Chorological data and threat status evaluation of Fissidens species (Fissidentaceae, Bryophyta) on Madeira Archipelago
Lobo, Carlos; Sim-Sim, Manuela; Luís, Leena; Stech, Michael
Madeira Archipelago's bryoflora includes 23 Fissidens taxa of which four are endemic to Macaronesia (Fissidens coacervatus, F. microstictus, F. nobreganus and F. sublineaefolius), including two exclusive to Madeira (F. microstictus, F. nobreganus), and several others that are considered rare or threatened in Europe. However, the distribution and threat status of several Fissidens species on Madeira Archipelago is yet insufficiently known. Based on recent field work and revision of herbarium collections, distribution data, habitat preferences, and threat status on Madeira Archipelago are updated for the Madeiran endemic F. nobreganus, the Macaronesian endemics F. coacervatus and F. sublineaefolius, as well as five other rare or insufficiently known species, F. curvatus, F. crispus, F. dubius, F. ovatifolius and F. polyphyllus.
