408 ORCHIS FAMILY. 



H. hyperb6rea, R.Br. Cold low woods and bogs, N.; 6'-2 high, 

 very leafy ; leaves lanceolate ; strike dense, often long ; flowers greenish, 

 the lanceolate lip like the other petals, spreading, entire, about the length 

 of the incurved spur ; glands orbicular. 



++ -M. ++ Flowers green. 



H. vir^scens, Spreng. Stem 10'-20' high, with a conspicuously 

 bracted at length, long and loose spike of small flowers ; the lip oblong, 

 almost truncate at the apex, its base with a tooth on each side and a 

 nasal protuberance on the face ; spur slender, club-shaped. Wet places, 

 N. Eng., W. and S. 



H. bracteata, R.Br. Cold damp woods N. (S. in the mountains); 

 6'-12' high, with lower leaves obovate, upper reduced to bracts of the 

 short spike, which are much longer than the flowers ; lip truncate and 

 2-3-toothed at the tip, very much longer than the sac-shaped spur. 



-t- -t- 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. orbiculata, Torr. GREAT GREEN O. Rich, mostly evergreen 

 woods and hillsides N., and in the mountains S.; a striking plant; its 

 exactly orbicular leaves 4'-8' wide, bright green above and silvery be- 

 neath, lying flat on the ground ; scape l-2 high, bracted, bearing many 

 large greenish-white flowers in a loose raceme ; sepals roundish ; lip 

 narrowly spatulate-linear and drooping; spur 1|' long, curved, gradually 

 thickened towards the blunt tip ; flowers July. 



H. Ho6keri, Torr. Smaller in all parts ; flowers in June ; the orbicular 

 leaves only 3'-5' broad and flat on the ground ; scape naked, 6'-12' high, 

 bearing fewer yellowish-green flowers in a strict spike ; sepals lance- 

 ovate ; lip lanceolate and pointed, incurved, the other petals lance-awl- 

 shaped ; spur slender, acute, nearly 1' long. Swamps and damp woods, 

 N. A variety (var. oblongif61ia, Paine) has oblong leaves. 



* * Lip and often the other petals cut-fringed or cleft, shorter than the 

 long curving spur ; cells of the anther more or less diverging and tapering 

 below, the sticky gland at their lov:er end strongly projecting forwards. 

 These are our handsomest wild Orchises; all grow in bogs or low 

 grounds; stems leafy, l-4 high. 



H- Flowers bright orange-yellow, in late summer ; glands orbicular, pro- 

 jecting on the beak-pointed bases of the very diverging anther cells; 

 ovary and pod long, tapering to the summit. 



H. cristata, R.Br. Leaves narrow, and flowers small ; petals crenate, 

 and the ovate lip with a narrow lacerate fringe ; bracts nearly the length 

 of the crowded flowers ; incurved spur little longer than the lip. Bogs, 

 N. J., S. 



H. ciliaris, R, Br. YELLOW FRINGED O. Taller ; l-2 high ; leaves 

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

 much larger flowers ; petals cut- fringed at apex, the oblong body of the 

 lip (about half the length of the spur) narrower than the copious long 

 and fine fringe ; bracts shorter than the ovaries. N. Eng. , S. and W. 



- -i- Flowers bright white, in summer; the lip fringe-margined but not 



cleft. 



H. blepharigldttis, Torr. WHITE FRINGED 0. Like the last, but 

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

 the width of its body. There is a form with less fringed lip. Peat 

 bogs, N.
