8. H. obtusata, Richardson. Leaf obovate or spatulatc-oblong ; flowers 

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

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

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

 obtusata, 1'ursh.) — 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-Ieaved 



(it tlte base: spur longer than the narrow entire lip: anther-cells widely diverging, 

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

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

 gland, the viscous face of which looks oblir/uely inward (the space between the two 

 broad enough to receive the head of a butterfly). 



9. H. Hookeri, 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, ^f.K.CAr!^ 

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



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

 Wisconsin and northward. June. — Var. obloxgifolia, J. A. Paine. Leaves 

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



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

 spreading flat on the ground; scape bracted, bearing many spreading greenish- Q4X- fl*. 

 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 orbieulata, Pursh.) — Rich woods, especially 

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

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

 neath. Scape l°-2° high. 



* * * * (Frixged Orchis.) Flowers several or many in an open spike, with 



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

 club-shajied, 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. 



■*- 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 K 

 gradually reduced to sharp-pointed bracts, nearly the length of the crowded (yellow) ^ " ' 

 flowers: spike oblong or cylindrical; petals rounded, crenate; Up orate, with a 

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

 is not half the length of the ovary. — (0. cristata, Miclix.) — Bogs, Penn. 

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

 as in the next.
