SALICACE^E. (WILLOW FAMILY.) 415 



vate, as lone; as the stalk of the densely-silky ovoid ovary ; stigma 2-lcbed, nearly 

 sessile. (S. grisea, Willd.} Sandy river-banks; not rare. Shrub 4 -10 

 high. Fertile catkins in flower f, at length 1^', long; the ovaries not spreading 

 or elongating in fruit, thus appearing sessile. 



7. S. pct.iolfs.ris, Smith. (PETIOLED WILLOAV.) Leaves lanceolate, 

 pointed, smooth above, slightly silky beneath when young, at length smooth and glau- 

 cous ; fertile catkins ovoid-cylindrical, loosely /lowered, scales very hairy, obovate, 

 scarcely as long as the stalk of the silky tapering ovary; style short but distinct; 

 stigma 2-cltft. (S. rosmarinifolia, and S. fuscata, Pursh?) Same situations as 

 the last, which this shrub resembles in some respects ; but the mature leaves are 

 not silky beneath, and dry less black : the scales are not so dark, and are clothed 

 with longer white hair. Sterile catkins like the last ; but the fertile shorter and 

 broader, the pods (at length merely downy) spreading and showing the stalks. 



*= * * Ovary sessile, woolly or silky : catkins bracted at the base : leaves not drying 



black. Small trees. 

 - Filaments united to the top, appearing like a single stamen. 



8. S. PURptiREA, L. (PURPLE WILLOW.) Leaves oblanceolate, pointed, 

 the lower somewhat opposite, smooth, minutely and sparingly toothed ; catkins 

 cylindrical ; scales round and concave, very black ; stigmas nearly sessile. (S. Lam- 

 bertiu'ina, Pursh.) Low grounds. Reco'gnized at once in the sterile plant by 

 the united filaments giving to the flowers a monandrous appearance. The twigs 

 are polished, and of an ashy-olive color. (Adv. from Eu.) 



*- H- Filaments separate. 



9. S, VIMINALIS, L. (BASKET OSIER.) Leaves linear-lanceolate, very long 

 and taper-pointed, entire or obscurely crcnate, white and satiny beneath; catkins 

 cylindrical-ovoid, clothed with long silky hair ; ovary long and narrow ; styles elon- 

 gated ; stigmas linear, mostly entire. Wet meadows. Considered the best species 

 for basket-work. Leaves 3' -6' long, of a beautiful lustre beneath. S. Smith- 

 iuna, Willd., another species of this section, differing principally in the some- 

 what broader leaves, has also been introduced, and is occasionally met with. 

 (Adv. from Eu.) 



$ 2. Catkins lateral, with 4-5 leafy bracts at the base, appearing with or before the 

 leaves in May or June : inner membrane of the scales of the flowering buds sepa- 

 rating from the cartilaginous exterior, sometimes elevated on the apex of the bursting 

 catkins: ovary stalked, smooth (under a lens minutely granular, ivith occasionally a 

 few short hairs at the base) : stamens 2 : scales dark or black, hairy, persistent. 



10. S. cordiata, Muhl. (HEART-LEAVED WILLOW.) Leaves lanceolate 

 or ovate-lanceolate, truncate or heart-shaped at base, taper-pointed, sharply toothed, 

 smooth, paler beneath ; stipules kidney-shaped or ovate, toothed, ojlen large and 

 conspicuous, of the length of the (when young downy) petiole, or sometimes 

 small and almost entire ; catkins appearing with the leaves, leafy at Vase, cylindri- 

 cal, the fertile elongating in fruit ; ovary lanceolate, tapering to the summit. 

 Var. RfoiDA has the leaves large and rigid, with coarser teeth, of which the 

 lowest are somewhat elongated. (S. rigida, Mnhl. S. Torreyana, Barratt, 

 which has leaves of a deeper green beneafh, appears to belong here.) Var. 



YRICOIDES has narrower leaves, neither heart-shaped nor truncate at the base,
