Leaves nearly radical, 3-6 inches long, pubescent, obtuse or with a short acumination, 

 at first erect, but finally spreading. Scape 8-12 inches high. Flower larger than in the 

 preceding species ; the bract at its base large, linear-lanceolate. Sepals elliptical-lanceolate 

 (the two lower ones united their whole length), shorter than the lip, and, like the petals, 

 greenish mixed with purple. Lip 1 \ - 2 inches long, somewhat obovoid, purple, veined, 

 pendulous, with a shallow fissure or indentation in front. Sterile stamen acuminate, keeled 

 inside. Capsule elliptical-oblong, about an inch and a half in length.

 Americanum, Beck, bot. p. 352. 



Stem 6-10 inches high, sheathed with scales below, the upper part leafy, slightly pu- 

 bescent. Leaves 3 or 4, elliptical-lanceolate, 2-3 inches long, nearly smooth. Flower 

 solitary, much smaller than in any of the preceding species. Sepals and petals about three- 

 fourths of an inch long, greenish brown. Lip red and white, reticulated, the lower part ending 

 in a conical point or short obtuse spur. 



Near Oneida lake (Dr. Gray); Oneida county (Dr. Douglas § Dr. Whaley); Amster- 

 dam, Montgomery county (Mr. J. D. B. Skillman). This very rare plant was first found 

 near Montreal, about forty years ago ; and since that time, one new station for it has been 

 discovered in British America, and about half a dozen in the United States. The flower has 

 been compared in shape to a ram's head, the petals representing the horns.
