336 SALTCINE^E. ( WILLOW FAMILY.) 



at first wrapped in the leaves of the short peduncle : scales obovate-roundish, 

 apex black, villous with white hairs : capsules conic-rostrate glabrous, green 

 or reddish, short-pedicelled : style medium ; stigmas thick, entire, erect. 



Var. pseudo-myrsinites. Small shrub 1 to 3 feet high, divaricately 

 branched : leaves l inches long, inch wide, short petioled, membranaceous : 

 prominently nerved aments leafy-bracted, l inches long. 



Var. pseudo-COrdata, Anders. By no means a tall shrub, branches 

 upright: leaves oval-oblong, l. inches long, inch wide, scarcely narrower 

 below the middle, roundish at base, apex produced, rather acute, margin 

 minutely serrulate : aments about an inch long. 



Rocky Mountains of Colorado and Montana (valley of Nevada Creek, 

 Canby), and northward to the Saskatchewan and Mackenzie Rivers. 



6. S. irrorata, Anders. Leaves linear-lanceolate, 3 to 4 inches long, ^ inch 

 or less wide, very smooth, somewhat coriaceous, bright green and shining above 

 except the yellowish midrib, paler or often intensely glaucous beneath, remotely 

 undulate-serrate; petioles inch long ; buds large, roundish ; stipules evanescent : 

 aments all appearing before the leaves, an inch long, crowded on the branches, 

 sessile, scarcely bracted, very densely flowered ; males oblong, golden-yellow ; 

 females erect or spreading, at length 1 to l inches long : scales dark, obtuse, 

 villous : capsules ovate-conical, smooth, green, scarcely pedicelled : style 

 medium ; stigmas very short, entire or bifid. Shrub 6 to 8 feet high, with 

 upright branches. One-year-old twigs often covered with a beautiful glaucous 

 bloom, which is easily rubbed off; not present on vigorous young shoots. 

 Mountains near Golden, Greene; Manitou, Brandegee, Jones; Empire City, 

 Engelmann. Only the very young leaves (an inch long) accompanying the 

 flowers and fruit of Fendler's No. 812 were known to Professor Andersson. 



7. S. monticola, Bebb. Leaves oblong-lanceolate, the earliest obovate, 

 acute, 3 to 6 inches long, 1 to If inches wide, glabrous, rigid and glaucous 

 beneath or thin and pale beneath, unevenly crenate or serrulate ; stipules large, 

 semicordate, acute ; buds large, ovate and beaked at the tip : aments thick, densely 

 flowered, sessile ; males closely so ; females with a few broad bracts at base, 

 when in flower about an inch long, lengthening in fruit to 1^ or 2 inches : scales 

 oval, obtuse, clothed wtih long yellowish-white silky hairs: capsules ovate- 

 conical, glabrous, sessile or nearly so : style elongated ; stigmas erect, bifid 

 or entire. Marshy places along streams, mountains of Colorado : Golden, 

 Greene; Georgetown, Patterson; Empire City, Engelmann. Also collected in 

 fragmentary specimens, mostly old fruiting aments, by Hall and many other 

 subsequent explorers: probably common. A densely cespitose shrub, 8 to 12 

 feet high, stem 1 to 2 inches in diameter. The broad, irregularly-toothed 

 leaves (especially when rigid and glaucous beneath) bear a remarkable resem- 

 blance to those of S. discolor ; a resemblance heightened by the conspicuous 

 stipules on vigorous shoots ; but the aments are very different. Allied to the 

 foregoing and more nearly representing the European S. daphnoides, S. irro- 

 rata being the equivalent as it were of S. acutifolia. 



* * Capsules tomentose (rarely glabrate in 12 and 13). 

 t- Pedicels slender, style obsolete or none. 



8. S. flavescens, Nutt. Leaves obovate or oblanceolate, acute or the 

 lower obtuse, wedge-shaped at base, 2 to 3 inches long, 1 to 1 inches wide,
