Distribution:—(Hainan Island) China and Vietnam.
Ecology:—In Vietnam, Asplenium pseudopraemorsum grows in damp broad-leaved forests as a lithophyte.
Note:— Asplenium pseudopraemorsum was originally described based on a single collection from Hainan island in southern China ( Ching & Wang 1964). It is morphologically most similar to A. aethiopicum (Burman f. 1768: 32) Becherer (1935: 23), but the former is 40–45 cm tall, pinnae 3–3.5 cm long, pinna stalks 2–4 mm long, and lamina and rachis without reddish brown fimbriate scales, whereas the latter is 25–45 cm tall, pinnae 2.5–4.5 cm long and subsessile, and lamina and rachis with reddish brown fimbriate scales. This species was previously thought to be endemic to Hainan Island with very narrow distribution in China, and it appears to be very rare in Vietnam.
