408 ORCHIS FAMILY. 



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

 very Irat'y ; kaves lanceolate ; spike dense, often long ; flowers greenish, 

 the lanceolate lip like the t)ther petals, spreading, entire, about the length 

 of the incurved spur ; glands orbicular. 



++++++ nowers 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. Kng., W. and 8. 



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

 G'-12' hiul), 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- ■*- 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 0. 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 gi'eenish-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. Hodkeri, Torr. Smaller in all parts ; flowers in June ; the orbicular 

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

 bearing fewer yellowi.sh-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 lower end strongly projecting forwards. 

 These are our handsomest ivikl Orchises; all grow in bugs or low 

 grounds; stems leafy, 1^-4° high. 



4- Floivers bright orange-yellow, in late sntnmer ; glands orbicular, pro- 

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

 ovary and jwd long, tapering to the summit. 



H. cristita, 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. .r., s. 



H. ciliaris, R. Br. Yellow Fringep O. Taller ; \h°-^° 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 \Y. 



■*- -t- Flowers bright ichite, in summer; the lip fringe-margined but not 



chft. 



H. blepharigl6ttis, Torr. Wmtte Fhinoed 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.
