ORCHIDACEJE. (ORCHIS FAMILY.) 



of the crowded {yellow) flowers ; spike oblong or cylindrical ; petals rounded, cre- 

 nate ; lip ovate, with a lacerate-frinyed margin, scarcely shorter than the slender ob- 

 tuse incurved spur, which is not half the length of the ovary.— Bogs, Penn. 

 (Pursh) to Virginia and southward. — Flowers one quarter the size of the next. 



10. P. ciliaris, Lindl. (Yellow Fringed-Orchis.) Leaves oblong 

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

 long-beaked ovaries ; spike oblong, rather closely many-flowered ; flowers bright 

 orange-yellow; lateral sepals rounded, reflexed ; petals linear, cut-fringed at the 

 apex ; Up oblong, about half the length of the spur, furnished with a very long and 

 copious capillary fringe.— Bogs and wet places; scarce at the North ; common 

 southward. July, Aug. — Our handsomest species, li°-2° high, with a short 

 spike of very showy flowers ; the lip i' long, the conspicuous fringe fully \> long 

 on each side. 



11. P. olephariglotfis, Lindl. (White Fkinged-Orchis.) Leaves, 

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

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

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

 holopetala (P. holopetala, Lindl.) has narrower petals with the toothing 

 obsolete, and the lip less fringed. — Peat-bogs and borders of ponds, with No. 

 10, or commonly taking its place in the North. July. — A foot high, the flow- 

 ers beautiful, but rather smaller than in the last. 



§ 5. Stem leafy : lip 3-parted, shorter than the somewhat club-sha])ed long spur, nar- 

 rowed at the base into a claw: roots clustered and fleshy-thickened.

 spike elongated, loose; petals obovate, minutely cut-toothed; divisions of the lip 

 broadly wedge-shaped or fan-shaped, many-cleft to the middle into a thread-like fringe ; 

 spur longer than the ovary. — Moist meadows, Central Ohio to Wisconsin and 

 southwestward. July. — Stem 2° -4° high ; the spike at length 1° long. Lip 

 about %' wide. 



13. P. Istcera, Gray. (Ragged Orchis.) Leaves oblong or lanceo- 

 late ; 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. (0. psycodes, Muhl., &c., not of L. 0. lacera, Michx.) 

 — Bogs and moist thickets ; rather common. July. — Stem 1° - 2° high : bracts 

 shorter or longer than the pale yellowish-green flowers. 



* * Flowers purple. 



14. P. psycodes, Gray. (Small Purple Fringed-Orchis.) Leaves 

 oblong, the uppermost passing into linear-lanceolate bracts ; raceme cylindrical, 

 densely many-flowered ; I ^wer sepals round-oval, obtuse ; petals wedge-obovate or spat- 

 ulate, denticulate above; divisions of the spreading lip broadly wedge-shaped, 

 many-cleft into a short fringe. (0. psycodes, L. ! 0. fimbriate, Pursh, Bigelow. 

 O. incisa and 0. fissa, Muhl. in Willd.) — Moist meadows and alluvial banks; 

 common. July, Aug. — Stem 2° high. Flowers short-pedicel led, crowded hi
