I see no distinction in other characters between fronds with indusiate and exindusiate sori. I have seen distinctly crenate lobes of suprabasal pinnae only in Blume’s type collection. One collection from limestone in Sarawak (Paul & Erwin S 27482) has somewhat elongate indusiate sori, several pairs of stalked pinnae and a bud on the upper surface of the costa of one of them; it is perhaps a hybrid. Of six known collections from the Malay Peninsula only one is indusiate. A widely distributed species but nowhere abundant.
