#cryptogams
- Acrogenous — Regarding plants or structures; developing, growing, or originating exclusively at the tip, apex, or upper extremity, typical of vascular cryptogams like ferns.
- Amphigamous — Relating to amphigamy or presenting the characteristics of this state; describes cryptogamous plants (such as mosses or ferns) whose reproductive organs or fertilization modes are not obvious or structured in the form of visible flowers, reproduction being based on the alternation of generations and the hybrid fusion of hidden gametes.
- Antheridium — A masculinized grammatical form or secondary lexical variant for the term 'antheridium', sometimes used in archaic scientific literature or direct translations to denote the male reproductive organ of cryptogamic plants. This structural element fulfills the biological role of a gametangium in which ciliated or flagellated mobile male gametes differentiate, necessary for the fertilization process in an aquatic medium.
