I may remark, however, that if the section at Malagash was exposed in a cliff like that of the Joggins, I have no doubt that more beds with erect plants would appear. The erect tree, mentioned in the section was described and figured by mc in the Proceedings of the Geological Society in January 184G. Mr Binney had described a similar specimen found in Lancashire in June 1845 ; and before the close of 1846, Mr R. Brown of Sydney had described still finer instances of tlie same kind from the Sydney Coal-field. These were the three first instances in which the Stigmaria was ascertained to be the root of the Sigillaria; of the Coal period; and even these were not altogether sufficient to dispel the doubts of some geologists. As the Malagash tree is thus an historical monument in the progress of geology, I give a sketch of it in Fig. 59. Fig, 59.âErect Sigillaria at Cape J^ ^ T (a fc) Stigmaria roots.
