An example of Llanos, marked "0. luzoncui^is Presl," is not PresPfl plant, as 
the styles are all 3-fid; it is Mariscus microcephaJus Prusl below.

In the genus Cyperus, we have in many species the primordial nut equally 
tri-onous; in the majority of species the nut is more or leas flattened on the 
anterior face (the back, of authors) so that the nut is approximately plano- 
convev in section, the stvle remaining always 3-fid. In Juncellus the "dorsal 
flattening appears to have been carried so far that the style is 2-nd; in two 
species of Juncellus, however, the style is 3-fid or 2-fid indifferently. There is 
thus no difference in structure, and no definite Hue to be drau-n between Cyperus 
and Juncellus. The only reason for retaining Juneellus as a genus is con- 
venience, even after it has been taken out, Cyperus being inconveniently large.
