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-2 high, leafy to the l-3-ftowered 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. 



++ Sepals and linear wavy-twisted petals brownish, pointed, larger than 

 the sac. 



C. c^ndidum, Muhl. SMALL. WHITE L. Small, barely 1 high, 

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

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



C. parvifldrum, 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.
