A tree, twenty to thirty feet in height, with a straight trunk sometimes a foot in diameter, gener- 
ally dividing, four or five feet from the ground, into slender and usually upright branches which form 
a handsome oblong or occasionally a round head; or often much smaller and sometimes only a broad 
spreading bush. The bark of the trunk is light brown and an eighth of an inch thick, the generally 
smooth surface being broken into long persistent scales. The branchlets are slender, often zigzag, 
glabrous, pale orange-brown when they first appear, bright chestnut-brown and lustrous and marked by 
small lenticels in their first winter, and ultimately dark gray or reddish brown, and are armed with 
slender sharp spines an inch and a half to two inches in length; these, which sometimes terminate 
sterile lateral branches also, are bright chestnut-brown at first and finally, like the bark of the branches, 
gray or red-brown. The winter-buds are one sixteenth of an inch long and are protected by obovate 
apiculate light brown lustrous scales rounded on the back. The leaves are broadly ovate to triangular, 
acute at the apex, truncate, slightly wedge-shaped or cordate at the base, incisely three to five-cleft or 
three-lobed, and sharply serrate except at the base with acute or spreading often glandular-tipped teeth ; 
they are subcoriaceous, dark green and lustrous above and pale below, glabrous except for a few decidu- 
ous hairs on the upper surface when they unfold, or rarely pubescent on the lower surface, especially on 
the conspicuous orange-colored midribs and primary veins; they are one and a half to two inches long 
and an inch to an inch and a half broad, and are borne on slender terete petioles three quarters of an 
‘inch to an inch and a half in length. The stipules are lanceolate, acute, entire, half an inch long, and 
caducous. The leaves turn very late in the autumn bright scarlet and orange before falling. The 
flowers, which open in the last days of May after the leaves are fully grown, are produced in few- 
flowered spreading slender-branched corymbs with lanceolate acute minute bracts and bractlets mostly 
caducous before the expansion of the flower-buds. The calyx is broadly obconie and glabrous, with 
short or nearly triangular persistent entire lobes abruptly contracted at the apex into minute points, 
pubescent on the inner surface, bearded on the margins, and much shorter than the obovate white petals ;
