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

 li° - 2° high, with a short spike of very sliowy flowers ; the lip i' long, the con-

13. H. blephai'iglottis, Hook. (White Fiuxged Oncms.) Leaves, 

 &c. as in the last; Jhwers white; j^etals 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 tiie spur. — 

 Var. noLOPETALA (Platanthera holopctala, 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. 



-t- 1- (Grkenish Frixged-Orchis.) Li/t3-parlcdahore the stalk-like Ixisr, the 

 divisions cat 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 doivnward. 



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

 shorter than the (lar^c) flowers; spike commonly elongated, loose; petals obo- 

 cate, minntely ciil-toothal ; divisions of the lip broadly wedge-shaped or fun-shaped, 

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

 (l'-l|' long); glands transversely oval. (Orchis leucophiX'a, iV^^/.) — Moist 

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

 Lip 7" -10" long. 



15. H. lacera, R.Br. (Bagged Fringed-Orchis.) Leaves oblong or 

 lanceolate ; raceme loosely many-flowered ; petids 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, Mvhl., &.C., not of Z. Platanthera psychodes, LIndl. 0. lacera, 

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



-t- -1- -f- (Purple Frixgkd-Orciiis. ) Lij> fan-shaped, S-parted above the stalk- 

 like base, the dlintxd divisions ero-^ely fringed : fowers pyurple : anther-cells widely 

 separated, but little divergent, their tapering bases {supported as in the ]>recedlng) 

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

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

 downward. 

 IC. H. psyc6des, Cray. Leaves oblong or lanceolate, the uppermost 

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

 lower sejxds 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.
