Scirpus.] OLXxii. crPBEA0EJ3. (C. B. Clarke.) 663 



Tjothends; outer cells snbhexagonal, ultimately lax hyaline (so that a nut appears 

 microscopically hyaline-margined).— Ripe examples of this species, with fallen glumes, 

 are easily seen to belong to adrpus not Cyperus ; but young small examples are 

 difficult to distinguish from Cyperus pygmaus.
