Trees. 186 The Willows to be the most reliable feature to distinguish the tree from the Black willow. The leaves are narrowly lanceolate, finely toothed, bright green above, rather paler on the under side than those of Salix nigra Marshall, 5 to 12 cm. long, their slender stalks 5 to 10 mm. long, their stipules small and early deciduous. The catkins appear in early spring on short, leafy twigs of the season, are 5 to 7 cm. long, and densely many-flowered, their bracts blunt and very hairy; the staminate flowers have from 3 to 5 stamens with filaments hairy toward the base; the pistillate flowers have a smooth, conic-ovoid ovary with nearly sessile notched stigmas. In fruit the pistillate catkins become 8 cm. long or less, the capsule about 5 mm. long, its slender stalk less than half as long and several times longer than the gland. 4. WARD'S WILLOW â Salix longipes Andersson Salix Wardi Bebb Ward's willow is a small tree, or often a mere shrub, occurring on gravelly river-shores and river bottoms, from Maryland to Kentucky and Missouri, south to Florida, Texas, New Mexico, and apparently into Chihuahua; it attains a maximum height of about 10 meters, with a trunk 2 dm. in diameter, and was formerly regarded as a variety of Salix nigra Marshall. Its bark is thick, brown, rough, broken into angular plates; the young twigs are more or less densely hairy, or quite smooth, reddish brown, becoming gray to brown; the winter buds are brown, pointed, shining, about 2 mm. long. The leaves are lanceolate to ob- long-lanceolate, some of them occasionally oblanceolate, 6 to 17 cm. long, i to 3 cm. wide, finely or rather distantly toothed, varying to almost entire-margined; they are bright green and smooth on the upper side, pale and glau- cous and often quite hairy on the under side; their slender, hairy, or smoo
