Book Description
Excerpt from Description of the Coal Flora of the Carboniferous Formation in Pennsylvania and Throughout the United States, Vol. 3 Like the vegetation of the present epoch, that of the Car boniferous has been modified and diversified by local cir cumstances and is therefore differently represented at dif ferent localities if separated by a considerable distance. This can easily be seen in comparing the Coal Flora of Penn sylvania and Ohio with that of Illinois, Missouri, Kansas etc. A'certain degree of relation only is recognizable be tween the plants oi strata of the same stage; but a large number of species are only locally found. The differences in the vegetation are still more marked according to the stratigraphical distribution of the measures, or between the plants found in strata of different horizons; and as new coal fields have been recently opened and coal beds worked in Virginia, Tennessee, Alabama, Georgia, etc at a lower stage than that of the northern basins, a mass of specimens of fossil plants, not yet known in this country, have been discovered and sent from those localities.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1884 edition. Excerpt: ...without symmetrical order, short, about 3 c. m. long, 3 m. m. in diameter, linear, narrowed into a blunt apex. The bundles of spores are irregularly placed, some in small compact groups, others more disseminated or spread along some leaves as if forced by compression out of a tubular envelope or sporange. All the spores are macrospores, 1 m. m. in diameter, as figured f. 3a. The fragments show the plant in its whole length, as an agglomeration of leaves compressed from the base to the apex which is genrally broken. The texture, as seen at the surface is that of Tceniophyllum contextum, Lesqx., "Coal Flora," p. 465, PI. LXXXII, Figs. % 2a. These plants may be the young shoots of the same species. In the description of T. contextum, I remarked on the relation of the plants to Isoetes. The relation is still more evident in these short plants. But the nature and the character of the sporanges are as yet unexplained. Habitat--Cannelton. No. 774 of Lacoe's collection. Trochophyllttm, Lesqx. "Coal Flora,"p. 6S. That generic name was used, I. c, for the provisory description of vegetable remains which, in a too deficient state of preservation, could not be definitively described, and which, therefore, could not be affixed to their legitimate place until their affinities had been demonstrated by the discovery of better specimens. The first of the two species placed in the genus Trochophyllum, viz: T. clavatum, described I. c., p. 65, PI. III, Figs. 21-23, has been recognized as representing half destroyed fragments of strobiles of Sigillaria, described here below as Sigillariostrobus Laurencianus. Of the other species, T. lineare, I. c. p. 64, PI. III, Figs. 24-256, I have now received a large number of specimens which...
