As per Eichler, what are the two sub-kingdoms of the plant kingdom?

Eichler's Plant Kingdom:

1. The Plantae kingdom covers plant species. They are eukaryotic and multicellular. The presence of a cell wall is a distinct feature, unlike animals.
2. Cryptogamae and Phanerogamae are two sub-kingdoms of the kingdom Plantae, as classified by Eichler.
3. Cryptogamae is a plant without flowers & seeds.
4. They reproduce by spores. Example- mosses and ferns.
5. Not all Cryptogamae are considered a part of the Plantae kingdom (Example- Fungi, now a separate kingdom).
6. Phanerogamae is a plant with flowers & seeds.
7. Plants like corn, potatoes, and coconut belonged to Phanerogamae.
