SALICACE^E. 



Salix. 



hairy, mostly retuse or toothed at the summit, in the fertile aments nearly as long as the ovary ; 

 stamens 2 ; ovaries lanceolate, pubescent ; stigmas large, sessile, 2-parted. — Muhl. I. c. t. 6.

This shrub is usually about two feet high ; but in favorable situations, according to Dr. 

 Barratt, it occasionally rises to the height of from 8 to 12 feet : the stems or branches often 

 prostrate, and rooting extensively. The bark is purplish brown, grayish-pubescent on the 

 young twigs, but smooth late in the season. Leaves on the long upright shoots 3-4 inches 

 long, smaller on the short suckers which arise from the prostrate stems, at first sparsely 

 clothed with short appressed grayish hairs, tapering at the base and nearly sessile ; the margin 

 furnished with minute sharp projecting teeth, which are tipped with a black gland. Sterile 

 aments an inch and a half in length, cylindrical ; the scales broadly obovate and moderately 

 villous all over. Stamens about half the length of the scale : filaments hairy below : anthers 

 yellow. Fertile aments an inch long, loose ; the scales naked at the tip. Ovaries on short 

 pedicels. 



Banks of rivers. Rochester {Prof. Dewey). Fl. Early in May ; sometimes flowering 

 again from the ends of the twigs late in the season. The sterile plant only was found by 

 Prof. Dewey. The favorite situation of this species is the drifting sand of rivers, in which it 

 spreads extensively and rapidly ; so that Dr. Barratt has recommended it for protecting sandy 

 embankments. 



****** Albje, Borrer. Aments loose. Stamens 2. Ovaries smooth. Leaves lanceolate, serrate, silky-pubescent underneath ; 



the serratures glandular. — Trees. 



11. Salix vitellina, Linn. Yellow Willow. 



Leaves lanceolate, with glandular serratures, acuminate, tapering at the base, more or less 

 silky-pubescent underneath and often also above ; aments accompanying the leaves ; ovaries 

 lanceolate, sessile, smooth, about the length of the scale; style short ; stigmas 2-lobed. —

 Sal. no. 24. 



A large tree (30 - 40 feet high) ; the branches numerous, rather erect ; the twigs yellowish, 

 smooth and shining. Leaves 2-3 inches long and 6-8 lines wide ; the young ones often 

 obtuse, at first silky both sides, but finally smooth above, silky and glaucous underneath : 

 petioles about one-third of an inch long. Stipules minute, lanceolate, deciduous. Sterile 

 aments not seen. Fertile aments 1-2 inches long, on peduncles or short branches which 

 are leafy at the base. Scales ovate-lanceolate, acute, hairy, mostly a little longer than the 

 ovaries. 



About houses and in wet meadows ; introduced from Europe, and now common throughout 

 the United States. Fl. May. Fr. June. Koch unites this species with S. alba.
