Willow Family 101 



and shining above, more or less glaucous beneath, 8-12 cm. 

 long, glabrous ; petioles about 1 cm. long; puberulent above and 

 somewhat grooved ; staminate aments usually flexuose, 5-7.5 cm. 

 long; bracts more or less elliptic, woolly at base, glabrous and 

 pallid towards the apex; stamens 5-6; filaments pubescent 

 below ; capsule conic from a thick base, acute, glabrous, on ped- 

 icels 3-4 times as long as the gland; stigma nearly or quite 

 sessile, emarginate. 



Frequent along all our streams, especially in the canyons. 



** Stamens 2, rarely 1. 



-*- Aments subsessile on leafless peduncles. 



4. S. lasiolepis Benth. Tree or large shrub, 4-8 m. high; 

 leaves oblong or somewhat broadest above the middle, obscurely 

 and irregularly serrulate, dull green above, more or less gray- 

 pubescent beneath, 12-20 mm. broad, 5-7 cm. long, on petioles 

 5-10 mm. long; aments appearing before the leaves, suberect; 

 the staminate 2-4 cm. long; stamens 2; pistillate 2.5 cm. long or 

 less ; capsule acute, smooth, short pedicelled ; styles rather short ; 

 stigmas erect. 



The most common willow, covering a considerable area along the Santa 

 Ana and San Gabriel Rivers toward the coast. 



-*--*- A ments terminating leafy branchlets. 



5. S. Parishiana Rowlee. Slender shrub, 1-3 m. high; young 

 twigs cinereous strigose; leaves linear-lanceolate, minutely and 

 remotely denticulate, 5-7 cm. long, 3 mm. wide, silky canescent 

 when young, glabrous and somewhat coriaceous when mature, 

 veins few but very prominent; stipules none; aments on long 

 leafy peduncles, 2-3 cm. long, the upper leaves of the branch 

 much surpassing the ament; flowers dense; scales white, densely 

 villous all over, oblong, acute ; filaments scanty hairy at the base ; 

 capsules densely villous, oblong, closely sessile; style distinct; 

 stigmas linear. 



Not uncommon around San Bernardino according to Parish. This and the 

 following species are very doubtful and might, with apparently good reasons, 

 be put into a single species, but the author has preferred to retain them 

 until our California forms of this difficult group are better known. 



6. S. macrostachya Nutt. Shrub or small tree, 1-6 m. high, 

 often in dense thickets ; bark light brown, cinereous, young 

 branches villous; leaves 5 cm. long, 1 cm. wide, sessile or nearly
