should be looked for at other ponits in New England and New York. 

 Its occurrence with Betnia pumila, Salix Candida, Catex Schweinitziu 

 and other characteristic swamp plants of the Berkshire and Taconic 

 Mountain region, indicates that it may be sought with some confidence 

 in Jknnington County, Vermont, and with real assurance in Dutchess 

 and Columbia Counties, New York. In fact, the junction of these 

 two counties of New York with Litchfield County, Connecticut, is at 

 the base of Mount Riga, just north of the State Line swamp where 

 Salix serissima was first studied by the writer. Larch swamps to all 

 appearances the same extend westward from northern Litchfield 

 C'ounty nearly to the Hudson Valley, and are characterized ^ by Bciula 

 piimi/a, Sa/ix Candida, Valeriana syh'atica. Viburnum Opuliis, Cypri- 

 pcdiiini spcctahih\ Carex Sc/nvrinitzii, C. tetanica, C. terefiitscu/a, var. 

 ramosa, etc., all of which with the exception of Valeriana (abundant 

 only three miles west of Salisbury) are among the typical plants of 

 the Stockbridge or the Salisbury marshes ; while many of them occur 

 with Sa/ix serissima in the swamps of northern New Jersey, in the 

 famous Bergen Swamp of Genesee County, New York, or in the 

 marshes near Cayuga Lake. It will, then, be indeed surprising if 

 an exploration of similar tracts fails to reveal in eastern New York, 

 as in western xMassachusetts, northwestern Connecticut, northern 

 New Jersey, and northwestern New York, Sa/ix serissima as a com- 

 panion of these notable species. ■ ",

A Mosr noteworthy instance of the segregation of an old species 

 is to be found in the recent treatment of the common blue violet. 

 The polymorphous group of plants included in the last edition of the 

 Gray Manual under Vio/a pa/mata and its var. cucu//ata, it is now 

 proposed to divide up into at least thirty species.
