" After the 115th mile-post was passed, an undescribed species of Eucalyptus appeared (E. Brownii 

 Maiden and Cambage, these Proceedings, 1913, p. 215). The note made in the train conveys a general 

 description of the tree, and reads ; — ' A narrow-leaved Box, seems distinct species, rough baric on branches, 

 green leaves.' These trees were growing on a contorted, micaceous slate formation showing quartz, but 

 they continued intermittently to Wirra Wirra, where the rock is sandstone, possibly Upper Cretaceous. 

 This Box tree averages about 10 feet high, with small fruits, and according to Mr. Thomas Keller, of Wirra 

 Wirra, has dark-red timber." (R. H. Cambage in Journ. Roy. Sor-. N.S.W., xlix, 413, 1915.) 



SYNONYMS. 



E. bicolor A. Cunn., var. parviflora F.v.M., Burdekin River (see B.Fl. iii, 215), 

 E. populifolia F.v.M., non Hook. 



Scrub Box tree of the Burdekin River, but not the Box tree of the Suttor River, 

 labelled as above, which is E. populifolia Hook. All the above specimens were 

 examined by Mueller, and apparently by Bentham also. 



AFFINITIES. 



Its closest relations are with two species — E. populifolia Hook., and E. bicolor 

 A. Cunn. Both are indicated by the labels of both Bentham and Mueller. 



1. With E. populifolia Hook. 



To the typical form of E. populifolia the resemblance is not close, but there is a 

 narrow-leaved form of the species to which the resemblance is closer. The differences 

 lie in the bark, which is less flaky in populifolia, in the more conical fruits of E. Brownii, 

 and particularly in regard to the position of the intramarginal vein, which is much 

 more removed from the leaf edge in E. Broivnii. 



2. With E. bicolor A. Cunn. 



The differences appear to be the duller colour of the foliage of E. bicolor, that 

 of the new species being a vivid green, its less spreading venation and less conoid fruits. 

 E. Broivnii has not the weeping habit of E. bicolor. 



There is a specimen in the Melbourne Herbarium labelled " near Mount Elliott, 

 Queensland, Fitzalan and Dallachy," which appears to be E. Broivnii. The late J. G. 

 Luehmann has a note " Placed by Bentham with E. largijiorens (bicolor), seemingly 

 with injustice. F. v, Mueller."
