In botany , plants whose seeds are not furnished with distinct cotyledons or seed-lobes. Acotyledonous plants form one of the two great divisions of the vegetable kingdom, according to the natural system. They are remarkable by increasing chiefly in length, by additions to their end; and not by addition to the outside, as in Exogens; nor to the inside, as in Endogens. They are also termed Asex′ual and Flowerle Plants , and answer to the Cryptogam i a of the Linnean system. See Acrogens , Cellulares , Thallogens , .
