形態特徵

• Rhizome short, ascending, scaly.
• Stipes 34-37 cm long, stramineous or more or less brownish; lamina ovate, 28-33 cm long, 16-22 cm broad, imparibipinnatifid, membraneous, lateral pinnae 6-7 pairs; veins free.
• Pteris wulaiensis is morphologically intermediate between P. fauriei and P. bella. In form and texture of frond P. wulaiensis is similar to P. bella, but the shape of pinnules is almost that of P. fauriei. P. wulaiensis is easily distinguished from P. bella by its stramineous or more or less brownish but never shining axis, and from P. fauriei by its stipe-scale which has a strikingly darker central portion and translucent margins.
