SALICACEJE. (WILLOW FAMILY.) 427 
black; stigmas nearly sessile. (S. Lamberticina, Pursh.) — Introduc¬ 
ed from Europe ; 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. 
■*- Filaments separate. 
9. S. ViminaliS, L. (Basket Osier.) Leaves linear-lance¬ 
olate, 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 elongated ; stigmas linear, 
mostly entire. — Wet meadows. Introduced from Europe, and con¬ 
sidered the best species for basket-work. Leaves S 7 -6'long, of a 
beautiful lustre beneath.— S. Smithiana, Willd ., another species of 
this section, differing principally in the somewhat broader leaves, has 
also been introduced, and is occasionally met with. 
§ 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 separating from the cartilaginous exterior, some¬ 
times 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. (Heart-leaved Willow.) Leaves 
lanceolate or ovate-lanceolate, truncate or heart-shaped at base , taper- 
pointed, sharply toothed , smooth, paler beneath; stipules kidney-shap¬ 
ed 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, cylindrical, the fertile 
elongating in fruit; ovary lanceolate, tapering to the summit. — Var. 
1. rigid a, has the leaves large and rigid, with coarser teeth, of which 
the lowest are somewhat elongated. (S. rigida, Muhl.) S. Torreya- 
na, Barratt, which has leaves of a deeper green beneath, appears to 
belong here. — Var. 2. myricoIdes, has narrower leaves, neither 
heart-shaped nor truncate at the base. (S. myricoides, Muhl.) — Inun¬ 
dated banks of rivers and low meadows. — Shrub 2° - 6° high : the 
var. 1. larger, or a small tree (P-15P high, with leaves 4 7 -t> 7 long. 
Fruiting catkins 2'-3' in length. 
11. S. angmstata, Pursh. (Narrow-leaved Willow.) 
Leaves lanceolate, acute, long and tapering to the base, slightly toothed, 
smooth and scarcely glaucous beneath ; stipules half-heart-shaped ; 
catkins large, appearing before the leaves ; ovary tapering into a long 
style -New York to Penn, and west to Wisconsin. — Catkins re¬ 
sembling No. 4 in size and aspect; but the ovaries are quite smooth 
and very white. 
§ 3. Catkins lateral, with a few leafy bracts at the base, appearing icith 
the leaves in May or June : ovary stalked, silky : stamens 2 : scales 
persistent.
