A Restiaceis. Cyperacee distinguuntur ovulo v. semine erecto 
v. nullo, et hae ratione Oreobolo solo eum illis conneetuntur. IDissiburod in tribus et genera minus 
definita evadit, jam diu optime elaborata fuit a Brownio et Kunthio, etsi characteres nonnulli quibus 
usi sunt (e.g. setarum hypogynarum absentia v. preesentia) ex observationibus posterioribus minus 
certi prestant. Divisio primaria ad flores fertiles hermaphroditos v. fcemineos a Boeckelero aliisque 
adoptata optime definita apparet, sed limites tribuum generumque majorum interdum obseuriores 
sunt, et species intermedize haud raro observantur.
