19. Polypodiolithus.

20. Myriophyllites.

21. Phyllites.

22. Algacites, which the French translator, on obtaining the opinion of Professor Agardh,

A. Fossil plants of unknown origin, in which the stem is large, and forms the only, or at
least the most prominent character; including, 1. Lepidodendron; 2. Variolaria;
3. Calamites; 4. Syringodendron; 5. Rhytidolepis; 13. Lepidolepis.

B. Fossil plants, of unknown origin, in which the leaves form the prominent character;
including, 6. Flabellaria; 7. Schlotheimia; 8. Annularia; 9. Nœggerathia; 12. Rotularia.

C. Fossil parts of unknown plants; including, 15, Antholites; 16. Carpolites; 17. Conites.
