2. LI PARIS, Kichard. TWAYBLADK. 



Sepals and petals nearly equal-, linear, or the latter thread-like, spreading. 

 Lip flat, entire, often bearing 2 tubei'des above the base. Column elongated, 

 incurved, margined at the apex. Anther lid-like, terminal ; pollen-masses 4, 

 in one row (2 to each cell), slightly united in pairs, without stalk, threads, or 

 gland. Small, low herbs, with solid bulbs, producing 2 root-leaves and a low 

 scape, which bears a raceme of few purplish or greenish flowers. (Xame from 

 \nrap6$,f<it or shining, in allusion to the smooth or unctuous leaves.) 



1 L. liliifolia, Richard. Leaves ovate ; petals thread-like, reflexed ; lip 

 large (1^' long), icedge-oboi'ate, abruptly short-pointed, brown-purplish. Moist 

 woodlands, N. Eng. to Ga., west to Minn, and Mo. June. 



2. L. Loeselii, Richard. Leaves elliptic-lanceolate or oblong, keeled; lip 

 obovate or oblong (2" long), mucronate, yellowish-green, shorter than the linear 

 unequal petals and sepals. Bogs, N. Scotia to Md., S. 111., and Miuu. (Eu.) 



3. CALYPSO, Salisb. 



Sepals and petals nearly similar, ascending, spreading, lanceolate, pointed. 

 Lip larger than the rest of the flower, sac-shaped, inflated (9" long), 2-poiuted 

 underneath the apex. Column broadly winged and petal-like, ovate, bearing 

 the lid-like anther just below the apex ; pollen-masses waxy, 2, each 2-parted, 

 all sessile on a square gland. A little bog-herb; the solid bulbs producing 

 a single ovate or slightly heart-shaped thin leaf, as in Aplectrum, and a short 

 (3-5' high) scape, sheathed below, bearing a large and showy (variegated 

 purple, pink, and yellow) flower. (Name from the goddess Calypso.) 



1. C. borealis, Salisb. Cold bogs and wet woods, the bulbs resting in 

 moss, with a coralloid root beneath; Maine and Vt. to Mich, and Minn., and 

 northward. Mav. A very local and beautiful plant. Lip somewhat re- 

 sembling that of a Lady's Slipper, woolly-hairy inside. (Eu.) 



4. TIPULARIA, Xutt. CRANE-FLY ORCHIS. 



Sepals and petals spreading, oblong ; the latter rather narrower. Lip pro- 

 longed beneath into a thread-like ascending spur twice or thrice the length 

 of the flower (9-12" long), 3-lobed ; the middle lobe linear, a little wavy, as 

 long as the petals, the side lobes short and triangular. Column narrow and 

 wingless. Anther lid-like, terminal ; pollen-masses 2, waxy, each 2-parted, 

 connected by a linear stalk with the transverse small gland. Herb with large 

 solid bulbs connected horizontally, on a distinct pedicel, producing in autumn 

 a single ovate nerved and plaited leaf on a slender petiole, purplish beneath, 

 and in summer a long slender scape, with 1 or 2 sheaths at base, bearing a 

 raceme of many small greenish flowers tinged with purple. (Xame from a 

 fancied resemblance of the flowers to insects of the genus Tipn/n.)
