half long, on short leafy branches ; the scales pale yellow, obtuse, hairy on the inside and 

 below the middle ; the upper part smooth on the outside. Stamens mostly 5- Fertile aments 

 an inch long, rather loose. Ovaries slender, with a long tapering beak : lobes of the stigmas 

 oblong. Mature capsules with ovoid base and a conical beak. 



Banks of rivers which are frequently overflowed ; not uncommon. Fl. Middle of May. 

 Fr. June. A very handsome willow ; nearly allied to S. pentandra of Europe, and perhaps 

 not distinct from that species. 



9. Salix nigra, Maishall. Black Willow. 



Leaves lanceolate, very acute, serrulate, smooth and green on both sides , the petiole and 

 upper side of the midrib woolly ; stipules small, lunate, caducous ; aments appearing with 

 the leaves ; scales oblong, very villous ; stamens 3-6, bearded at the base ; ovaries oblong, 

 smooth, their pedicels about one-third the length of the scales ; stigmas short, 2-lobed, nearly

A tree of the height of 15 or 20 feet, and sometimes a foot or more in diameter, with a 

 dark rough bark. The branches are very brittle at the base, but the small twigs are tough, 

 and of a purplish or sometimes yellowish color. Leaves about three inches long and half 

 an inch wide, with a long slender point, finely serrulate, pubescent when young, but smooth 

 when fully grown, except the petiole and along the midrib on the upper side. Stipules broadly 

 lunate or semiorbicular, serrate. Sterile aments 1^ - 2i inches long. Scales oblong, obtuse, 

 villous all over. Stamens mostly 5. Fertile aments 1-1^ inch long, slender. Capsules with 

 a long obtuse conical point from an ovoid base ; their pedicels finally more than half the length 

 of the scale. 



Banks of rivers, and in low grounds ; frequent. Fl. About the middle of May. Fr. June. 

 After a careful examination of S. falcata, I cannot find sufficient characters for keeping it 

 separate from S. nigra. The form of the leaves is not constant, for they are by no means 

 always falcate. 



10. Salix longifolia, Muhl. Long-leaved Sand Willow. 



Leaves lanceolate-linear, elongated, acute at each end, nearly sessile, remotely denticulate 

 with salient teeth, green on both sides and finally almost smooth ; stipules small, lanceolate ; 

 aments expanding with the leaves, on villous leafy peduncles, sometimes androgynous ; scales
