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 orange-yellow; 

 lateral sepal rounded, retiexed ; 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, 

 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. blepharigldttis, 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. 



f- t- (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. leucophsfea. 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 Up broadly wedge-shaped or fan-shaped, 

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

 (!'-!' long); glands transversely oval. (Orchis leucophsea, Nutt.) Moist 

 meadows, Ohio to Wisconsin and southwestward. 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 ; glands lanceolate, as long as the stalk of the pollen-mass. 

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

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



H- >- *- (PURPLE FRINGED-ORCHIS.) Lip fan-shaped, 3-parted above the stalk- 

 like base, the 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 only at the summit : the long curving spur somewhat thickened 

 downward. 



16. H. psyc6des, Gray. Leaves oblong or lanceolate, the uppermost 

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

 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.
