Article Title



The plant -- this term is employed here to indicate a single free cell or a group of cells joined together, usually in a gelatinous matrix. A specimen or single collection may contain many plants of one or few cells mixed with other algae; it may be a single entire globule, cushion, or stratum, or a part of one of these. In the Chroococcaceae and some species of Entophysalis, plants of the same species may be found in the form of strata, cushions, or globules (both microscopic and macroscopic), or as free unattached cells.
