502 OECHIDACE^. (orchis FAMILY.) 



12. H. eili^is, E. Br. (Yellow Fbinged-Oechis.) Leaves oblong or 

 lanceolate ; the upper passing into pointed bracts, which are shorter than the ova- 

 ries; spike oblong, rather closely many-flowered; flowers bright orange-t/eltow ; 

 lateral sepal rounded, reflexed ; petals linear, cut-fringed at the apex ; lip oblong, 

 about half the length of the spur, furnished with a very long and copious capillary fringe. 

 (0. ciliaris, L.) — Wet sandy places, New England to Michigan, and especially 

 southward : rare north of New Jersey. July - Sept. — Our handsomest species, 

 1^° - 2° high, with a short spike of very showy flowers ; the lip i' long, the con- 

 spicuous fringe fully i' long on each side. 



13. H. blepharigl6ttis. Hook. (White Fringed Oechis.) Leaves, 

 &c. as in the last; flowers white; petals spatulate, slightly cut or toothed at the 

 apex ; lip ovate- or lanceolate-oblong, with the irregular capillary fringe of 

 the margins usually shorter than its disk, one third the length of the spur. — 

 Var. HOLOPETALA (Platanthcra holopetala, Lindl.) has narrower petals with 

 the toothing obsolete, and the lip less fringed. — Peat-bogs and borders of 

 ponds, with the preceding, commonly taking its place in the northward. July. 

 — A foot high, the flowers beautiful, but rather smaller than in the last. 



H- I- (Gkeenish Fkinged-Okchis.) Lip 3-parted above the stalk-like base, the 

 divisions cut into capillary fringes : flowers greenish- or yellowish-white : anther- 

 cdls not very divergent, the beaked bases, supported on the upper edge of the broad 

 arms of the stigma, projecting forwards ; the large glands oval or lanceol-ate^ trans- 

 verse, nearly facing each other : ovary short-tapering at the summit : the long spurs 

 gradually thickened downward. 



14. H. leucophfea. Leaves oblong-lanceolate ; the bracts similar, rather 

 shorter than the (large) flowers ; spike commonly elongated, loose ; petals obo- 

 vate, minutely cut-toothed ; divisions of the lip broadly wedge-shaped or fan-shaped, 

 Tnany-clefl to the middle into a copious thread-like fringe ; spur longer than the ovary 

 (I'-lJ' long); glands transversely oval. (Orchis leucophtea, iVatt.) — Moist 

 meadows, Ohio to Wisconsin and southwestward. July. — Stem 2° -4° high. 

 Lip 7" -10" long. 



15. H. l^cera, E.Br. (Eagged Fringed-Orchis.) Leaves oblong or 

 lanceolate; raceme loosely many-flowered; petals oblong-linear, entire; divisions 

 of the lip narrow, deeply parted into a few long nearly capillary lobes ; spur about the 

 length of the ovary ; glands lanceolate, as long as the stalk of the pollen-mass. 

 (0. psycodes, Mvlil., &c., not of i. Platanthera psychodes, Lindl. 0. lacera, 

 Michx.) — Bogs and moist thickets : common. July. 



-1- 1- ■!- (Purple Fringed-Orchis.) Lip fan-shaped, Z-parted above the stalk- 

 like base, tile dilated divisions erosely fringed : flowers purple : anther-cells widely 

 separated, but little divergent, their tapering bases {supported as in the preceding) 

 strongly projecting, the orbicular glands looking obliquely forwards and downwards: 

 ovary contracted oflly at the summit ; the long curving spur somewhat thickened 

 downward. 



16. H. psycddes, Gray. Leaves oblong or lanceolate, the uppermost 

 passing into linear-lanceolate bracts ; raceme cylindrical, densely many flowered ; 

 lower sepals round-oval., obtuse; petals wedge-obovate or spatulate, denticulate above ; di- 

 visions of the spreading lip broadly wedge-shaped, many-cleft into a short fringe.
