A large tree, sometimes attaining an enormous size. " I have seen them 30 feet in girth, with a 

 barrel of almost 100 feet. They are generally 15 or 16 feet in girth. Known locally as ' Mountain Gum ' 

 or ' White Gum.' The trees present a remarkable appearance. During early spring the bark is quite 

 white, but later this changes to a vivid red (sometimes almost vermilion), and the trunks have the appearance 

 of being painted in large irregular blotches. Timber pinkish in colour, and dries irregularly." (W. A. W. 

 de Beuzeville.) 



Branchlets angular, juvenile leaves scabrous in the earliest stage, pale-coloured, cordate to orbicular 

 or ovoid, stem-clasping, sessile, or with very short petioles, with a short innocuous point: 5 cm. long and 

 5 cm. broad are average dimensions. Venation spreading, reticulated, the leaf dotted with black spots, 

 scarcely seen with the naked eve. 



Mature leaves petiolate, lanceolate, usually more or less falcate, rarely under 1 dm. long and 2 cm. 

 wide, venation spreading, intra-marginal vein distinctly removed from the edge ; black-dotted. 



Inflorescence axillary, petioles flattened, under 1 cm. long, supporting three shortly pedicellate 

 appre3sed, rarely cruciform, flowers of medium size. The buds with cylindroid calyx-tube, angled, with a 

 conical operculum of equal length. C'ommisural rim marked. Anther small, opening in parallel slits. 

 Gland at the back. 



Fruits truncate-ovoid, about 8 mm. in diameter, rim rounded or flat-topped, not broad, valves three 

 or four, moderately exsert. 



Named in honour of Richard Dalryniple Hay, Chief Commissioner of Forests of New South Wales, 

 whose name will ever be connected with his arduous endeavour*, extending over a number of years, to place 

 the working of the forests of New South Wales on a sound basis.
