Description. — A large tree (or in poor siliceous soil 
sometimes little more than a shrub) with a rough fibrous 
bark, the fibres rather short and prickly to the touch; 
dark reddish brown, but the outermost layer mostly 
bleached a dark grey and commonly much blackened by 
fire; ultimate branehlets smooth. Young branchlets- 
angular but soon become terete. Coppice leaves or leaves 
on young trees opposite, ovate-lanceolate to less com- 
monly ovate, base auriculate, oblique, apex long 
and acuminate, dull green above, markedly paler, inclined 
to be glaucous beneath, 3 — inches long*, A — 1A inches 
wide, varying a good deal in proportion of length to 
breadth, in the more lanceolate leaves five times as long 
as broad, in more ovate ones only two and a half times 
as long as broad; veins and veinlets fine, clearly discern- j 
ible on the under surface, less plain above; the main 
nerves fine (mostly about 4 inch apart), intramarginal i 
vein in the narrower leaves very close to the edge, in the * 
wider ones further (up to one line) away. Ordinary - ? 
(secondary or adult) leaves coriaceous, lanceolate, usually . 
falcate, paler 011 the under than on the upper surface;! 
(usually clearly discernible even in the dried specimens),./ 
base euneate, acuminate at the apex and mostly gradually | 
drawn out to a long point; petiole J — \ inch long; blade 
up to b inches long and 1 inch wide, 5 — 7 times longer 
than broad, midrib distinct on both surfaces, lateral nerves | 
arising from the midrib at an angle of about 45deg.,- |i 
mostly clearly visible on the under surface, usually indiaH 
tinct on the upper, i — 4 inch apart, intramarginal vein 
very close to the edge, almost touching in the narrower 
leaves, about one-sixth of an inch removed in the wider 
ones. Flowers in umbels in the upper leaf axils, the 
terminal ones forming short leafless panicles; umbels 
12 — 15 flowered; peduncle rather slender, about 4 inch ] 
long; calyx tube turbinate, narrowed at the base into a j] 
distinct pedicel, calyx and pedicel together inch long; I 
operculum, conical 2 lines high; stamens in several series,* 
all perfect, the longest filaments about 2 lines long; sta- :
