Very slender, 3-4 dm. high : leaves 

 narrowly linear, 5-10 cm. long, 3-4 mm. 

 wide : spike short ; bracts lanceolate, 

 shorter than the flowers : these white, 

 12—15 mm. long: upper sepal ovate, 4 

 mm. long, the lateral ones lanceolate : 

 petals narrowly lanceolate, slightly 

 shorter than the upper sepal ; lip lanceo- 

 late, obtuse, dilated near the base, but 

 not rhombic ; spur one-third to one- 

 half longer than the lip, clavate towards the ape.x, acute. (P'ig. 18.) 



This plant is nearest related to L. Icucostachys, but differs in the 

 slender habit, narrow leaves and the form of the lip. The type is 

 in Lindley's herbarium, where I saw it. The specimens from 

 Lower Canada I cannot distinguish from the Alaskan specimens, 

 although the occurrence of the species on the east coast is exceed- 

 ingly remarkable.
