Key to the Varieties 



1. Inflorescence simple, or if compound the ratio of secondary pedicels to primary pedi- 

 cels less than 0.3, usually no more than one secondary pedicel on any one primary 

 pedicel. var. acuminata. 



1. Inflorescence compound, the ratio of secondary pedicels to primary pedicels always 

 greater than 0.3, usually two or more secondary pedicels on some of the primary 

 pedicels. var. carolinae.

This taxon has a much more northern distribution than var. carolinae. It 

 ranges from southern Canada, through New England States, and into the north- 

 ern Midwestern States (Fig. 1). It is easily separated from the more southern 

 variety by the general lack of secondary pedicels in the inflorescence. In speci- 

 mens where secondary pedicels do occur, the ratio is always less than 0.3 and 

 rarely is there more than one secondary pedicel to a primary one. 



Type. Iu the original description no type was designated and no specimens 

 listed. Boreal America was mentioned as the type locality.
