PLATE X.
(Plates X. to XXXIV. inclusive, are from Artis's work on the Fossil Remains of Plants, from the coal formations of Great Britain.)
"Columnar Hydatica."
Under the name Hydatica, Mr. Artis has described two species of fossil plants, from the coal-mine near Wentworth, Yorkshire. The originals appear to have been aquatic plants, having a horizontal or creeping stem, sending up slender branches, which floated by their leaves on the surface of the water.
