[The Central Australian plant can be distinguished from the typic form as 

 var. fasciiuligeriis, inasmuch as the spikes are shortened almost all to fascicles 

 with a tendency to ramification. But similar \ariations may be observed in some 

 other species of Cyperus, for instance our C. litcidiis. The plant bef(jre us has the 

 radical and floral leaves also narrower than usual, which is doubtless from the 

 efiect of desert clime. F. v. i\l ] The whole plant is \ery viscid.
