The many specimens indicate great variability. The type has rather large sori strongly impressed, and almost glabrous lower surfaces; there appears to be every gradation between this and smaller not-impressed sori. The specimens most hairy on the lower surface are from eastern New Guinea. The type of T. papuana has almost entire pinnae and strongly impressed sori. The type of Aspidium wendlandii consists of trifoliate fronds from immature plants.
