Vanden Berghen in Bull. Jard. Bot. Natl. Belg. 51: 73. 1981 . ( Plagiochilaceae ) Notes – Plagiochila barteri is reported from Madagascar , Comoros , Mauritius and La Réunion , but the var. valida was so far only reported from La Réunion ( WIGGINTON, 2018 ). It is easily distinguishable from P.barteri Mitt.var. barteri , which has previously been recorded from Madagascar ( MARLINE et al., 2012 ), by the dorsal margin almost free of teeth (or with a few ones, <6), and the bulging trigones between leaf cells ( VANDEN BERGHEN, 1981 ).
