Cellular Plants.

Cellular Plants. It was formerly attempted by De Candolle and others to unite all the lowest plants destitute of vascular tissue under the general title Cellulares, as opposed to the Vasculares, including all the higher plants. Although this classification is long disused, the term 'cellular plants' is often familiarly employed to distinguish the Fungi, Algæ, Lichens, Characeæ, Liverworts, and Mosses (q.v.) from the higher or vascular cryptogams—Ferns, Horsetails, Lycopodiaceæ and Selaginellæ, and Isoetæ. See the articles in this work on most of these groups; for cellular tissue, see also the articles BOTANY, CELL, TISSUES, LEAF, BARK, &c.
