" Amongst the tallest of the tropical species, occasionally reaching a height of 80 feet." 



Particulars as to habit, bark, and timber, not available. 



[The following is supplementary information from Mr. Fitzgerald's MSS. " Height 40-70 feet, 

 trunk to 30 feet, diameter li-2i feet, bark persistent, white to greyish-white, smooth; timber reddish, 

 not very hard or tough. — Quoted by Maiden in Journ. Roy. Sac. N.S.W., li, 450, 1917.] 



Jnvenile leaves. — The following description has been drawn up from specimens in the 

 flowering (or rather plump bud) stage; they represent, as far as we have them at present, the juvenile 

 leaf stage ; at the same time, they are mature to the extent that they are contemporaneous with the 

 inflorescence. Opposite, almost stem-clasping, the petioles being very short or absent; very broadly 

 lanceolate to nearly ovate, cordate at the base, apex blunt pointed, margin sometimes undulate, pale 

 coloured, or entirely glabrous. Length 8-12 cm., width 6-7 cm. 



Venation spreading, the principal veins roughly parallel, and making an angle of apjiroxiinately 

 60 degrees with the midrib ; the margin thickened, the intramarginal vem well removed from the edge, 

 the venation distinct, particularly on the lower surface. 



[From additional material collected by Mr. Fitzgerald, the following additions to the description 

 have been drawn up : — 



Juveililo leaves. — Slightly glaucous, equally green on both sides, slightly stem-clasping 

 around a nearly terete branchlet, oval to ovoid or broadly- lanceolate, tapering into a blunt or rounded 

 apex, up to 18 cm. (say 7 in.) long by 8 cm. (say 3J- in.) broad, secondary veins roughly parallel, at an 

 angle of about 60 degrees with the midrib and with abundance of fine anastomosing veins, the intramarginal 

 vein well removed from the edge. — Maiden in Journ. Roy. Soc. N.S.W., li, 450, 1917.] 



Mature leaves. — (Petiolate, alternate, lanceolate, falcate, with petioles of 2 cm., and leaves 

 up to 16 em. long and 4 cm. wide. Venation distinct, the foliage pale-coloured and glabrous and the two 

 surfaces scarcelv to be distinguished from each other.)
