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.
