ORCHIDACEJE. (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 the 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 (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 (j°-l° 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-shnped petals ; spur slender, acute, about the length of the 

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

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

 oblong (3' - 5' by 1 ^' - 2'). Little Falls, New York, ./. 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 Coniferas, 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. 



*- Lip pectinate! y fringed but undivided: floivers 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.
