SAi>iCACEiE. (willow familt.) 415 



vatc, as long as the stalk of the densdysillcy ovoid ovary ; stigma 2-lobed, nearly 

 sessile. (S. grisea, Willd.) — Saaiy river-banks; not rare. — Shrub 4°-10o 

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

 or elongating in frait, thus appearing sessile. 



7. S. petiol^ris, Smith. (Pbtioi/ED Willow.) Leaves lanceolate, 

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

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

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

 stigma 2-cleft. (S. rosmarinifolia, and S. fuscJita, Purshf) — 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 tap, appearing like a single stamen. 



8. S. pCRpfjEBA, L. (PcRPLE WiLLOw.) Leaves oblanceolate, pointed, 

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

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

 bertiana, Purs/i.) — Low grounds. Recognized 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.) 



•*- •*- Filaments separate. 



9. S. VIMINA.LIS, L. (Basket Osiee.) Leaves linear-lanceolate, very long 

 and taper-pointed, entire or obscurely crenate, 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- 

 iana, 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.) 



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

 leaves in May or June : imier 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, with occasionally a 

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



10. S. cordata, Muhl. (Hsaht-leaved Willow.) Leaves lanceolate 

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

 smooth, paler beneath ; stipules kidney-shaped or ovate, toothed, often 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 base, cylindri- 

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

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

 lowest are somewhat elongated. (S. rigida, MuAl. S. Torreyiina, Barratt, 

 which has leaves of a 4eeper green beneath, appears to belong here.) — Var. 

 MTBico^DES has naiTowcr leaves, neither heart-shaped nor truncate at the base.
