Var. pubescens (Larger Lady's Slipper) differs in being a larger 

 flower with stem about the same height, i to 2 feet. Lip, a green- 

 ish yellow, striped with purple, Sepals, lance - shaped, long, 

 twisted, lip much swollen. Leaves, oval, pointed, quite broad,

Twayblade 



Listera con-vattarwides rises from a cluster of fibrous roots 4 to 

 10 inches high, with 2 broad, roundish leaves near the center of 

 the scape. 1 or 2 small scales near the base. Flowers, greenish 

 yellow, on thread-like pedicels attended by a tiny bract, in loose 

 racemes, 3 to 12 in a spike. Lip much longer than the sepals and 

 petals, double-lobed at the apex, generally with 2 sharp, ear-like 

 projections at the base. Summer. 



From Vermont southward to North Carolina; found in 

 the Southern States among the mountains. 



Southern Twayblade 



L. austrklis bears very small greenish-yellow flowers with pur- 

 ple stripes. The narrow lip is h inch long, slit nearly its entire 

 length. Leaves, ovate, sessile, a pair attached just above the 

 middle of the scape. Rarely a third leaf occurs near the raceme 

 of flowers. Scape, 4 to 10 inches high. 



In wet woods or bogs from New York to Florida. 



Whorled Pogonia 



Pogbnia <verticiUkta. — Family, Orchis. Color of sepals a dark

Smaller Whorled Pogonia 



P. af finis. — Color, greenish yellow. Flowers, generally in pairs, 

 on scapes, 5 or 6 inches high, which bear a whorl of 5 leaves at
