1. Habenaria lacera (Michx.) Lodd. Ragged fringed orchid. Fig. 353. 



Plant glabrous, rather stout, 2.5-7.5 dm. tall (often propagating by means of 

 root-shoots); roots slender, fleshy, from thickened tuberoids; stem somewhat 

 ribbed, leafy below, bracted above; leaves rather rigid, erect, oblong-linear to 

 oblong-obovate or linear-lanceolate, with the basal part sheathing the stem, 7-21 

 cm long, 1.5-5 cm. wide; raceme loosely or densely flowered, 3-26 cm. long, 

 3-4.5 cm. in diameter; floral bracts usually equaling the pedicellate ovaries, rarely 

 exceeding the flowers, narrowly lanceolate to linear-lanceolate, acuminate, 1-4 cm. 

 long; flowers pale yellowish-green or whitish-green, with rather stout curving 

 pedicellate ovaries which are 1.5-2 cm. long; dorsal sepal ovate to elliptic, con- 

 cave, 4-5 mm. long, 3-4 mm. wide; lateral sepals obliquely ovate, obtuse, 4-6 

 mm. long, about 3 mm. wide; petals linear-oblong to narrowly oblong-spatulate, 

 entire or rarely toothed at the truncate or rounded apex, rarely obtuse, slightly 

 oblique, 5-7 mm. long, mostly less than 2 mm. wide; lip deeply tripartite, 10-16 

 mm. long, 13-17 mm. wide across the lateral lobes; lateral lobes deeply cut 

 (usually to the base) into three divisions, with the divisions subdivided again; 

 mid-lobe slender, clavate to narrowly cuneate or linear-spatulate, somewhat 

 spreading above into irregular slender or coarse fringes, rarely erose to short- 

 fringed at the apex, often laciniate halfway or more to the base; spur curved, 

 slender or clavellate, as long as or longer than the pedicellate ovary, 1-2.3 cm, 

 long; capsule ellipsoid, erect, about 1 .5 cm. long. 



The fringed deeply 3-lobed lip of the yellowish-green flowers is distinctive. 



In open woods along streams, in open sedge marshes and meadows in Okla. 

 (Waterfall) and n.e. Tex., rare, May-Aug.; from Nfld., s. to Ga., w. to Tex., 

 Ark., Mo., 111., Wise, Minn. 



2. Habenaria quinqueseta (Michx.) Sw. Long-horned Habenaria. Fig. 354. 

 Plant slender or stout, erect, leafy, (occasionally with the leaves mostly basal), 



glabrous throughout, 2-9 dm. tall; roots slender-fibrous, with tuberous swellings 

 (usually with an ovoid tuber at the base of the stem); leaves mainly cauline, thin 

 and chartaceous when dry, oblong-elliptic to elliptic-lanceolate or oblong-obovate, 

 broadly rounded to acute or acuminate at the apex, reduced above to clasping 

 ovate acuminate bracts, 6-25 cm. long, 2.5-6 cm. wide; raceme elongated, laxly 

 few- to many-flowered, 7-25 cm. long, 5-6 cm. in diameter; floral bracts ovate- 

 lanceolate, acuminate, semitranslucent as long as or shorter than the pedicellate 

 ovaries, 1.5-2.8 cm. long, 7-15 mm. wide below the middle; flowers greenish- 

 white, with slender pedicellate ovaries which are 2-3 cm. long; dorsal sepal 

 oblong-elliptic to suborbicular, obtuse to rarely acute, concave, 6-13 mm. long, 

 5-10 mm. wide at the middle; lateral sepals ovate-oblong to oblong-lanceolate or 

 oblong-elliptic, obtuse to acute, oblique, 8-16 mm. long, 4-7 mm. wide below 

 the middle; petals 2-parted; posterior lobe erect, linear-oblong, falcate, obtuse to 

 acute, 6-15 mm. long, about 2 mm. wide; anterior lobe filiform, almost twice as 

 long as the posterior division, recurved, 1.3-2.5 cm. long; lip 3-parted; lateral, 

 lobes filiform, recurved at the apex, 1.5-3 cm. long; midlobe linear with revolute 

 margins, 8-20 mm. long, 2-3 mm. wide; spur varying from slender to strongly 

 clavellate, recurved, 4-18 cm. long. 



Represented in Tex. by a collection by Charles Wright, without a definite 

 locality but doubtless in the Coastal Prairies in the s.e. part of the state. It 

 should be looked for in swamps, margin of ponds, and similar wet places; locally 

 distributed from Fla., n. to S.C. and w. to Tex., also in the W.I. and Latin Am., 

 July-Nov.
