Summary
Metaphyta is a term proposed by Rosen (1900) to designate plants with clearly expressed characteristics of plant organization, primarily the absence of mobility in the vegetative state. This concept contrasts with Protophyta, which includes plant forms that have not yet developed these characteristics.
Encyclopedia entry (1928–1936)
METAPHYTA, a term proposed by Rosen (1900) to designate plants in which the characteristics of plant organization are clearly expressed, which, in the author's opinion, manifests mainly in the absence of mobility in the vegetative state. The concept of Protophyta is opposed to it, which combines such plant forms in which the mentioned characteristics have not yet been developed. According to Rosen's views, green Flagellata, Volvocineae, Peridincae, diatoms, simplest Conjugatae, bacteria, myxomycetes and some others should be classified as Protophyta. Almost all of them are mobile in the vegetative state, although the method of movement is different in different groups. All other plants Rosen classifies as M. This division is analogous to the division of animals into Protozoa and Metazoa, but cannot be drawn with the same clarity. In botanical literature, it is now little applied, but is used in some places in zoological literature.
