A rugged shrub, or small tree, clothed with uneven
cracked bark. Branches more or less spreading, the terminal
shoot generally erect, of a glossy brown colour, before they
become too old ; when the young shoots first begin to grow
in Spring, they are clothed at the base with numerous brac-
teiform scales ; the lower ones smallest, quite rounded and
concave, and of a hard rigid substance ; those become gradually
larger and narrower upwards, but continue rigid and
concave a considerable way up ; but higher up the stem
they begin to become more inclining to membranaceous,
with their sides folded inwards, and are more or less lanceolate,
bluntish or acute ; the upper ones quite membraceous
and the longest of the whole, clothed with a short tomentum,
as are the young branches at that time, but this wears off
as they become older ; and they are then clothed with a
brownish bark. Leaves when in a young state and first unrolling
themselves, are rolled back so near the midrib that
they hide their under surface ; they are then clothed with
soft woolly pubescence, as is also the petioles ; but this
wears off when they become older, the leaves become smooth
and the petioles rugged : old leaves rigid, of a stiff leathery
consistence, blunt at the point, rounded at the base, of a
dark blackish green on the upper side, which is deeply
channelled down the midrib, as are also the veins which
spread from there towards the margin, and with the reticulation
of the small veins, it causes a prominent rugulose
