The larger 3-ellow ]\Ioccasin Flower. 



more recently Fritz Kranzelin and Oakes Ames report at least 

 eighty-three Cypripcdiuins and several hundred natural hy- 

 brids, the latter chiefly among the exotics from the Tropics. 

 There are also several interesting hybrids produced by crosses 

 between the exotics with the terrestrial species. The collectors, 

 so far, have not discovered any species of Cypripcdiuin in 

 Africa or Australia, although those regions produce a pro- 

 fusion of other species of the Orchis Family.
