508 ORCHiDACE^. (orchis FAMILY.) 



hoidal-d Hated base, eutire, its base with tlie bases of the petals ana sepals erect- 

 couuiveut, above spreading ; anther-cells almost parallel ; ylands approxiiudte, 

 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 betweej> 

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

 northward. 



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



the plant ; scape or stem naked above, l-leaced at base {5 ~ 9' high); spur 

 not longer than the lip ; anlJier-cells wholly adnate, arcuate and wideltj sep- 

 arated. 



8. H. obtusata, Kichardson. 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 widelg 

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

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

 face of which looks obliquelg inward. 



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

 mostly naked {^-\° high), bearing 10-20 upright sessile yellowish-green ftou-- 

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

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

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

 to N. J., west to Minn, and Iowa. — Var. obloxgif6lia, 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 s\)Tesiding greenish-white fowers 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 ^ apart). — Rich woods 

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

 Mich, and Minn. 



» * * * (Fringed Orchis.) Floivers several or many in an open spike, 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, strongly projecting forward or partly 

 upward. 



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

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

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



11. H. crist^ta, K.Br. Lower leaves lanceolate, elongated ; the upper 

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