Lychnophorite. (Lychnophorites superus, of Artis.)

The formof the cicatrix and point of attachment is shown at b ; figure A, is the restored outline of a leaf. Dr. Martins refers the fossil plants of this type to a recent shrubby genus of syngenesiousplants, which cover the plains of Brazil, and which he names Lychnophora, whence he formedthis fossil genus, by changing the termination to ites, according to the common usage.—Artis. The specimen represented is in sandstone, from Swinton Common, near Rotherham, York-shire. This tree seems to be closely allied to the Lepidodendra. i. r„>/,:/J,Y, yLil//::<^ fOSSIL FLORA. 73 PLATE XXVIII. Eared Neuropterite. {Neuropteris auriculata, Brongniart. Hist. Veg, Foss, tab. Osniunda, of Artis.) The general aspect of this beautiful filicite very much resembles that of our well-knownflowering fern, the elegant Osmunda regalis; the auriculated or one-eared base of the lanceolatedleaflets forms, however, a distinguishing character. It belongs to the genus Neuropteris (nerved-leaf fern) of M. Brongniart, which comprises many species of delicately-veined ferns : the veinsin this fossil plant are very fine, arched, and rise obliquely from the base of the leaflet. The leaflets are often found detached, and in many instances, though completely carbonized, are so firm, and so slightly attached to the shale, that they may be separated by a pair of forceps: when removed, their impression remains on the stone, as is shown in the light-coloured part of the figure 2 ; the form and distribution of the rib, and nervures
