The larger acute spikelets do not match M. bulbocaulis, but the two species are 
very close.

The spikelets and nut are as those of UW. circumclusus; the bracts entirely 
want the dilated striated base seen in those of that species. As to the soft fibres into 
Which the leaf-sheaths break up, such may have been present in the examples of 
- circwmcelusus, but were not secured by the collector.
