Fox: SPECIES OF CYPRIPEDIUM. 441 



with long silky hairs, and is of a dull white color with delicate 

 wine tinted veins ramifying from the base of the labellum for- 

 ward. The staminodium is membranous, slightly carinate, 

 modelled, and ovate lanceolate in form. The fertile stamens 

 are closely attached to the column. The stigma is somewhat 

 quadrangular, slightly roughened and not indented. 



Cypripedium candidum Muhl. is often found in bloom in May 

 and June, in bogs and frequently on higher ground. Accord- 

 ing to Meehan, C. candidum is the "only one at home on the 

 open prairies. "^^1 



This species has been found "on the driest kind of a rocky 

 hill "^02 and. is also found in "open boggy places "i03 in the 

 state of Nebraska. By reason of the data at hand regarding 

 its presence in the "sub-humid " region and its ability to exist 

 under very different conditions of moisture the conclusion may 

 easily be drawn that it is not strictly a bog plant. 



C. candidum ranges from New York and Pennsylvania west- 

 ward to Nebraska, and from Canada to Illinois. 



It was first found in Pennsylvania^^-* although other author- 

 ities date the discovery of this species^"'' from 1826.io6 The 

 name of the " Small White Lady's Slipper" or "White Frau- 

 enschuh" is frequently given this form which seems to be 

 closely related to Cypripedium reginae Walt, in general appear- 

 ance. In 1876, Burgess^"''' reported the discovery of two forms 

 of C. candidum Muhl. the larger of which seemed to be allied 

 to C, reginae. This kinship can best be determined by exam- 

 ination of the ovules and by a study of the embryological de- 

 velopment. The floral conformation was studied and fifteen 

 organs made out by Asa Gray in 1886.1°^
