RANGE. 



Bold Bluff; -Mount Rason; Packhorse, Synnot Ranges, and to the east and 

 north. In sandy soil, among sandstone and quartzite rocks. In the distance the 

 summits of the trees appear as if covered with frost. (W. V. -Fitzgerald). 



I have seen the following specimens : — 



Summit of Bold Bluff, West Kimberleys (W. V. Fitzgerald, No. 844). The 



type. Packhorse Range, West Kimberleys (W. V. Fitzgerald, No. 1,012). Mr. 



Fitzgerald says that his type came from Bold Bluff, which is very little more than an 



• in extent on rep. and that the only species of Eucalyptus he found growing 1here 



were E. collina, E. Mooreana, and E. lirata. 



Mr. Fitzgerald long before stated that E. collina is restricted to the sandstone 

 and quartzite ranges, tablelands and sandy foothills, and that the relative degrees of 

 density of growth of trees forming forests are as follows : — E. collina, E. miniata, 

 /.'. crebra (probably E. melanopMoia, see Part XII, p. 73, J.H.M.), E. tetrodenta, 

 E. microtheca. (Kimberley Report, p. 12.) 



AFFINITIES. 



1. With E. metadata Hook. 



E. collina is a Bloodwood, and has strong affinities to the rest of the Corymbosse. 

 At the same time it is smooth-barked, and hence is what would be called a Spotted Gum 

 in Eastern Australia, and hence its nearest, affinity is to E. maculata. The timber of 

 E. collina is dark brown, while that of E. maculata is pale-coloured, almost white. The 

 timber of E. collina is very hard, and Mr. Fitzgerald says the party had to cut a lot of 

 it away; the hardness and toughness of it impressed themselves on his memory. 

 Fo A', maculata, see Part XLIII, p. 84, with Plate 178. The foliage of the two species 

 is very different, and they vary in buds and to some extent in fruit. E. collina is only 

 known Erom t he t ropics of Western Australia, while E. maculata is a native of sub-tropical 

 eastern Australia. 



2. With E. Abergiana F.v.M. 



An obvious <lifference between the two species (for figure, &c., of E. Abergiana 

 see Part Xkl. p. 9, Plate 170) seems to be in the leaves, those of E. Abergiana being 

 broad, bul I confidently expect to see rather narrow mature leaves yet. The timber 

 of E. Abergiana is red. At the same time, the two species have some similarity in 

 t lie shape and size ( ,| i he fruits, whieh are. however, usually more sessile in E. Abergiana, 

 a species of whieh very little material is in existence.
