Selliguea tafana


Asia-Tropical, Papua New Guinea present
Malesia: scattered throughout the mountain ranges of Papua New Guinea.


3. Selliguea tafana was described on the basis of a larger, laxer form, with few persistent scales. A few specimens have some radially organised shoots, a feature that is more common in S. ferrea. 2. The most common form of this species was described as Polypodium squamisorum. This form is compact, and several specimens of this form have many persistent scales on the lamina and especially in the sori, giving them a highly characteristic appearance. This is only one extreme of a variable character: other specimens have few or very few persistent scales. 1 Most easily recognised (if the characteristic persistent soral scales are absent) by the narrowly ovate-elliptic sterile fronds, and the fertile fronds being nearly always not only narrower but also shorter than the sterile ones. Selliguea tafana is not always clearly distinct from S. lauterbachii, with which it co-occurs in the lower end of its altitudinal range.
