Characterized by its very short and saccate spur, which is scarcely 

 more than half as long as the lip. The flowers are often more 

 or less purplish. As the lower bracts are sometimes rather long, 

 it has been confused with Coeloglossiini hractcatuni, in which, 

 besides the differences in the stamen, the lip is retuse or 2-lobed at 

 the apex. It has often been labelled Habenaria hypcrborea, to which 

 it is nearest related ; it has, however, a longer spike, larger flowers 

 and more strongly saccate spur. In swamps, at an altitude of 1500— 

 2500 m.

In general habit it most resembles H. hypcrborea, but has larger 

 white flowers and a dilated lip, as in //. dilatata. From the latter 

 it differs in the less dilated lip and the spur, which seldom equals 

 the ovary in length and is more or less saccate. It is common in 

 marshy places at an altitude of 1500-2500 m.
