COMMENTS

In New Caledonia, this species is known from two collections by Le Rat in South Province (Dogny and Pic Pembai) (Brotherus 1911, Maschke 1976) and one by Iwatsuki in North Province (Mt Panié) (Iwatsuki & Mizutani 1983 as Oedicladium rufescens [Reinw. & Hornsch.] Mitt.). Here we report two new specimens from North Province that allow us to confirm the presence of the subsp. rufescens versus subsp. purpuratum . M. rufescens subsp. purpuratum (Mitt.) Maschke was collected in South Province (Yaté) by Hürlimann and in North Province (Tao) by Franc (as its synonym M. rufescens var. neocaledonicum Thér. [Thériot 1910b]). The third taxa present in New Caledonia, Myurium quinquefarium Thér., is only known from the type kept at PC.
