ORCHIDACE^:. (ORCHIS FAMILY.) 501 



8. H. Obtusata, Richardson. Leaf obovate or spatulate-oblong ; flowers 

 greenish-white ; upper sepal very broad and rounded, the others and the petals 

 lance-oblong ; lip entire, linear or lanceolate, deflexed (3" long), about the length 

 of the tapering and curving spur; anther-cells arcuate and widely separated. (O. 

 obtusata, Pursh.) Cold peat-bogs, &c., northeastern coast of Maine, and on 

 mountains of New England and N. New York to Lake Superior (chiefly sub- 

 alpine), and northward. June. (Eu.) 



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



at tJie base : spur longer than the narrow entire lip : anther-cells widely diverging, 

 their narrowed beak-like bases projecting forwards : base of the stalk of the pollen- 

 mass laterally affixed by a short intermediate body to the back of the orbicular 

 gland, the viscous face of which looks obliquely inward (t/ie space between the two 

 broad enough to receive the head of a butterfly). 



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

 mostly naked (J-l high), bearing 10-20 upright sessile yellowish-green jlow- 

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

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

 ovary (nearly 1 ' long). (H. orbiculata, Hook. ) Woods, Rhode Island to Penn., 

 Wisconsin and northward. June. Var. OBLONGirdLiA, J. A. Paine. Leaves 

 oblong (3' - 5' by 1 \' - 2'). Little Falls, New York, J. A. Paine. 



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

 spreading flat on the ground ; scape bracted, bearing many spreading greenish- 

 white flowers in a loose raceme; upper sepal orbicular, the lateral ovate; lip nar- 

 rowly linear and slightly spatulate, obtuse, drooping,. nearly thrice the length of the 

 oblong-lanceolate and falcate obtuse petals ; spur curved, slender (about 1^' long), 

 gradually thickened towards the blunt apex, twice the length of the ovary ; anther- 

 cells strongly projecting at the free beak-like base (the glands nearly \' apart). 

 (H. macrophylla, Hook. Orchis orbiculata, Pursh.) Rich woods, especially 

 of Coniferse, Maine to Pennsylvania and Lake Superior, and southward along 

 the Alleghanies. July. Leaves very smooth, shining above, silvery under- 

 neath. Scape 1 - 2 high . 



* * * * (FRINGED ORCHIS.) Flowers 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 sep- 

 arated and usually diverging, their narrow beak-like bases, supported by the arms 

 of the stigma, strongly projecting forwards or partly upwards : base of the stalk of 

 the pollen-mass mostly affixed more or less laterally to the gland. 



H- Lip pectinately fringed but undivided: flowers golden yellow or white: anther-cells 

 widely divergent and beak-pointed, the orbicular glands as if raised on a tentacle 

 much projecting forwards or slightly inwards : 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 (yellow) 

 flowers; spike oblong or cylindrical; petals rounded, crenate; lip ovate, with a 

 lacerate-fringed margin, scarcely shorter than the slender obtuse incurved spur, which 

 is not half the length of the ovary. (O. cristata, Michx.) Bogs, Penn. 

 (Pursh) to Virginia and southward. July. Flowers only a quarter as large 

 as in the next.
