lateral ones ovate-lanceolate, obtuse, spreading : petals lance- 

 olate, acute, oblique, a little shorter than the sepals ; lip 5-6 mm. 

 long, ovate-lanceolate, obtuse ; spur almost equalling or some- 

 what exceeding the lip, distinctly clavate and curved. (Fig. 5.) 



This is the most common species in Greenland, but also found 



on the North American continent.

in the stouter habit, the larger flowers, the broader lip and the 

 clavate spur. It is more common than the specimens cited below 

 seem to indicate, but I have cited here only the specimens in our 

 herbaria, as these are the only ones presently at hand.

large, longer than the flowers, with sca-

 about 5 mm. long ; lateral ones lance- 

 olate or oblong, 5-6 mm. long: petals 

 green or purplish, lanceolate, acute; lips 

 lanceolate, obtuse, about 6 mm. long ; spur filiform, i. e. $ not at 

 all clavate, curved, slightly longer than the lip. (Fig. 6.) 



This is nearest related to the preceding, but still stouter, and 

 differs in the narrower lip and more slender, not clavate spur. 

 In habit it is intermediate between L. major and L. dilatata, and 

 has been confused with both. The name refers to this fact and 

 not to the size, for it is the largest species of the hypcrborca 

 group.
