ae Dicundus, Vahl, is a Puerto Rico plant; and the description can hardly (ad- 
nitting error in habitat) refer to C. Teneriffe, as Vahl does not describe the

e must take the earlier name of Teneriffe. The name C. nitens, Rottler, is 
Ze. but C. nitens, Retz., cannot be set aside, because almost the only certain 
thing regarding it, is that it was not a Pycreus, and therefore not the Cyperus nitens,
