abounds in spikes wholly male, whereas in C. linearis the spikes are fem., at top 
male. But in K. trinervis there occur fem. spikes shortly male or barren at top, 
and these exactly resemble spikes of C. linearis. The only diagnostic difference 
appears to be that in K. trinervis, the bracteole (homologous with utricle of Carex) 
is split on the posticous face nearly to its base so that the nut is partially protruded ; 
ne. linearis the beak of the utricle is split on the posticous face nearly (not quite) 
i Its base, so that the nut is completely inclosed in the utricle. The habit of C. 
mearis is entirely that of a Kobresia, and the two genera touch at this point.
