58 FAMILIAR FLOWERS OF FIELD AND GARDEN. 



Cypripedium parviflorum. 



The plant flowers in 

 early June. The name 

 Cypripedium in English 

 Avould be Venus's slip- 

 per. 



Yellow The small- 



Lady's Slipper. 



Cypripedium ■' 



panifloriim. lady's slip- 

 per, sister to the flower 

 just described, is found 

 in similar situations 

 where the ground is 

 moist, and has the ad- 

 dition of a slight per- 

 fume. The sac is small, 

 and is a deep-toned yel- 

 low ; the sepals are a 

 sienna brown. Another 

 larger yellow variety (<7. 

 puhescens), one of our 

 commonest orchids, has a 

 lighter-colored sac, and 

 is without perfume; but 

 I consider the smaller 

 variety more beautiful. 

 The time of flowering 

 for both is early summer.
