small persistent scales. The branchlets are coated at first with thick pale tomentum ; as this disappears 
they become dark orange-color, and in their first winter they are puberulous and marked by many minute 
dark spots, and at the base by the conspicuous ring-like sears left by the falling of the inner bud-seales ; 
they are ashy gray in their second year, and are slender, often contorted or zigzag, smooth, and usually 
unarmed, although sometimes furnished with slender ashy gray or very rarely chestnut-brown straight

broad winged petioles, generally incisely lobed, and sharply and usually doubly serrate except at the 
base with broad spreading teeth sometimes tipped towards the lower part of the blade with minute 
glands which occasionally appear also on the petioles; they are thin but firm in texture, gray-green, 
coated with pale persistent pubescence on the lower surface, puberulous and ultimately glabrous on the 
upper surface, conspicuously reticulate-veined, with broad midribs and primary veins, from two to five 
inches in length and from an inch to three inches in breadth. The stipules are linear, acute, minutely
