Distribution | North America; South America; Eurasia; Africa; Atlantic Islands; Pacific Islands (New Zealand) |
Discussion | Species 2 (1 in the flora). Cratoneuron grows in slightly or strongly calcareous habitats that are at least periodically wet; plants have a strong leaf costa, relatively short, smooth laminal cells, and mostly lanceolate and leaflike paraphyllia. The differences between Cratoneuron and 2. Palustriella are described under the latter. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
