See, on cryptogamic and other wood plants, Rossmassler, Der Wald, pp. 82 et seqq., and on the importance of such vegetables in checking the flow of water, Mengotti, Idraulica Fisica e Sperimentale, chapters xvi. and xvii.
Angiosperms are again divided into the monocotyledons, as the palms, and dicotyledons, which include most European trees. Thus: Adolphe Brongniart termed the coal era the "Age of Acrogens," because, as we shall see, of the great predominance in those times of vascular cryptogamic plants, known in Dr Lindley's nomenclature as "Acrogens." Spenophyllum cuneifolium.
The Nardoo appears generally to be considered the seed of the lentil, or some other plant of the bean tribe, whereas it belongs to one of those cryptogamic or flowerless plants, which, like ferns and mosses, do not produce perfect seeds, but are increased by cellular bodies named spores.
With the exception of a few berries, chiefly of a dwarf arbutus, the natives eat no vegetable food besides this fungus. In New Zealand, before the introduction of the potato, the roots of the fern were largely consumed; at the present time, I believe, Tierra del Fuego is the only country in the world where a cryptogamic plant affords a staple article of food.
J. Hooker will soon publish in the "Linnean Transactions" a full account of the Flora, and I am much indebted to him for the following details. Of flowering plants there are, as far as at present is known, 185 species, and 40 cryptogamic species, making together 225; of this number I was fortunate enough to bring home 193.
In the light of the Bible genesis, science can account for the origin of the stalwart oak or the lordly pine, without going back to any mycological or cryptogamic forms, to follow down an ever-changing vital plexus that is as likely to land in a buttonwood tree as an oak, or in a hemlock as a pine, in fact, quite as likely to land in a carnivorous animal as in an insectivorous plant.
A denser air, it was suggested, had in earlier times been alike adverse to the well-being of the higher order of flowering plants, and of the quick-breathing animals, such as mammalia and birds, while it was favourable to a cryptogamic and gymnospermous flora, and to a predominance of reptile life.
Of flowering plants there are, as far as at present is known, 185 species, and 40 cryptogamic species, making altogether 225; of this number I was fortunate enough to bring home 193. Of the flowering plants, 100 are new species, and are probably confined to this archipelago. Dr.
The variety of small, beautifully-shaped ferns, lichens, and boleti, made the place quite a museum of cryptogamic plants. We then continued our voyage, and in the evening arrived at Villa Nova, a straggling village containing about seventy houses, many of which scarcely deserve the name, being mere mud-huts roofed with palm-leaves. We stayed here four days.
Cryptogamic vegetation would have the advantage over Phanerogamic; Hydrozoa over Corals; Crustacea over Insecta, and Amphipoda and Isopoda over the higher Crustacea; Cetaceans and Seals over the Primates; the civilisation of the Esquimaux over that of the European.
