In November 1821, Professor Martins read to the Botanical Society of Ratisbon, a paper which was afterwards published in its Memoirs for 1822. This paper was entitled, "De Plantis nonnullis Antediluvianis ope specierum inter tropicos viventium illustrandis;" in it several of the species mentioned by Baron Schlotheim and Count Sternberg are referred to the orders and genera of recent plants; and the following genera are proposed:—

1. Filicites, analogous to the Arborescent ferns.

2. Palmacites, analogous to the Palmæ.

3. Bambusites, analogous to Bambusia, and other arborescent grasses; these are the
Calamites of other authors.

4. Yuccites, analogous to the Cuciphoræ, Dracenæ, Pandani, Yuccæ, and Velloriæ, of
botanical writers.

5. Cactites, analogous to the Cacti.

6. Euphorbites, analogous to the Cereiform species of Euphorbia.

7. Lychnophorites, analogous to Lychnophora, a genus of plants found by Martius in Brazil,
which belongs to the order of the Compositæ, and is allied to the Vernoniæ of Linnæus
and the Pollalestæ of Humboldt.
