22 Rhodora [January 



Anders, as to S. serlrca. That species, however, has a finer pubes- 

 cence, paler scales, smaller aments and capsules, and small entire 

 revolute leaves without stij)ules. 



Differing, then, in essentially all characters from the more southern 

 Salix scricca with which it has been confused and the arctic-alpine S. 

 an/ijrocarpa to which it is as closely related, the shrub of the Penobscot 

 Valley seems worthy s])ecific separation from those species, and it is 

 here proposed as 



Salix coactilis, sp. n. I^'rutex altus, ramis crassis subquadratis 

 fusco-viridibus vel atris junioribus griseis puberulis; foliis oblongis 

 vel lanceolato-ovatis longc acumiiuitis junioribus subtus dense pubes- 

 centibus, pilis rufo-albidis fulgidis coactilibus, demum subtus velutinis 

 supra viridibus 6-12 cm. longis 2-3.5 cm. latis remote et argute glan- 

 duloso-dentatis, petiolis gracilibus 1-1.5 cm. longis griseo- velutinis; 

 stipulis semi-ovatis glanduloso-serratis 4-5 mm. longis ]>ersistentibus; 

 amentis foliato-})edunculatis cylindricis 2-3.5 cm. longis, fructiferis 

 4-5.5 cm. longis 7 mm. crassis; scpiamis oblongis vel obovatis ajiice 

 obtusis vel rotundatis fuscis vel nigrescentibus longe ])ilosis, pilis lami- 

 nam aequantibus; capsulis coiiico-subulatis 5 mm. lf)ngis albido- 

 villosis pedicellatis, jx-dicello nectarium quintuj)lo superante; stylo 

 distincto 0.5 mm. longo, stigmatibus brevibus bilobatis. 



Large shrub with coarse stiff branches; branchlets somewhat quad- 

 rangular, dark green or blackish, the youngest gray and puberulent:
