|discussion=<p>Species 2 (1 in the flora).</p><!--
--><p>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.</p>
