l*->4 JOIKNAL OF THE ARNOLD ARBOllETUM (vol. a 



'J'he type of S. viyrtiUiJoUa of wliich I have before me a photograph 

 and fragments ex Herb. Kew was collected by Drunnnond "June 

 22nd, low situations, Rocky Mountains east side." Of Andersson's 

 subspecies >S. fseiidomyrsinites (1858) the type was found by Douglas 

 "on the grandrapid of Sascatchawan. " It is probably preserved in the 

 Ilookerian Herbarium, but I have only seen a co-tyi)e in Herb. Gray. 

 This specnnen is cited by Andersson, in 1867 and 1868, as the type of his 

 forma lingulata of the subspecies or variety 'pseudomyrftiniics, and Ball in 

 Herb. W. and in his MS.-list regards this form as S. myrtilUfoUa var. 

 lingulata (see below.). 



Andersson, however, in 1858, under S. pscudomyrsiriites mentioned an- 

 other specimen from the Rocky Mountains which is probably the same 

 as the type of what he (in 1867 and 1868) called var. cordafa of the sub- 

 species or variety pneiulo-imjrsimtcs. This variety cordaia has been in 

 the first place described from sterile specimens ("Folia attamen tantum 

 vidi") collected by Drummond which also should be looked for at Kew, 

 but Andersson had before him also a piece of Bourgeau's.* Unfortu- 

 nately he does not quote the localities where these spcchucns came from, 

 and I have only seen the material (luoted in the footnote which could 

 be regarded as the type of tJiis var. cordata. Ball is now using this name 



for a variety of what he (in Herb. C. and his MS.-list) calls S. pscudo- 

 cordata (see below). 



Andersson proi)osed still anotlier form, aequalis, of his subspecies or 

 variety S. psciidomysrinites. In 1867 he quotes as type a specimen col- 

 lected by Bourgeau "in campement forct brulo Rocky Mountains 15 

 Aug. 1858." I have not seen this type or any other specimen truly 

 representing the form Andersson had in mind. In 1909, Ball described 

 a S. pscudomyrsiniles var. eqnalis (!), and in Herb. W. and his MS.-list 

 he changes this name to S. pseudocordata aequalis. Ball's variety seems 

 to me to present a good species but I doubt whether it is really the same 

 as Andersson's form. 



Andersson's second subspecies S. curtifiora (1858) is founded on a 



specimen collected by Richardson at Fort Franklin on the Mackenzi 



River. There are two specimens of Richardson's in Herb N Y. of which 

 the one numbered "no. 69 lib. II. B. & T." (m., f., fr.) may be identical 

 with the real type (])robab!y preserved in Herb. Kew), but it does not 

 exactly fit Andersson's descrii)tion made in 1858 in whicli he states that the 

 pedicels are three times longer than the bracts and four times longer than 

 the gland; some flowers ho\\cver agree rather well with these indications, 

 and I am unable to distinguish this no. 69 or the second specimen ex- 

 Herb. BarratL (N. Y.) "Fort Franklin, low dei)ressed shrub 12 or 14

 Rocky Mts. and named by Andersson "*SaZi.i- (cordata) psrudormjrsuntrs". It apices with 

 the description of var, cordaia but the branchlets are pul)escenl and the leaves hardly more 

 than half an mch wide.
