municated by Warnstorf bearing the label, Hunker Creek, Yukon, 

 J. Macoun, '02. From the cuspidata jjroup the following are to be 

 noted: S. monocladum (v. Klinggr.) Warnst., S. Triniiensc C. Miill. 

 (known from Florida), S. fallax v. Klinggr., S. obtusum Warnst., S. 

 Balticum Russ., S. Schultzii Warnst., S. Jn/pnoides (A. Braun.) Bruch, 

 S. annulaium Lindb. fils; from the acutifolia group S. subtile (Russ.) 

 Warnst.; from the subsecunda group S. crassicladum Warnst., S. 

 turgidulum Warnst. Furthermore several sj)ecies of southern United 

 States range occurring as far north as New Jersey, mostly members 

 of the cymbifolia and subsecunda groups, may be sought in the coast- 

 region of Connecticut and Rhode Island. The specific value of most 

 of the latter segregates can hardly be regarded as determined without 

 more extensive collections. 



With reference to the record of localities from which specimens 

 were not seen Mr. J. F. Collins has very kindly examined the local 

 list and the — signs in the above list are to be accredited to him.^ —
