Thallophyte is a term commonly used in botany to describe a type of plant that lacks a distinct floral structure and is primarily composed of a thallus or body. This group of plants includes algae, lichens, and fungi. While this term is already quite specific, there are a few synonyms that can be used to describe this group of plants. "Thallobiont" is one such synonym, referring to organisms that lack organized structures and instead have a simple thallus. "Crytogam" is another term that can be used to describe thallophytes, which refers to plants that reproduce by spores rather than through seeds. Overall, these synonyms serve to expand our understanding of this specific group of plants and their characteristics.
