stem single, or branching near the base into several spreading 
shoots, armed with numerous branched spines: bark light gray, 
or with a decided tinge of brown, either close or slightly fur- 
towed and broken into many small, plate-like scales: branches 
ascending, clothed with light gray, smooth bark and bearing a 
few simple or branched, straight or slightly curved, chestnut- 
brown to gray spines, 2.5-6™ long; they are intricately divided 
near the summit into many short, pilose or pubescent, brown or 
dark reddish-brown branchlets, forming an oblong or occa- 
sionally round or flat-topped head: buds globular, bright 
reddish-brown, the terminal one on strong shoots displaying 
~ several spreading scales: leaves, which are full grown at flower- 
ing time, thin at first, becoming subcoriaceous, dark green above, 
paler below, ovate, elliptical, or slightly obovate, acute at the 
apex, rounded or abruptly contracted at the base into a winged 
or margined petiole, 8""-3.5™ long: they vary in size from 
those on the fertile branches, which are 2-10" long including 
the petiole, 1-5 wide, to large, broad leaves on vigorous 
Shoots, 13™ long, 8™ wide, the borders being sharply and 
irregularly serrate, or doubly serrate and incisely lobed and 
bearing, as does the petiole, a number of stalked, black-tipped 
glands near the base; the upper surface harshly and rather 
inconspicuously pubescent throughout the vegetating season, 
below more densely and permanently pubescent, especially 
along the 5-7 prominent veins: stipules lanceolate or oblong or 
on the stronger shoots foliaceous and lunate, densely glandular 
or glandular-serrate, caducous: flowers, which open about the 
first of May, disposed in few-, mostly 3-flowered, pilose corymbs : 
pedicels 1~3.5™ long, the lateral much longer than ne rae 
mediate one, bearing a densely or pectinately glandular, decia-
