Schimper^ speaks of this species as possibly the pith-cast of Equisetites columnaris, but his opinion cannot be main- tained; the species first described by Bunbury has considerably larger stems than those of E. columnaris. It is not impossible, however, that E. columnaris and E. Beani may be portions of the same species. The chief difference between these forms is that of size; but we have not sufficient data to justify the inclusion of both forms under one name. Zigno'', in his work on the Oolitic Flora, figures an imperfect stem cast of E. Beani under the name of Calamites Beani, but the species has. Fig. 60. Mquisetites Beani (Bunh.). f nat. size.
