Var. (?) purpuriceps, C. B. Clarke. Leaf broader up to 23 in. wide. Head 
rather looser, a purplish tinge in the dried example; bracts tu the spikelets $ in. 
long, rather broader; the two glumes to the 1-staminate flowers very pubescent on 
the keel. Style with 2 very long branches.

The specimen is in young flower and without the lower stem and leaves, It is 
probably specifically separable from MZ. subcomposita, as the very long style-branches 
here present could hardly become short in fruit.

_ One of G. Mann’s examples has the bracts sessile and truncate at the base, the 
other has the bracts long attenuate and quasi-petioled. These may represent two 
distinct species ; but G. Mann has numbered both 1639.
