A pictorial atlas of fossil remains, consisting of coloured illustrations selected from Parkinson's "Organic remains of a former world," and Artis's "Antediluvian phytology." . C,n/.AJr/. y/,. a FOSSIL FLORA. 45 PLATE XIV. Doubtful Calamite. These fossil stems are from the same sandstone quarry as the Calamite delineated in theprevious plate. They differ in some respects from the usual type of the genus, lience the specific name{Galamites dubius). The strise are narrow, and have a fine groove running down the middle ; thefifth or sixth articulation is surrounded by a double line of large globular indentations, one rowbelonging to each of the connected joints; these imprints have apparently been left by a zoneof some organs which surrounded the articulations, and by its pressure left the indented frill,shown in the upper extremity of fig. 2. These stems are generally found compressed, and from two to three feet in length. Theirtermination is unknown. This species is figured by M. Ad. Brongniart in Hist. Veg. Foss. tab. 18, figs. 1—3.
