Description. — A very large tree, the outer bark 
usually bleached a dark grey, but more or less blackened 
by fire ; the bark usually more or less furTowed, thick, 
fibrous but inclined to be spongy, reddish-brown, inner- 
most (living) bark bright deep yellow. Coppice (sucker) 
leaves and branch lets, or leaves and branchlets on young 
trees, clothed with stellate hairs, very dense on the branch- 
lets and petioles, more scattered on the leaf-blades. Cop- 
pice (sucker) leaves or leaves on, young trees at first 
varying from oblong to ovate-oblong, ovate or even lan- 
ceolate; up to 3 inches long, nearly as broad as long, or 
1J times as long as broad; at other times in the more 
lanceolate leaves 3 — 3A times longer than broad; all forms 
gradually tapering into the glabrous secondary or adult 
leaves, though the juvenile type may be found on trees 
up to 20 feet high; petiole mostly about 2 lines long; 
blade paler on the under than on the upper surface ; base 
rounded or more or less cuneate, oblique or less frequently 
equal; apex acuminate or gradually tapering to an acute 
apex. Secondary or adult leaves glabrous, at first often 
very broadly lanceolate, straight or more or less falcate, 
the broader leaves usually very oblique at the base, on the 
flowering twigs much narrower and usually very fal- 
cate; up to b inches long and inches broad; mostly 
about five times longer than hroad, gradually tapering 
to a long-pointed (acute) apex, base oblique and tapering 
to a slender twisted petiole of 4-f indi; lateral nerves 
and intramarginal vein rather prominent in the dried 
leaf, particularly on the under surface ; lateral nerves 
oblique; intramarginal vein J-li lines distance from the 
edge of the leaf. Flowers in pedunculate heads or umbels 
in the axils of the leaves, often on the secondary wood 
from which the leaves have fallen; peduncles inch 
long, bearing a head or umbel of 5-15 flowers. ( kilyx- 
tube obconical or more or less turbinate and contracted 
at the base into a stout pedicel ; a quarter to one-third, of 
an inch long (including the pedicel when present) ; oper- 
culum short, conical, rather blunt or more or less pointed, 
about 2 lines high. Stamens numerous, all fertile; longest 
filaments 24 lines long; anthers minute, cordate or more 
or less reniform, cells opening by longitudinal slits. Seed
