Abundant also in South Africa and the Mascarene Islands. ' 
This abundant species varies much in size, also in the breadth of the spikelets ; 
the young spikelets are much less compressed and look different from the ripe ones- 
It is possible to subdivide perhaps the material here collected ; but it must be noted 
(1) that the variety and species which follow are very near C. compactus, (2) thet 
none of the material should be referred (as by Boeckeler and| others) to the poe: 
C. niveus, Retz., which has much thinner glumes, and can be definitely distinguished, 
though nearly allied. ;

I concur with Boeckeler in thinking there is no difference in structure betwee?
