general taxon notes:
Un género pequeño con 3-5 especies en el Neotrópico. Tres especies están registradas en Bolivia, todos asociadas con el bosque montano de Yungas. Macrolejeunea es similar a Taxilejeunea en el hábito pero los ginoecios están en ramas laterales cortas más elevadas, sin innovaciones (rara vez con un brote estéril corto). El género algunas veces es considerado un subgénero de Taxilejeunea o Lejeunea. Adaptado o modificado de Gradstein en Gradstein et al. (2001). Traducción por Claudia Aldana (LPB).
