=Flowers= 1, sometimes 2, terminal, nodding, rather large for plants; rose and purplish-yellow; fragrant, subtended by a foliaceous bract. =Labellum= free, somewhat appressed to the column below, fringed and spurless. =Sepals= and =petals= about equal, similar. =Stem= 8-15 inches high. =Leaves= 1-3, rarely 1 basal leaf; the stem-leaf is ½-3 inches long, bluntly acute; foliaceous bract subtending seed-capsule. _Continental Range_—From Newfoundland, southward to the pine barrens of Alabama and Florida; westward to Minnesota and Kansas. _New England Range_—Maine, common; New Hampshire, common; Vermont, common; Massachusetts, common; Rhode Island, common; Connecticut, common. 2.—POGONIA TRIANTHOPHORA (Swartz) B. S. P., 1800-1888[76] NODDING POGONIA The specific name, _trianthophora_, refers to the 3-lobed labellum and the usually 3 nodding flowers of this species. Small woodland orchid, with tuberous roots. July-August 11th-September 24th. =Flowers= 1-7 on axillary peduncles, pale purple, at first nearly erect, soon drooping, ½-⅔ inch long. =Labellum= 3-lobed, clawed, roughened, without a spur. =Sepals= and =petals= equal, connivent. Stem 3-8 inches high. =Leaves=, 2-8, alternate, ovate, clasping stem. =Seed-capsule= oval, drooping. _Continental Range_—From Canada, southward to North Carolina, Alabama, and Kentucky; westward to Illinois, Missouri, Iowa, and Indiana. _New England Range_—Maine, rare; New Hampshire, infrequent; Vermont, rare; Massachusetts, rare; Rhode Island, rare; Connecticut, infrequent. 3.—POGONIA VERTICILLATA (Willdenow) Nuttall, 1805-1818 LARGE WHORLED POGONIA The specific name, _verticillata_, refers to the whorled or verticillate growth of the leaves. Small moist woodland orchid, with fleshy-fibrous creeping roots. May 20th-June 15th. =Flowers= solitary, purplish-green, and yellow, erect or declined, terminal; peduncle ½-⅔ inch long, in fruit exceeding the seed-capsule. =Labellum= 3-lobed, crested along a narrow band, upper part expanded, greenish-yellow. =Sepals= linear, 1½-2 inches long, ¹⁄₁₂ inch wide, spreading, dark purple; =petals= linear, obtuse, greenish-yellow, ⅚ inch long. =Stem= 10-12 inches high, round and purplish. =Leaves= 5, verticillate, in a whorl strongly recalling the whorls of the Indian Cucumber plants (_Medeola_), with which it grows in company; obovate, terminal, pointed at apex, 1-3 inches long. Rarely an obovate basal stem-leaf occurs below the whorl. The roots distinguish this plant from Indian Cucumber, yet many times the two plants so closely resemble each other that it is difficult to determine one from the other until the roots are revealed. The stem of the _Pogonia_, however, is larger, fleshy, purplish, and juicy, while the Indian Cucumber is brittle and slender. _Continental Range_—From Ontario, Canada, southward to North Carolina and Florida; westward to Michigan and Indiana.
