 grc'iiis/i-ir/u'te ; upper sepal very broad and rounded, the others and the petals 

 lance-oblonj,' ; ///) entire, linear or lanceolate, deflexed (3" lonji), about the len;>th 

 of the tai)erin<j and curvin;^ spur ; inither-ct//s arcuate and wide/// sc/ia rated. (O.

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

 at the base: spur lonc/er than the narrow entire lip: anther-cells wideli/ diverging, 

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

 mass lateralhj affixed hg a short intermediate body to the back of the orbicular 

 gland, the viscous face of which looks oblifjiielg inward {the space between the two 

 broad enough to receive the head of a butterflg). 



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

 mostly nalvcd (j°-l° high), bearing 10-20 upright sessile yellowish-green flow- 

 era 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. orbicuiata. Hook. ) — Woods, Rhode Island to Pcnn., 

 Wisconsin and northward. June. — Var. oblongif6lia, J. A. Paine. Leaves 

 oblong (3' -5' by U'-2'). Little Falls, New York, J. A. Fame. 



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

 spreading flat on the ground ; scape bractcd, bearing many spreading 7rfl«?/.s/i- 

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

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

 oblong-lanceoiatc and falcate obtuse petals ; .ymr curved, slender (about 1 4' long), 

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

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

 (H. macrophylla. Hook. Orchis orbicuiata, Fursh.) — Rich woods, especially 

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

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

 neath. Scape 1°- 2° high. 



» * * * (Fringed Orchis.) Flowers several or many in an open spike, un'tk 

 mostly folidccous bracts: stem {rather tall) leafy: spur thread-shaped or scarcely 

 club-shcprd, longer than the fringed, clefl, or dissected lip: anther-cells wideJij sep- 

 arated and usually diverging, their narrow beak-like bases, supported bi/ 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 irhitc: anther-cells 

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

 much projf cting forwards or slightly inwards: ovary long, tapering to the summit. 



11. H. erist^ta, R.Br. Lower leaves lanceolate, elongated; the uppef 

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