1915] BALL—WILLOWS 47 
sessile, stout; pistillate 2.5—7 cm. long; capsule subsessile, 6-8 mm. 
long, densely silvery pubescent; style about 1.4 mm. long, stigmas 
long; scales obovate, acute, black, densely pilose; stamens 2, fila- 
ments glabrous, free. 
Low shrub, probably about o.5-1 m. in height, of spreading 
habit; bark (probably) dark gray to brownish, branchlets stoutish, 
divaricate or somewhat virgate, dark brown to black, dull or some- 
what shining; smooth or sometimes longitudinally finely wrinkled, 
glabrous throughout; buds mid-sized to large, 6-10 mm. long, 
ovate, apiculate, chestnut, glabrous. 
Leaves usually exstipulate, petiolate; stipules wanting on 
fruiting branchlets, on one sterile shoot (Applegate 2758) 4-8 mm. 
long, lanceolate to semicordate, acute; petioles slender to stoutish, 
5-10 mm. long, greenish yellow or becoming brown, glabrous; 
blades on fruiting branchlets narrowly to broadly obovate or 
obovate-oval, acute to abruptly acute at the apex, cuneate to acute 
at the base, 3-6 cm. long, 1.5-3.5 cm. wide, common sizes being 
4 by 2, 5 by 2.5-3, and 6 by 2.5-3.4 cm., those on luxuriant sterile 
twigs elliptic-oblanceolate to elliptic-oval or even elliptic-oblong, 
larger, 4-8 cm. long, r.5—3.8 mm. wide, the narrowest 7 by 1.5, 
the widest 8 by 3.8 cm., all entire or distal leaves on sterile twigs 
crenate or crenulate, dark green and somewhat shining above, 
strongly glaucous beneath, midvein and primary veins rather 
prominent above, strongly so beneath, where the secondaries make 
a strong reticulation, the primaries simple, parallel, glabrous 
throughout or the under surface sparsely sprinkled with short shin- 
ing hairs. : 
Aments precocious, stout, sessile, ascending or spreading, 
loosely to closely arranged on the branchlet, the staminate naked, 
the pistillate subtended by 1 or 2 very small, scalelike leaves, the 
peduncle in fruit becoming 2-5 mm. long. 
Pistillate aments 2.5~5 cm. long in flower, becoming 3-7 cm. 
long in fruit, 1.2-2 cm. wide; capsule 6-8 mm. long, narrowly 
lanceolate-rostrate, acute, subsessile, densely pubescent with silvery 
white hairs; pedicel stout, 0. 2-o.4 mm. long, pubescent; style 1. 2- 
T.5 mm. long, entire, brown; stigmas 0.4-0.6 mm. long, mostly
