 tioned by Andersson even as a synonym. One might be inclined to apply 

 this name to what we now call var. perrostrata if there was not the statement 

 that the leaves are rather larger than those of var. americana. Forms with 

 such large leaves apparently do not belong to S. Bebbiana but to S. discolor 

 or S. balsamifera. Only by a type specimen can the identity of the large-

Of these var. obovata, according to the author is "forma typica. ubique in 

 America septentrionah frequens." He distinguished two forms of it: f. 

 suhambigua and f. subrepens. The first is characterized by "foliis ovali- 

 obovatis, rigidissimis, margine remote serrulatis, subtus lucide tomentellis." 

 It was collected by Lyall " in Sumass-prairie." The second differs by 

 "foliis lingulato-lanceolatis basi longe attenuatis, breve acuminatis,^ IJ

 as uncertain, while I take var. obovata for a synonym of typical Bebbiana. 



A narrow leafed form of the type seems to be Andersson's var. lanceolata 

 of which in 1867 he says: "foliis elongatis supra medium parum dilatatis, 

 fere 2 poUices longis vix f poll, latis, utrinque pilis adpressis incano-hirtis; 

 amentis magis densifloris." He himself adds " foliis tantum angustioribus 

 a praecedente [var. obovata] recedunt." The diagnosis of 1868 is some- 

 what different, and it is impossible to decide the identity and the taxonomic 

 value of this variety without the type.
