[223-A] In this and subsequent remarks on fossil plants I shall often use Dr. Lindley's terms, as most familiar in this country; but as those of M. A. Brongniart are much cited, it may be useful to geologists to give a table explaining the corresponding names of groups so much spoken of in palæontology.
| Brongniart. | Lindley. | ||||
| Cryptogamic. | { | 1. Cryptogamous amphigens, or cellular cryptogamic. | Thallogens. | Lichens, sea-weeds, fungi. | |

| Phanerogamic. | { | 3. Dicotyledonous gymnosperms. | Gymnogens. | Conifers and Cycads. | |
| 4. Dicot. Angiosperms. | Exogens. | Compositæ, leguminosæ, umbelliferæ, cruciferæ, heaths, &c. All native European trees except conifers. | |||
