Archaeplastidae is a very big group from early evolution. It can be expressed as plants, broadly defined. A big part of it are the red and brown algae, which were formerly considered to belong to the Algae of the Plant kingdom. Recently they have been split off and treated as a separate group including other one-cellular organisms. They lack chlorophyll, which the green algae and more generally the Viridaeplantae have.
In the Plant theory the first 2 groups, Rhodophyta and Glaucophyta, are treated as the first group of the Plant kingdom, connected with the Hydrogen series. As such this group is polypheletic because Chlorophyta are not included. As discussed elsewhere this is done as the group has very distinctive qualities. Evolution has led to new groups but they have very distinct qualities such as containing chlorophyll.
Very little is known about this group in homeopathy. We have few remedies.
They have a tendency of being absent. They can split into different ways of living that are very separate from each other almost like multiple personalities.
A theme that is strong is that of dementia and Alzheimer’s. It is like a return to a childlike state or an even earlier a foetal state. It is as if one becomes younger and less developed. It is like being dependent on others for energy and substance, having no separate and individual life.
Nervous: dementia, Alzheimers.
