Remarks

Lejeunea pulverulenta is a rather rare neotropical species that is known from Guadeloupe, Guyana and the northern Andes (Reiner-Drehwald 2005; Gradstein in press). The latter author already suggested the present synonymy based on the description and illustration of T. linguifolia by Jovet-Ast (1949). Study of the types confirmed that the two species are identical. Both were collected by l’Herminier in Guadeloupe and were described by Stephani in the same fascicle of Species Hepaticarum, as members of the genus Taxilejeunea .
