148 Bog-Trotting' for Orchids 



therefore surprised to find the sepals and side petals 

 yellow. 



Albinos of this species have been collected in this 

 district for four seasons. A colony, found near the 

 schoolhouse, produced six white blossoms. The chil- 

 dren, calling them faded Pink Moccasins, believed them 

 to have lost their color after maturing. It appears 

 from its persistence that the variety is permanent, and 

 not the freak of a season. The abnormal anther may 

 be present in all albinos. If so, it is evident that evo- 

 lution is taking place in the Pink Moccasin- Flower 

 through the suppression of one anther in genus Cypri- 

 pedium, which possesses two, while all other genera of 

 the family have but one anther. 



The colony of the Showy Lady's Slipper in Rattle- 

 snake Swamp, producing forty-two blossoms in 1899, 

 unfolded but fifteen flowers this season. For reasons 

 unknown to me, it was not a good year for Cypri- 

 pediums.
