CYPRIPEDIUM L. 



Considerable interest attaches to the group of yellow lady's- 

 slippers on account of Dn P. A. Rydberg's article^ which brings 

 up the question as to whether there are three species of yellow- 

 flowered Cypripediums instead of two, as commonly given in recent 

 manuals. An examination of fresh specimens during two seasons 

 since, leads me to believe, "we do have three species of yellow 

 lady's-slippers, one large and one small-flowered, both with ver- 

 tically flattened lip, and a third . . . one with laterally flattened 

 lip." I must, however, differ somewhat from the accepted treat- 

 ment of their nomenclature, ■

Differs from C. pitbcsccns, apparently in size only, and is usu- 

 ally found in more swampy situations than C. pubescens. Conser- 

 vative treatment may reduce this to a variety o{ pubescens.
