1878W. R. McNab Bot.: Outl. Classif. Plants i. 2 The transition from the Thallophyta to the next sub-kingdom, the Bryophyta, is not an abrupt one, hence..in the lower bryophytes the thallus is still to be met with. 1898Science 7 Jan. 13/2 The sporophytes of many Bryophyta..have their epidermis pierced with minute openings known as stomata. 1920Lancet 17 Apr. 847/2 The Regnum Vegetable [sic]..is usually divided into four large groups, or phyla: the Thallophyta, the Bryophyta, the Pteridophyta, and the Phanerogamæ, or Flowering Plants. 1962D. C. Braungart & R. H. Arnett Introd. Plant Biol. xi. 201/1 The phylum Bryophyta is sometimes referred to as the amphibia of the plant kingdom. These plants have evolved from the algae and are examples of the first truly terrestrial plants. 2000C. Tudge Variety of Life ii. xxiii. 548 Liverworts, hornworts, and mosses..were commonly placed together in the ‘division’ known as ‘Bryophyta’; but nowadays these are acknowledged as three separate lineages and the term ‘bryophyte’ is used informally—to describe the grade. |
