juDgit, ut etiam Asa Gray aliique," In the Prodromus, Andersson treats 

 S, priiioides in the same manner as S. eriocepJiala, that is as a var. ? pri- 

 noides of S. discolor, and remarks : " Obit praecipue memorabils utpote quae, 

 regiones magis septentrionales xVmericae orientalis praecipue inhabitans,

discolor there seem 



rather distinct varieties: one with " ramuUs foUisque ab initio glabris vel 

 tantum novellis pubescentia grisea fulvaque plusminusve densa cito evanes- 

 cente obtcctis "; the second with " ramuHs novellis dense tomentosis etiam

typical S. discolor. There may 



be a forma glaberrima of it to which certain forms from the northeast ought 

 to be referred. To the typical variety apparently belongs as a form with 

 narrower leaves and with a somewhat longer style S. prinoides sensu stricto. 

 The correct name for it, as already stated, seems to be S. discolor f . rigidior

The second variety with tomentose branchlets is the same as S. erio- 

 cephala Mich, and as var. eriocephala of most authors. The oldest name 

 that has to be used seems to be latifolia of Andersson, therefore the synon- 

 ymy may be indicated as follows: S. discolor var. latifolia Andersson in
