A plant that has no true flowers or seeds, including ferns, mosses, liverworts, lichens, algae, and fungi.‘The Myxomycetes represent the only group of cryptogams with species only known from the tree canopy.’
- ‘In this subzone, herbaceous dicots, grasses, rushes, and cryptogams are dominant, and woody plants and sedges are absent.’
- ‘Students rotated from one scientist to another, assisting with data collection, and gained insight into each scientist's particular area (wetland ecology, cryptogams, syntaxonomy, floristics, or natural history).’
- ‘As in other cryptogam species, the effect of polarized red light implies that phytochrome acts at the cell periphery.’
Mid 19th century from French cryptogame, from modern Latin cryptogamae (plantae), denoting non-flowering plants, from Greek kruptos ‘hidden’ + gamos ‘marriage’ (because the means of reproduction was not apparent).
