TYPE. — Madagascar, Prov. Antsiranana, “Réserve Spéciale de Manongarivo (13°59’N, 48°26’E), on the rain forest covered north ridge leading to the 1869 m high summit of Manongarivo Massif, Epiphyllous”. P. Geissler 19856/1 (holo-, G; iso-, EGR, JE, TAN).

ETYMOLOGY. — Named after the late Patricia Geissler, hepaticologist and former curator of the bryophyte collection of Geneva herbarium, who first collected this taxon.
