A tree, with bitter aromatic bark and leaves, sometimes attaining a height of one hundred feet, 
with a stout straight trunk four to five feet in diameter, and small horizontal branches which form a 
narrow oblong head ; usually much smaller and occasionally, toward the northern limit of its range, of 
shrub-like habit. On fully grown trunks the bark varies from one half to three quarters of an inch in 
thickness and is broken by reticulated fissures into small irregular plates, the surface of which splits 
into thin persistent scales; it is dark red-brown, or in southern Florida and the coast region of the Gulf 
states is light gray. The branches are slender and rather rigid, and at first are pale green or bronze- 
green and glabrous; they soon turn bright red or dark brown tinged with red, and in their first winter 
are red-brown or gray-brown and marked by minute pale lenticels. In the second year the thin tough 
layer of outer bark is bright red and more conspicuously marked, and may be separated readily in hori- 
zontal bands from the brilliant green inner layer. The winter-buds are obtuse or on sterile shoots acute, 
and are covered with bright chestnut-brown broadly ovate scales keeled on the back and apiculate at 
the apex; those of the inner ranks are persistent on the growing shoots scarious at maturity, acumi- 
nate, and from one half to two thirds of an inch in length. The leaves are oval, oblong, or lanceolate- 
oblong, gradually or sometimes abruptly acuminate, or rarely rounded at the apex, wedge-shaped, or 
occasionally rounded at the base, finely serrate with appressed incurved callose teeth, and furnished at 
the very base of the blade or at the apex of the slender terete petioles with one or more dark red con- 
spicuous glands; while young they are slightly bearded along the midribs on the lower surface, and are 
often bronze-green, and at maturity they are glabrous, subcoriaceous, dark green, and lustrous on the 
upper, and paler on the lower surface, two to five inches long, and an inch to an inch and half broad, 
with narrow conspicuous midribs deeply grooved on the upper side, and slender veins. The stipules 
are lanceolate, acuminate, glandular-serrate, from one half to three fourths of an inch in length, and 
early deciduous. In autumn the leaves turn clear bright yellow before falling. The flowers, which are
