The Palaeozoic Calamarieae, though so far surpassing recent Equisetaceae, both in stature and complexity of organization, clearly belonged to the same class of Vascular Cryptogams. There is no satisfactory evidence for attributing Phanerogamic e bn FIG.
The only countries where the order plays a distinctly subordinate part are some extra-tropical regions of the southern hemisphere, Australia, the Cape, Chili, &c. The proportion of graminaceous species to the whole phanerogamic flora in different countries is found to vary from nearly 4th in the Arctic regions to about 2 nth at the Cape; in the British Isles it is about y2th.
The phanerogamic flora of Novaya Zemlya and Vaygach numbers about two hundred species.
His activity was by no means confined to palaeobotany, but extended into all branches of botany, more particularly anatomy and phanerogamic taxonomy.
Flora.The flora of Germany comprises 3413 species of phanerogamic and 4306 cryptogamic plants.
