Let us take as an example of them a species very common at the Joggins, and which I have named S. Brownii, in honour of my friend, Mr II. Brown of Sydney. Imagine a tall cylindrical trunk spreading at the base, and marked by perpen- dicular rounded ribs giving it the appearance of a clustered or fluted column. These ribs are marked by rows of spots or pits left by fallen leaves, and toward the base they disappear, and the bark becomes rough and uneven, but still retains obscure indications of the leaf-scars, widened transversely by the expansion of the stem. At the base the trunk spreads into roots, but with a regular bifurcation quite un- exampled in modern trees, and the thick cylindrical roots are marked with round sunken pits or areoles, from which spread long cylindrical rootlets. These roots are the so-called Stigmarice, at one time regarded as independent plants, and, as the reader may have already observed, remarkable for their constant presence in the underclays of the coal- beds. Casting our eyes upward, wc find the pillar-like trunk, either quite simple or spreading by regular bifurcation into a few thick branches, covered with long narrow leaves looking like grass, or, more exactly, like pine leaves greatly increased in size, or, more exactly still, like single leaflets of the leaves of Cycads. Near the top, if the plant were in fruit, we might observe long catkins of obscure flowers or strings of large nut-like seeds, borne in rings or whorls encircling the stem. If we could apply the woodman's axe to a Sigillaria, we should find it very different in structure from that of our ordinary trees, but not unlike that of
