They are, however,clearly distinguished from that order by theu seeds beuig erect not pendulous, and bytheu more comphcated ovary, which is always formed by 2 or 3 carpellary leaves,although enclosmg only one ovule, while Cordleafs have but one carpellary leaf to eachovule. The sheaths of the leaves of Cordleafs are slit, Hke those of Grasses. Sedgesstand then in the same relation to Cordleafs as Buckwheats to Chenopods. Thespecies are extremely difficult to determine, and the distinctive characters of the genei-awere unsatisfactory, until Professor Nees v. Esenbeck rearranged the Order in th
