inches long" (m., f.) from typical S. myrtilHfolia, and Ball, too, in his 

 MS -list refers curtiflora as a synonym to this species. 



In 1867 and 1868, Andersson, as already mentioned, changed the name 

 curtiflora to pseudocordata referring to it also specimens of Bourgeau's 

 ("ad fl. Saskatchewan, prope Fort Pitt"), of which there are male and 

 female fragments in Herb. BeroL, and Burke's ("Jaspers house") which 

 I have not yet seen. The specunen from near Fort Pitt represents noth- 

 ing but typical S. myrtilHfolia. Besides it he adds "in Rocky Mountains 

 (Drummond)." This last specimen is in the Gray Herbarium and 

 represents No. 659 of Drunimond's. According to the label it came with 

 No. 665 which I have seen in Herb. N. Y. Those two numbers consist 

 of male and female pieces with young flowers and leaves, and there is 

 hardly a good character to separate them from S. myrtilHfolia except that 

 the bracts (at least of the male flowers) are mostly "crispo-albo-villosae" 

 in No. 665 while they are almost glabrous in No. 659, and agree in every 

 respect with those of tj^jical S. viyrtillifolia. Of course the size and shape 

 of the leaves cannot even be guessed. 



There is good reason to doubt whetlier Andersson's subspecies or variety 

 -pseudocordata has anything to do with S. pseudocordata of Ball in his MS.- 

 list. Eydbcrg, Fl. Rocky Mts. 194 (1917) has used the names S. curti- 

 flora (with the synonym pseudocordata) and S. pseudomyrsinites appar-

can only hope that Ball will be able to elucidate these critical forms which 

 have been named and renamed by Andersson, as Fernald, said, but also 

 by later authors "in a perplexing fashion." 



Fernald, in Rhodora xvi. 172 (1914), proposed a S. myrtilHfolia var. 

 hrachypoda from Ne^vfoundland, and Ball, as already mentioned, keeps a 

 S. myrtilHfolia var. lingulata in Herb. W. and his MS.-lists {S. myrsinites

 have seen specimens determined by Ball from the Northwest Territories 

 (Fort Providence, Fort Resolution and Hudson Bay) and Saskatchewan, 

 without exact locality, collected by Bourgeau in 1859. The var. lingu- 

 lata does not seem to represent anything but a vigorous form of the type. 



Of this I have been able to examine specimens from Alaska (Copper 

 River Region, Yukon Valley), the Yukon Territory (Dawson, Lake 

 Bennett), the Northwest Territories (Fort Franklin, Yahami Mts., Tazin 

 River, Fort Providence, Hudson Bay, Churchill) Alberta, Saskatchewan, 

 Ontario (Lake of Woods), Quebec and Labrador; it probably also occurs in 

 the northern parts of the Rocky Mountains in the United States, where it 

 seems to be replaced by the following species.
