 obovate, almost entire; lip spreading, only ^' wide, cut into denser fringe. 



H. peramOBna. From Penn. W. & S. along and near the mountains : 

 flowers of size intermediate between the two preceding, the broad wedge-shaped 

 lobes of the lip moderately cut-toothed, but not fringed.

almost facing each other : spike long and loose. 



H. leucophsea. From Ohio W. & S. : 2° -4° high; leaves lance-oblong ;

H. blephariglottis, White Fringed 0. Peat-bogs N. : like the next, 

 but rather smaller, 1° high, the fringe of the lance-oblong lip hardly equal to 

 the width of its body. 



* * * * Floioers bright orange-yellow, in late summer: glands orbicular, projecting 



on the beak-pointed bases of the very diverging anther-cells : ovary and pod 



long, tapering to the summit. 



H. Cili^ris, Yellowt Fringed 0. Sandy bogs: \^°-2° high; leaves 



oblong or lanceolate ; spike short, of many crowded very showy flowers ; petals

 with a narrow lacerate fringe. 



§ 2. Yellow, green, or white species, with lip entire, at least not fringed. 



* Stem leafy: leaves oblong or lanceolate : fowers small: anther-cells nearly parallel. 

 H. Integra. Pine barrens from New Jersey S. : resembles H. cristata, 



having small bright orange-yellow flowers, but the lip is ovate and entire or

 lower leaves obovate, upper reduced to bracts of the short spike, which are much 

 longer than the green flowers; lip truncate and 2 - 3-toothed at the tip, very 

 much longer than the sac-shaped spur. 



H. hyperbdrea. Cold low woods and bogs N. : 6'- 2° liigh, very leafy; 

 leaves lanceolate ; spike dense, often long ; flowers greenish, the lanceolate lip 

 like the other petals, spreading, entire, about the length of the incurved spur. 



H. dilatata. Resembles the last, grows in same places, but commonly more 

 slender and with linear leaves ; flowers white, less wide, open, the lanceolate 

 lip with a rhombic-dilated base ; glands strap-shaped. 



H. nivea. Sandy bogs, from Delaware S. : I°-2° high, all the upper 

 leaves bract-like; flowers white, in a loose cylindrical spike, very small, ditterent 

 from all the rest in having the (white) ovary without a twist, and the linear- 

 oblong entire lip with its long thread-like spur therefore looking inwards. 



* * Stem a naked scape: the leaves only 2 at the ground: flowers pretty large in 



a loose spike: anther-cells widely diverging at their tapering or beak-like 

 projecting base. 



H. Orbicvd^ta, Great Green 0. Evergreen woods and hillsides N. : a
