314 ENDOGENOUS PLANTS 



f f Sepals greenish-brown, much longer than thepetals, and unlike them. 



3. P. verticill&ta, Nuttall Root of fleshy fibres ; scape with 

 a verticil (mostly of 5) obovate-oblong sessile leaves at summit, 1- 

 flowered ; sepals sublinear, tapering to a point ; lip short, 3-lobed. 

 VERTICILLATE POGONIA. 



Scape. 9 to 15 inches high, terete, succulent, often of a dingy purple color and 

 somewhat glaucous. Leaves alternate, but crowded into a verticil, 2 to 3 inches 

 long, acute at each end, often with a short abrupt acumination. Flower mostly 

 solitary, terminal, somewhat nodding (many scapes bear no flower) ; sepals 1 to 2J^J 

 inches in length, the margins involute toward the apex; petals oblanceolate, 

 obtuse ; Up papillosely crested along the middle. Gapsuk elliptic-oblong, erect, 1 

 to 1% inches in length. 

 Hob. Moist woodlands: frequent. Fl. May. Fr. July. 



Obs. The whorled leaves resemble those of Medeola. JOHN BART- 

 HAM, in 1760, speaks of it as so like that plant, that he hardly 

 knew the difference ; yet there is no affinity whatever, in the flower 

 and fruit. The long attenuated sepals remind one of the beards of 

 a cat-fish. 



425. CAt,0PO N GOJV, R. Brown. 



[Gr. Kalos, beautiful, and Pogon, beard; alluding to the bearded lip.] 



Sepals and petals distinct, spreading, nearly alike. Lip (the peduncle 

 being not twisted) on the upper side of the flower ! erect, unguiculate, 

 bearded in front. Column free, declined, winged at summit. 

 Anther sessile ; pollinia 1 in each cell. Scape from a solid bulb, 

 with a single sub-radical leaf, and a spike of red fragrant flowers. 



1. C. piilcliellus, R. Br. Leaf ensiform, or linear-lanceolate, 

 striate-nerved ; flowers bracteate, in a flexuose spike. 

 HANDSOME CALOPOGON. 



Scape 12 to 18 inches high. Leaf 6 to 9 inches long. Flowers 4 to 8 or 10 ; 

 bracts ovate-lanceolate, shorter than the ovary. Lip bearded [conspicuously with 

 whitish and orange-colored clavate hairs. 

 Hob. Swamps, among the slaty hills : not very common. Fl. June. Fr. Aug. 



Obs. This is a very elegant, as well as fragrant plant, when in 

 flower. 



TRIBE 4. NEOTTIE^AE. 



Poll-en as in the preceding tribe ; pollinia % affixed to a common gland; anther erect, 

 parallel with the column. 



426. SPIRAW'THES, Richard. 



[Gr. Speira, & twisted cord, and anthos, a flower ; the flowers being spirally arranged.] 

 Flowers somewhat ringent; lateral sepals oblique at base, and nearly 

 under or opposite the lip, the upper one adhering to the petals all 

 rather erect. Lip oblong, concave, embracing the column below, 

 with 2 callous processes near the base. Column arching; stigma 

 ovate, with a short-pointed and finally 2-cleft beak. Anther dorsal ; 

 pollinia clavate. Root fasciculate, fleshy ; scape naked, or leafy at 

 base; flowers white, in a spirally twisted spike, or obliquely re- 

 curved.
