508 OKCHIDACE^E. (ORCHIS FAMILY.) 



boidal-dilated base, entire, its base with the bases of the petals and sepals erect- 

 connivent, above spreading ; anther-cells almost parallel ; glands approximate, 

 large and strap-shaped, vertical, nearly as long as the pollen-mass and its short 

 flat stalk together ; stigma narrow ; a trowel-shaped conspicuous beak between 

 the bases of the anther-cells. Cold bogs, Conn, to N. Y., Mich., Minn., and 

 northward. 



* * Flowers greenish or white, 5- 15 in a loose spike, rather large for the size of 



the plant; scape or stem naked above, l-leaved at base (5 -9' high); spur 

 not longer than the lip ; anther-cells wholly adnate, arcuate and widely sep- 

 arated. 



8. H. obtusata, Richardson. Leaf obovate or spatulate-oblong ; upper 

 sepal very broad and rounded, the others and the petals lance-oblong ; lip en- 

 tire, linear or lanceolate, deflexed (3" long), about the length of the tapering 

 and curving spur. Cold peat bogs, Maine and N. New Eng. (Mt. Wachusett, 

 Mass.), to Minn, and northward. (Eu.) 



* # # Flowers white or greenish, numerous in a loose spike, on a naked scape, 2- 



leaved at base ; spur longer than the narrow entire lip ; anther-cells widely 

 diverging , their narrowed beak-like bases projecting forward ; stalk of the 

 pollen-mass laterally affixed to the back of the orbicular gland, the viscous 

 face of which looks obliquely inward. 



9. H. Ho6keri, Torr. Leaves orbicular, spreading (3 -4' broad); scape 

 mostly naked (^- 1 high), bearing 10-20 upright sessile yellowish-green flow- 

 ers in a strict spike ; sepals ovate-lanceolate ; lip lanceolate, pointed, incurved, 

 longer than the lance-awl-shaped petals ; spur slender, acute, about the length of 

 the ovary (nearly 1' long). Damp woods and borders of swamps, N. Scotia 

 to N. J.. west to Minn, and Iowa. Var. OBLONGIF6LIA, Paine, has oblong 

 leaves (3 - 5" by H - 2'). N. Y. and Can. 



10. H. orbiculata, Torr. Leaves very large (4-8' wide), orbicular, 

 spreading flat on the ground, shining 'above, silvery beneath ; scape bracted 

 (1 -2 high), bearing many spreading greenish-white flowers in a loose raceme,- 

 upper sepal orbicular, the lateral ovate ; lip narrowly linear and slightly spatu- 

 late, obtuse, drooping, nearly thrice the length of the oblong-lanceolate and 

 falcate obtuse petals ; spur curved, slender (about 1$' long), gradually thickened 

 toward the blunt apex, twice the length of the ovary ; anther-cells strongly pro- 

 jecting at the free beak-like base (the glands nearly J' apart). Rich woods 

 (especially coniferous), Newf. to Penn. and in the mountains to N. C., west to 

 Mich, and Minn. ; 



* * * * (FRINGED ORCHIS.) Flowers several or many in an open spike t with 



mostly foliaceous bracts; stem (rather tall) leafy; spur thread-shaped or 

 scarcely club-shaped, longer than the fringed, cleft, or dissected lip ; anther- 

 cells widely separated and usually diverging, their narrow beak-like bases, 

 supported by the arms of the stigma t strongly projecting forward or partly 

 upward. 



- Lip pectinately fringed but undivided ; flowers golden yellow or white ; anther 

 cells widely divergent, the orbicular glands as if raised on a tentacle project* 

 ing far forward or slightly inward ; ovary long, tapering to the summit. 



11. H. cristata, R. Br. Lower leaves lanceolate, elongated ; the upper 

 gradually reduced to sharp-pointed bracts, nearly the length of the crowded
