Copeland distinguished Cyclosorus viridis by the green (not dark) colour of dried fronds, narrower pinnae and the presence of small indusia. All these characters appear to be variable. Very young fronds of plants in cultivation at Kew develop a coat of mucilage, as in P. callosa. Small indusia, not as large as a mature sporangium, are found in some sori of these plants. Ramos & Edano, BS 49586, from Mindanao (collected in 1927) was distributed as Dryopteris todayensis Christ?.
