276 BAY WILLOW 



J# Leaves not involute, and buds with 

 only one scale ; dwarf shoots not 

 thorn-like. 



-J- Petiole glandular. Leaves polished 

 and large. Erect shrub. Shoots 

 neither violet nor covered with waxy 

 bloom. 



Salix pentandra, L. Bay Willow (Fig. 105). Glabrous 

 shrubby tree. Leaves broad elliptic-ovate to ovate- or 

 obovate-lanceolate ; or oblong or broadly lanceolate, 6 10 

 x 3 5 cm. (3 15 x 1 5 cm.), viscid when young, then 

 sub-coriaceous, quite glabrous, and very brilliant green, 

 paler and reticulate beneath. Suddenly acuminate. Densely 

 and somewhat obtusely glandular-serrate. Fragrant, with 

 a faint Laurel-like odour. At most three times as long as 

 broad, generally less. Petioles short, about 1 mm., with 

 black or green glands, two of which represent stipules, 

 and are ovate or oblong-lanceolate, erect and gland-toothed 

 and caducous; but the stipules may be obsolete. The 

 leaves are thicker and more glabrous and shining than is 

 usual in Willows, and these characters, their shape and 

 the petiolar glands combine to make them resemble the 

 leaves of a Primus. Midrib yellowish. There are no 

 stomata above. Autumn leaves yellow. 



Venation like that of S. alba and S. fragilis, but the 

 secondaries loop within the margin, and the tertiaries are 

 long and more prominent as cross-ties. 



[The leaf-insertion is extended and narrow, crescentic, 

 a peculiarity useful, in conjunction with the buds, which 

 show several scales visible even in summer, in distinguish- 

 ing the somewhat similar leaves of Primus. See p. 274. 



When the petioles of S. daphnoides and S. fragilis 

 develope glands, as sometimes happens, they will come 

 here. See pp. 246 and 278.]
