A tree, twenty-five to thirty feet in height, with a trunk twelve or fourteen inches in diameter, 
dividing, eight or ten feet above the ground, into several stout spreading branches which form a wide 
open head; or usually much smaller and sometimes barely more than a bushy shrub with rigid con- 
torted branches. The bark of the trunk is one third of an inch thick, and longitudinally fissured, the 
The branchlets are at first coated 
with thick white tomentum which soon disappears, and in their first winter are glabrous or slightly 
outer layer separating into long narrow persistent red-brown scales. 
pubescent and covered with bright red-brown bark marked by occasional small pale lenticels ; in their 
second year they develop long stout spur-like and somewhat spinescent lateral branches, and are then 
light brown. 
ous ciliate margins ; those of the inner ranks enlarge with the growing shoots and at maturity are from 
one third to one half of an inch in length, oblong, acute, bright red, and glandular-serrate. 
are ovate or sometimes almost triangular, usually acute at the apex, often truncate or subcordate, and 
The winter-buds are minute, obtuse, and protected by bright red scales with dark scari- 
The leaves 
occasionally acute at the base, incisely serrate with glandular teeth, and often three-lobed, especially on 
vigorous shoots; when they unfold they are red-bronze, coated on the lower surface with pale tomentum, 
and pilose on the upper surface ; at maturity they are membranaceous, bright green above, and paler, 
glabrous, or sometimes slightly pilose below, three or four inches long, and an inch and a half to two 
inches and a half broad, with broad midribs and primary veins grooved on the upper side, and conspicu- 
ous veinlets, and are borne on slender petioles an inch and a half to two inches in length, tomentose or 
pubescent at first but ultimately glabrous and often furnished near the middle with two dark glands. 
The stipules are filiform, acuminate, half an inch long, and early deciduous. 
when the leaves are almost fully grown, are produced in five or six-flowered umbels on slender pedicels 
The flowers, which appear 
an inch and a half to two inches in length, and are an inch and a half to nearly two inches across when 
expanded, and very fragrant. The calyx-tube is obconic, and pubescent or coated with thick white 
tomentum ; this also covers the inner surface of the long acute lobes which end in rigid subulate points. 
The petals, which are inserted remotely one from another, are white or rose-colored, obovate, rounded
