ORCHIDACE^E. (ORCHIS FAMILY.) 453 



1. C. iimfita, R. Brown. Plant slender, light brownish 01 yellowish 

 (5' -9' high), 5-12-flowered ; lip somewhat hastdtely 3-lobed above the base, the 

 lamellae thick and rather short; spur none; pod oval or elliptical (3 '-4" long). 

 (C. verna, Nutt.) Swamps and damp woods, throughout; but scarce. May, 

 June. (Eu.) 



2. C. in u Iti flora, Nutt. Plant purplish, rather stout (9' -18' high), 

 10-30-flowered; lip deeply 3-lobed at the base; the middle lobe very wavy, re- 

 curved, the lamellae occupying a great part of its length ; spur a manifest protu- 

 berance; pod. oblong (i'-f long). Dry rich woods; common, especially 

 northward. July -Sept. Flower much larger than in* the last: sepals and 

 petals 3" -4" long. 



* * Lip not at all lobed (mostly purplish, but unspotted) ; the lamettce consisting of 

 short and tooth-like processes near the base. 



3. C. odontorhiza, Nutt. Plant light brown or purplish ; stem rather 

 slender, bulbous-thickened at the base (6' -16' high), 6 - 20-flowered ; flowers 

 small, on rather slender pedicels ; lip (2" -3" long) obovate or ovate with a short 

 narrowed base, flattish, with the margin wavy and obscurely denticulate ; spur ob- 

 solete; pod oval (3" -5" long). (C. Wistariana, Conrad, is merely a larger 

 form.) Rich woods, W. New England and New York to Michigan and south- 

 ward ; common. May -Aug. Flowers intermediate in size between No. 1 

 and No. 2. There is a small tooth, more or less evident, on each side, where 

 the base of the lip and the wing-like margin of the column join. 



4. C. RIsicr&i, Gray. Plant purplish, stout (6' -16' high), bearing 15- 

 20 large flowers in a crowded spike, on very short pedicels ; lip oval, very obtuse, rath- 

 er fleshy (purple), 3-nerved, perfectly entire, concave, the margins incurved, the 

 sessile base obscurely auricled and with 1-3 short lamellae ; spur none at all ; 

 pod ovoid (i'long). Woods, along Lakes Huron and Superior (Mackinaw, 

 C. G. Loring, Jr., Whitney, &c., West Canada, W. F. Macrae. ) Sepals and 

 petals 6" - 8" long, conspicuously 3-nerved ; but this cannot be C. striata, LindL, 

 which is said to have a 3-lobed and acute lip, &c. Flowers the largest of the 

 genus. 



16. APL.ECTRUM, Nutt. PUTTY-BOOT. ADAM-AND-EVE. 



Sepals and petals much as in the last. Lip with a short claw, free, 3-lobed, 

 the palate 3-ridged ; no trace of a spur. Anther slightly below the apex of the 

 cylindrical straightish column : pollen-masses 4. Scape and raceme as in Co- 

 rallorhiza, invested below with 3 greenish sheaths, springing in May from the 

 side of a thick globular solid bulb or corm (filled with ex teedingly glutinous 

 matter), which also produces from its apex, late in the preceding summer, a 

 large, oval, many-nerved and plaited, petiolcd, green leaf, lasting through the 

 winter. (Genus too near the last? The name composed of a privative and 

 trX^Krpov, a spur, from the total want of the latter.) 



1. A. hyemale, Nutt. Woods, in rich mould : rare. Solid bulbs of- 

 ten 1' in diameter, one produced annually on a slender stalk, along with fibroua
