H. Maiden and J. L. Boorman; Aug. '05). 



A low spreading shrub not exceeding 2 feet in height, with 

 densely intricate branches. Flowers in short ovate heads, often 

 almost globular, rarely in short but distinctly cylindrical spikes. 

 Seeds shorter than in the typical A. doratoxylon, and with a 

 more compact arillus. All other characters are those of the 

 type. 



This well-marked variety seems to be confined to the granite 

 rocks capping the tops of many hills in the northern New England 

 district. It grows in dense masses along the fissures of the rocks, 

 forming in many places almost the only vegetation of the bare 



rocks. 



Acacia Gnidium Benth. var. latifolia, var.nov. 



Gilgandra (No. 1132; R. H. Cambage; Oct. '04). 

 A viscid shrub locally known as " Motherumbung, '* distin- 

 guished from the type only in the broader phyllodia. Leaves
