FOSSIL FLORA. 45' 



PLATE XIV. 



" Doubtful Calamite." 



These fossil stems are from the same sandstone quarry as the Calamite delineated in the 

 previous 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 ; the 

 fifth or sixth articulation is surrounded by a double line of large globular indentations, one row 

 belonging to each of the connected joints ; these imprints have apparently been left by a zone 

 of 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. Their 

 termination is unknown. 



This species is figured by M. Ad. Brongniart in Hist. Veg. Foss. tab. 18, figs. 1 — 3.
