FIGURE 20 in Disentangling the diversity and taxonomy of Hymenophyllaceae (Hymenophyllales, Polypodiidae) in the Mascarene archipelago, with ecological implications

FIGURE 20. Elevational distribution on each Hymenophyllaceae taxon on the windward (red plots) and leeward (blue plots) sides of La Réunion, and correspondence with thermal zones or ranges according to Cadet (1980) and provided here for the windward side, with ranges of annual average temperatures. The dotted horizontal lines correspond to the limits of leeward ecosystems. The plots indicate the average elevation. Crepidomanes trinerve is here lacking because it was only observed at a single locality on the leeward side ('Les Canots' at ~800 m). The range of each taxon, as illustrated by the vertical lines, is assumed to correspond to the range between the minimum and the maximum elevation at which they have been observed, even if the taxon has not been observed in all the intermediate localities between such limits.
