 (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

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.
