502 ORCHIDACE^E. (ORCHIS FAMILY.) 



12. H. ciliaris, R. Br. (Yellow Fringed-Orchis.) 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 orawjt-ytllow ; 

 lateral sepal rounded, reflexed ; petals linear, cut-fringed at the apex ; lip oblong 3 

 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, 

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

 spicuous fringe fully £' long on each side. 



13. H. blephariglottis, Hook. (White Fringed Orchis.) 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 (Platanthera 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. 



*•- +- (Greenish Fringed-Orchis.) Lip 3-parted above the stalk-like base, the 

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

 cells 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 lanceolate, trans- 

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

 gradually thickened downward. 



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

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

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

 many-cleft to the middle into a copious thread-like fringe ; spur longer than the ovary 

 (l'-l£' long); glands transversely oval. (Orchis leueophsea, Nutt.) — Moist 

 meadows, Ohio to Wisconsin and south west ward. July.— Stem 2° -4° high. 

 Lip 7" -10" long. 



15. H. lacera, R.Br. (Ragged 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 ; glauds lanceolate, as long as the stalk of the pollen-mass. 

 (0. psycodes, MuhL, &c., not of L. Platanthera psychodes, Lindl. O. lacera. 

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



+- 4- ■»- (Purple Fringed-Orchis.) Lip fan-shaped, 3-parted above the stalk- 

 like base, the dilated divisions erosely fringed : flowers purple : anther-cells tot del y 

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

 strongly projecting, the orbicular glands looking obi iquely forwards and downwards : 

 ovary contracted only at the summit. : the long curving spur somewhat thickened 

 downward. 



16. H. psyeddes, 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.
