sembles the form of C. crlidta with very long cuspidate scales ; 
but is quite distinct.

Hab. Unalaschka, Meyer ; Sitcha, Bongard! — This spe- 
cies nearly resembles the preceding ; but the two are neverthe- 
less distinct. The specimen from which Prof. Dewey drew 
the description of his C. cryptocarpa approaches this species 
in form of its scales, and in the somewhat shorter fertile spikes ; 
but wholly accords with C. Silchensis in the rough leaves and 
culm, and in the fruit having a short but distinct beak ; whereas 
C. cryptocarpa has perfectly smooth leaves and culms, and the 
much broader fruit is somewhat acuminate, but not distinctly 
beaked.
