A tree, rarely attaining the height of thirty feet, with a short trunk eight or ten inches in diameter, 
and spreading rigid branches which form a wide open head. The bark of the trunk is from an eighth 
to a quarter of an inch in thickness, dark reddish brown, and divided by deep longitudinal fissures into 
narrow ridges, the surface of which is broken into small persistent plate-like scales. The young branches 
are clothed at first with pale pubescence which soon disappears; in their first winter they are slender 
and covered with smooth brown bark slightly tinged with red, and in their second year produce slender 
spinescent lateral branchlets, and are light brown and marked by occasional orange-colored lenticels. 
The winter-buds are obtuse, and one sixteenth of an inch long, their outer scales chestnut-brown and 
slightly pubescent, with ciliate scarious margins, the inner ones oblong, acute, coated with long pale 
hairs, accrescent with the young shoots, and a quarter of an inch long when fully grown. The leaves 
are lanceolate-oblong, acute or rounded and apiculate at the apex, acute at the base, and coarsely crenu- 
late-serrate above the middle or sometimes almost entire ; when they appear they are more or less coated 
with pale tomentum on the lower surface, and are pilose on the upper surface, and at maturity are sub- 
coriaceous, dark green and lustrous above, paler below, and glabrous or nearly so, with slender midribs 
grooved on the upper side and obscure primary veins; they are then an inch and a half to three inches 
long and one half of an inch to an inch and a half broad, and are borne on slender rigid glabrous or 
puberulous petioles from three quarters of an inch to an inch in length. The stipules are filiform, rose- 
colored, half an inch long, and caducous. The flowers, which are an inch across when expanded, and 
very fragrant, appear from the end of March in Louisiana to the middle of May in Pennsylvania, and 
are produced in few-flowered umbels on slender pedicels an inch to an inch and a half in length, furnished 
near the middle with one or more inconspicuous glands, and are glabrous or sometimes, especially in the 
Gulf states, covered with pale tomentum. The calyx-tube is glabrous, pubescent, or tomentose on the 
outer surface, with narrow acuminate lobes, terminating in rigid points, and clothed on the inner surface 
with pale tomentum. ‘The petals are distant, narrowly obovate, rounded above, contracted below into 
long slender claws, undulate and sometimes irregularly denticulate-serrate at the base of the blade, and 
white, pink, or rose-colored. The ovary and the lower part of the styles are densely clothed with pale
