H. hyper- H. hyperborea var. purpurascens {Rydb.) comb. nov. 



borea var. Limnorchis purpurascens Eydb., in Bull. Torr. Bot. CI. 28 : 

 purpuras- ^^^ ^ ^^^ ^^^^^^^ 



"A rather stout plant, 3-5 dm. high, with fleshy-fibrous roots. 

 Leaves ovate to lanceolate, acute, 6-10 cm. long, 1.5-3 cm. wide, 

 dark green : bracts lanceolate, the lower exceeding the flowers : 

 spike rather dense: flowers 10-12 mm. long: lateral sepals green, 

 oblong-linear, or linear, obtuse, 4-5 mm. long; the upper sepal 

 tinged with purple, broadly ovate, erect, obtuse : petals slightly 

 shorter, erect, purple, lanceolate, oblique: lip broadly linear- 

 lanceolate, about 5 mm. long, purplish, scarcely at all dilated at 

 the base, the edges almost straight: spur scarcely more than 

 half as long as the lip, much thickened and saccate. 



"This species belongs to the L. hyperborea group, and is 

 perhaps nearest related to that species. It differs, however, in 

 the purple petals and lip and the shorter and more saccate spur. 

 The spur has almost the same form as that of L. stricta; but 

 from that species it differs in the dense spike and the broader 

 lip. L. purpurascens grows in damp woods at an altitude of 

 2700-3000 m.
