12. CYPRIPEDIUM, LADY'S SLIPPER, MOCCASIN FLOWER. 



(Greek name for Venus, joined to that for a slipper or buskin.) Among 

 the most ornamental and curious of our wild flowers, blooming in 

 spring and early summer. Rootstocks very short and knotty, produc- 

 ing long and coarse fibrous roots. Many tropical species and hybrids 

 are in cultivation. (Lessons, Fig. 284.) 



* The three sepals separate ; stem leafy, one-flowered. 



C. arietinum, R.Br. RAM'S-HEAD L. The smallest species, with 

 slender stem 6'-10' high, oblong lanceolate leaves, and a dingy, purplish, 

 drooping flower, the sac conical and in some positions resembling a ram's 

 head, one sepal lance-ovate, the two others and the two petals linear. 

 Cold woods and swamps, Me. to Minn. 



* * Two of the sepals united by their edges into one under the sac or 

 slipper, but their very tips sometimes separate. 



-*- Stem l-2high, leafy to the l-3-flower<>d summit; leaves lance-oblong 

 or ovate, with many somewhat plaited nerves, more or less pubescent; 

 sac or slipper horizontal, much inflated, open by a rather large round 

 orifice.

 the sac.

 slightly pubescent ; sac like that of the next, but white-purple inside ; 

 sepals ovate-lanceolate. Bogs (rare), N. Y., W. and S. 



C. parvifl6rum, Salisb. SMALLER YELLOW L. Like the next, and 

 in similar situations, but stems and leaves generally smaller, and flower 

 ' about half the size, somewhat fragrant, the sac broader than high, deep 

 yellow, and the lance-ovate sepals browner.
