POLYPODIACEAE 
POLYPODIUM MANMEIENSE Christ, Bull. Herb. Boiss. 6: 870 (1898); Bull. Acad. Géogr. 
Bot. (1906) 104; Bull. Soc. Bot. France 52: Mém. 1. 13 (1905); C. Chr. Ind. Fil. 
543 (1906). 
Polypodium simulans Baker, Kew Bull. (1906) 13. 
Rhizome rather slender, wide-creeping, epigaeous, clothed in moderately dense, 
lanceolate, long-acuminate, sparcely denticulate, sorbid-brown scales; frond distant, erect, 
stipe rather slender, naked, pale straminous, 10-15 cm long, lamina lanceolate, simple 
pinnate, 20-34 cm long, 5-6 cm broad, base truncate, apex caudate with gross serration, 
texture herbaceous, pale green, naked in all parts; pinnae numerous, horizontally patent, 
3-3.5 cm long, 4 mm broad, linear-lanceolate, decurrent, or rarely with the lower few 
pairs adnate to the wingless rachis, the basal ones generally slightly abbreviated with 
low and remote teeth; veins free or with open areolae; sovi small, globose, superficial, 
placed midway between costa and margin.

In habit, this species appears exactly like P. microrlizoma Clarke from the same 
locality and the neighbourhood, differs only in open venation, shorter, pale-colored 
stipe and shorter pinnae of somewhat thicker texture; from P. vulgare L. it differs chiefly 
in slender habit, thinner texture, narrower segments with much broader interspaces, and 
having veinlets of contiguous groups with a greater tendency to join into a row of some- 
what open costal areolae.
