THE FLORA OF THE COAL FORMATION. 443 hold by numerous cord-like roots, proceeding from various heights on the lower jjart of the stem.* The fruit was a long cone or spike, bearing spore cases under scales. The Calamiles were evidently close relations of the modern horse-tails or scouring-rushes, differing principally in their great size, the want of sheaths at tlie joints, and the details of the fructification (Fig. 163). Most of the points above stated, as well as the conical form of the lower end of these Calamites, which budded out from others, were ex- plained by me in the " Journal of the Geological Society" as far back as 1849, yet the most ridiculous errors are still current in elementary books. Nine species of true Calamites have been recognised in Nova Scotia, of which seven occur at the Joggins, the most abundant being C. Suckovii and C Cistii. As just observed, the Calamites grew in dense brakes on sandy and muddy flats, in the manner of modern Equisetacece, and produced at their nodes either verticillate simple linear leaves, as in C. Cistii, or verticillate branchlets with pinnate or verticillate leaflets, as in C. Suckovii and C. nodosus. The Calamites do not seem to have contributed much to the growth of coal, though their remains are not infrequent in it. The soils in Avhich they most frequently grew were apparently too wet and liable to inunda- tion and silting up to be favourable to coal-accumulation. Fig. 164.—Equisctites (a, b) Portions of stem.
