ORCHIS FAMILY. 327 



an oval or lance-oblong closely sessile leaf near the middle, and a smaller one or 

 bract near the terminal flower, sometimes a second flower in its axil ; flower 1' 

 long, pale rose-color or whitish, sweet-scented ; sepals and petals nearly alike ; 

 lip erect, beard-crested and fringed. 



9. COBALLORHIZA, CORAL-EOOT (which the name means in 

 Greek). 



C. inuMa. Low woods, mostly N. : 3' -6' high, yellowish, with 5-10 very 

 small almost sessile flowers ; lip 3-lobed or halberd-shaped at base : fl. spring. 



C. odontorhlza. Rich woods, common only S. : 6'- 16' high, thickened 

 at base, brownish or purplish, with 6-20 pedicelled flowers, and lip not lobed 

 but rather stalked at base, the spur obsolete. 



C. multifl6ra. Common in dry woods, 9' -20' high, purplish, stout, with 

 10-30 short-pedicelled flowers, lip deeply 3-lobed, and adnate spur manifest. 



10. APLECTRUM, PUTTY-ROOT, ADAM-AND-EVE. (Name, 



from the Greek, means destitute of spur.) 



A. hyem^le. Woods, in rich mould, mostly towards the Alleghanies and 

 N. : scape and dingy flowers in early summer ; the large oval and plaited-nei-ved 

 petioled leaf appears towards autumn and lasts over winter ; solid bulbs one 

 each year, connected by a slender stalk, those of at least two years found to- 

 gether (whence one of the popular names), 1' thick, filled with strong glutinous 

 matter, which has been used for cement, whence the other name. 



11. CYPRIPEDIUM, LADY'S SLIPPER, MOCCASON-FLOWER. 



(Greek name for Vtmts, joined to that for a slipper or buskin.) Two exotic 

 species are not rare in conservatories ; the others are among the most orna- 

 mental and curious of our wild flowers : in spring and early summer. Root- 

 stocks very short and knotty, producing long and coarse fibrous roots. 

 § 1. The three sepals separate: stem leafy, one flowered. 



C. arietinum, Ram's head C. Cold bogs N. : not common ; the smallest 

 species, with slender stem 6' -10' high, oblong-lanceolate leaves, and a dingy 

 purplish flower, the sac conical and in some positions resembling a ram's head, 

 one sepal lance-ovate, the two others and the two petals linear. 



§ 2. Two of the sepals united by their edges into one under the sac or slipper, but 

 their very tips sometimes separate. 



* Stem I°-2° high, leafy to the l-3flowered summit: leaves lance-oblong or 

 ovate, with matiy someivhut plaited nerves, viorc or less pubescent: sac or 

 slipper horizontal, much injlated, open by a rather large round orifice. 



+- Sepals and linear wavy-twisted petals brownish, pointed, larger than the sac. 



C. pubdseens, Yellow Lady's-Slipper. Low woods and bogs, mainly 

 N. : sac light yellow, higher than broad, convex above ; sepals long-lanceolate : 

 flowers early summer, scentless. 



C. parvifldrum, Smaller Yellow L. In similar situations ; stems atid 

 leaves generally smaller, and flower about half the size of the other, somewhat 

 fragrant, the sac broader than high, deep yellow, and the lance-ovate sepals 

 browner. 



C. C^udidum, Small White L. Bogs and low prairies, chiefly W. : 

 small, barely 1° high, slightly pubescent ; sac like that of preceding but white. 

 •*- ■>- Sepals and petals broad or roundish and flat, white, not larger than the sac. 



C. speet&;bile, Showy L., and deserving the name, in bogs and rich low 

 woods N., and along the mountains S. : downy, 2° or more higli, with leaves 

 6' -8' long, white flowers with the globular lip (l^'long) painted with pink- 

 purple, in July. 



* * Scape naked, bearing a small bract and one flower at summit. 

 ■*- Wild species, with only a pair of oblong many-nerved downy leaves at the root. 



C. ac^ule, Stemless L. Moist or sandy ground in the shade of ever- 

 greens : scape 8-12' high; sepals and petals greenish or purplish, the latter
