 Anders. 1. c. IGO, lig. 1)1* (not good). 



Var. Watsoni, 15ebb. Difl'usely branched, the short and divaricate yellowish- 

 green or grayish branches very smooth and polished : leaves smaller, oblong, short- 

 acuminate, 1 to 2 inches long, serr\date or nearly entire : anuuits 1 inch or less in

From the Nortlicni .States to tlie .\r(:tie Coast ; frenueiit tlirou;,'h Nevada and Ulali, in Colo- 

 rado and iiorlliward, aiiiian-nlly rare in CaHlornia. Collcctud liy lUihimdr in the Voscnnte N'alli'y, 

 and at Yreka by Urccuc • the variety ]l'atsuni, jieculiar in lialiit, near Carson City {ll'dtson), and 

 in Sierra County, Lcnnnoii : the vaiiety MiicLcir.iana (easily mistaken lor a form of .b'. lasiandra) 

 from Lake County (.hulcrson) and far northward ; certainly not a hybrid between -S'. cordata and 

 S. roslrata as conjectured by Andersson. 



8. S. lasiolepis, Benth. Leaves oblanceolate or rarely oblong-oblanceolate, 

 obliquely acute or acuminate, 4 to 6 inches long, \ to 1 inch wide, the lower spatu- 

 late, obtuse, more or less pubescent especially at lirst, at length glaucous and ferru- 

 ginous beneath ami coriaceous in texture, the margin unequally subserrate ; stipides 

 mostly wanting: aments sessile or scarcely peduncled with a few deciduous bracts 

 at base, H to 3 inches long, erect or somewhat llexuose, cylindrical, densely llow- 

 ered ; scales roumlish, dark, densely clothed with crisp white hairs : stamens yel- 

 low, 3 times the length of the scale ; filaments .slightly united at base : capsules 

 acute, smooth, dark green, shortly jiedicelled : styles medium sized ; stigmas short, 

 erect. — PI. Ilartw. 3.35; Amlers. DC. Drodr. xv>. 2G4. 



Var. Bigelovii, P.ebb. Leaves obovate or cuneate-oblong, obtuse, entire (at 

 least the earliest), grayish silky-pubescent beneath : aments on short and villous 

 often somewhat leafy peduncles : pedicel about the length of the villous scale. — 

 S. Biqeluvii/Vow. \n Pacif. P. licp. iv. 13'J ; Anders. Sal. Monogr. 103, fig. 94,

Var. (1) fallax, Pebb. Leaves lanceolate-obh»ng, abruptly contracted or even

Throughout tlie .State, from San Diego to Yreka, and in tlie Siena Nevada, tlie commonest of 

 CaHfornian willows and exceedingly variable, fn tlie neighborliood of San iMancisco and .south- 

 ward it attains under favorable conditions tlie lieight of -10 to (50 feet, but iiovthwaid and in tlie 

 mountains at 4,0(lO feet elevation is reiluced to a bush, less than 10 feet liigli, branching near the 

 ground. IJark smooth, grayish-brown, scarcely fissured even on old trees. Aments apjiearing 

 before the leaves, or southward, near i.os Angeles, etc., in the axils of the persistent leaves of tho 

 jnevious season. S. Ihiiiiiciji, IJcnth. (.V. /itnui/is, var. (0 H<(rturi/i, Anders. 1. c. '2'M\), is clearly 

 founded on this serotinous state. I'lofessor Andersson was ajiiiaicnlly deceived by the remarkable 

 resemblance which the leaves of tliis si)ecies bear to ,S'. huyailis when he asserts (1. c.) that he saw 

 S. humilis "in Calil'ornia, very common "
