Mariscus setiglumis C. B. Clarke. 
Mss. in herb. Kew. 1891. 
There is much of this from South Brasil in herb. Kew. — It differs by the 
minute bristly mucron from numerous closely allied spec. (Cyperus rigens Presl. 
— C, Ietus Kunth non Presl.). 
It will be alternative here, either to admit M. setiglumis as a distinct species. 
or to unite several of the neighbouring species.
