 and lower stem-leaves lanceolate, attenuate, 10-15 cm. long, 1-2 

 cm. wide, withering after anthesis : spike many-flowered, but lax, 

 2-3 dm. long; bracts ovate, acute, striate, 

 about two-thirds as long as the flowers, or 



the lower almost equalling them : flowers 



greenish, 1 1 — 1 3 mm. 



long 



upper sepal

longer,

petals lanceolate, obtusish, oblique at the 



base; lip about 4 mm. long ; blade round - 



ovate, rounded at the apex, truncate at the 



base, scarcely at all hastate, thick, with prominent median ridge ; 



spur filiform, slightly clavate, almost twice as long as the lip and
