amenfs from ''Lake AVinnipe":, RichardsonJ' These specimens al- 

 though broiiiiht together from widely sundered stations, are rightly 

 mated even to the mature leaves, and show that the character of 

 the species was clearly understood ; they represent S. halmviifera, 

 Barratt, so completely in rtower, fruit and ioliage that there can be 

 no room for doubt as to what Dr. Barratt regarded as the type of his 

 species; and furthermore there is just as little uncertainty that ,S'. 

 injrifolia. Anders, is a recent name for the same plant. 



It is to be regretted that after so clearly indicating a distinct spe- 

 cies Dr. Barratt — in his desire. 1 imagine, to dispose in some way of 

 all the material placed in his hands — should have followi^l liis type 

 specimens with leaves only of S dl.Hcolor from ''Cumberland Houses 

 DrummoiuV' as ''54 var. intermedia''^ \ and leaves only of S. petiolaris 

 as "55 var. auguMifolia.'" But it is a rule that the in<-luding under 

 varieties what belongs to other species does not aH'ect the validity of 

 the species itself, and it should be borne in mind that while the type 

 specimens present a complete and unmixed series of tlow^ers. fruit 

 and leaves, the varieties so-called are shown l)y haveH only. That ,S'. 

 hahnniifera must have been represented by e([uivalent specimens in 

 the Hookerian herbarium goes with the saying, otherwise the reduc- 

 tion to (S'. cordafa in the Flora Boreali- Americana becomes ahsoluteh/ 

 inexplicable. Yet Andersson in his SoUcch Boreal i-AniericanfC^ p. 20, 

 remarks, ^'-Quantum, e speciminib/fs in herl). Hook, judicare jiossuin aS'. 

 balsamifera, cujus ramus foliis tectus tantum adest, ad S. arnfifoUum, 

 W., pertinet." And he then goes on to describe the leaves as about 

 4 inches long, }j an inch wide, sharply serrate, etc. Now there is 

 only one ^vcli .■^jKriinrn in the Kew herl)arium and that is like No. 55 

 above mentioned ; leaves only of N. jxtiiJaris and marked "B''; the 

 rest are all (for there is no e([uivalent of No. 54 in the Kew set) des- 

 ignated as the tyj)icalibrms of S. bahamifera and on the sheet is 

 written "N, cordafa. fide xVndersson, 1857." The leaves vary from an 

 inch to 1^ inches in width and are very similar to forms collected by 

 the Rev. James Fowler in New Brunswick. 



A friend, whose oj)inion is entitled to the utmost consideration, 

 has suggested that the Kew specimens were i)robabiy returned before 

 Andersson recognized in the collections of Bourgeau his (S*. pyrifolid 

 and that Barratt's No. 53 was overlooked or forgotten. Still in this 

 view of the case it is strange that we have a description in detail of 

 the leaves of S. petiolaris in the Kew herb., and finally a reduction of 

 S. balsamifera to S. discolor (in DC. Prod.) and never a word regard-
