6. Habenaria cristata (Michx.) R. Br. Crested fringed orchid. Fig. 357. 

 Plant stout, glabrous, leafy below, bracted above, 1.8-9 dm. tall; roots fleshy, 



tuberous-thickened; leaves oblong-lanceolate to linear-lanceolate, acute to acumi- 

 nate, sheathing the stem below, 7-21 cm. long, 1-2.5 cm. wide; floral bracts 

 narrowly lanceolate, acuminate, about as long as or shorter than the pedicellate 

 ovary, 1-2.5 cm. long; raceme cylindrical, densely flowered, 2-15 cm. long, 2-4 

 cm. in diameter; flowers bright orange-colored, with slender pedicellate ovaries 

 which are 1.2-1.7 cm. long; dorsal sepal oblong-elliptic to suborbicular, often 

 slightly notched at the obtuse apex, concave, 3-5 mm. long, 2-3 mm. wide; 

 lateral sepals suborbicular to orbicular, rounded at the apex. 3-4 mm. long, 2-3 

 mm. wide; petals oblong-elliptic, often narrowly cuneate, fringed at the apex, 

 2-4 mm. long, 1-2 mm. wide; lip ovate to ovate-oblong, 4-6 mm. long, copiously 

 ciliate-fringed, with the segments usually branched (often a confusion of fringes); 

 spur 5-10 (averaging 6) mm. long, slender, much shorter than the pedicellate 

 ovary. 



In bogs, meadows, wet prairies and savannahs, along streams in woods, in 

 depressions in pine lands, and on wooded seepage slopes, in e. and s.e. Tex., 

 June-Sept.; from e. Mass. (rare), s. to cen. Fla., w. to Tex., Ark. and Tenn. 



Except for their smaller size and usually deeper color the flowers of this 

 species are similar to those of H. ciliaris. 



7. Habenaria X Chapmanii (Small) Ames. 



The size of the lemon-yellow to orange-color flowers of this plant are inter- 

 mediate between H. cristata and H. Blephariglottis, its putative parents. The 

 spur is usually about 12 mm. long. Blephariglottis Chapmanii Small. 



In habitats similar to those of H. ciliaris in s.e. Tex. (Hardin and Jefferson 

 COS.), July-Aug.; from N.J. and Del., s. to n. Fla., w. to Tex. 



8. Habenaria Integra (Nutt.) Spreng. Yellow^ fringeless orchid. Fig. 358. 



Plant glabrous, with several leaves below, bracted above, 3-6.2 cm. tall; roots 

 fleshy, tuberous, swollen near the base of the stem; stem angled; leaves oblong- 

 lanceolate to narrowly lanceolate, acuminate, with the lower part sheathing the 

 stem, 10-19 cm. long, 1-3 cm. or more wide; raceme densely many-flowered, 

 cylindrical, 2-10.5 cm. long, 2-3 cm. in diameter; floral bracts narrowly lanceolate, 

 acuminate, 1-1.7 cm. long; flowers light lemon-orange to dull-orange in color, with 

 stout pedicellate ovaries which are 5-10 mm. long; dorsal sepal suborbicular to 

 orbicular, rarely toothed at the rounded apex, concave, 3-4 mm. long, 2-3 mm. 

 wide; lateral sepals ovate-orbicular, subobtuse, oblique, 4-5 mm. long, 3-4 mm. 

 wide; petals narrowly oblong, obtuse, 3-4 mm. long, about 2 mm. wide; lip 

 ovate-elliptic to obovate, obtuse to acute, crenulate to rarely entire on the margins, 

 4-5 mm. long, 3-4 mm. wide; spur descending, tapering from a thickened base, 

 about 5 mm. long. Gymnadeniopsis Integra (Nutt.) Rydb. 



Represented in Tex. by a collection of Thomas Drummond without a definite 

 locality but doubtless in boggy savannahs or prairies in the s.e. part of the 

 state, July-Sept, along the coast from N. J. s. to n.-cen. Fla., w. to Tex.; also 

 e.-cen. Tenn. 



Except for its lack of fringes on the lip the flowers of this species are quite 

 similar in color, size and appearance to those of H. cristata. 



9. Habenaria nivea (Nutt.) Spreng. Snowy orchid. Fig. 359. 



Plant erect, slender, rigid, glabrous, 2-9 dm. tall; roots few. coarse, with 

 one or more hard ellipsoidal tubers which are to 3 cm. long and 8 mm. in diam- 

 eter; leaves 2 or 3, near base of stem, rigidly suberect, linear to linear-lanceolate, 

 acuminate-attenuate, conduplicate, strongly keeled, with the lower part sheathing
