In 1907 Fernald stated that S. fitscescens "hitherto known only from 

 northern and western Alaska and the adjacent coast of Siberia, is abun- 

 dant in bogs on the serpentine tableland of Mt. Albert" on the Gaspe 

 Peninsula. According to my own observationvS the eastern specimens 

 all belong to var, hebecarpa described by Fernald, and it may even be that 

 this variety can be raised to the rank of a species. It chiefly diflFers from 

 typical S. fuscescens by foliis saepissime apice paullo acutiusculis vel dis- 

 tincte acutis, capsulis pedicello brevi ut videtur fere semper plloso vix 

 ultra 1.5 mm, longo excluso vix ultra 6-7 mm. longis brevius rostratis basi 

 crassioribus, saepissime plusminusve vel omnino (praesertim basi) pilosis et 

 distinctius glaucescentibus. What Fernald regards as typical fuscescens 

 is in my opinion, only a glabrescent form of var. hebecarpa of which the 

 pedicels never become wholly glabrous, and are always comparatively 

 shorter and thicker than those of Irne fuscescens , 



There is a female specimen collected by Trelease & Saunders under No. 

 S443 mixed with S, ovalifolia w^hich Coville refers to S, fuscescens. It has, 

 indeed, flowers very similar to those of this species but the ovaries are hairy 

 and borne on shorter and thicker pedicels. It looks to me like a hybrid, and 

 I do not think that it is a hairy form of S. fuscescens identical with the east- 

 ern var. hebecarpa. 



There remain to discuss several species w^hich I at present am unable to 

 refer to one of the sections with which I have dealt. 

 The first is
