We propose the name in honour of the great Robert 

 Brown who (amongst other parts) is closely identified with 

 the botany of Northern Queensland. 



A medium sized Box-tree, about 40 feet high, erect 

 rather than drooping. 



Bark. Hard thin flaky Box-bark, on the trunk and large 

 branches, the ultimate branchlets smooth. 



Juvenile leaves. Lanceolate or narrow lanceolate. 

 Generally long and narrow, petiolate, equally green on both 

 sides, and slightly shiny, venation distinct, spreading, intra- 

 marginal vein distinct from the edge. Size say 20 x 2 cm. 



Mature leaves. Lanceolate; except as regards the size, 

 the description of the juvenile leaves applies. Size say 

 10-15 x 2 — 3 cm. Lateral veins arranged at angle of 

 about 30 degrees with midrib. 



Buds small, clavate, operculum hemispherical or slightly 

 umbonate, and about half the length of the calyx-tube t 

 which tapers gradually into the pedicel.
