POLYPODIACEAE 



MICROLEPIA CHRYSOCARPA Ching in Sinensia 1:3 (1929). 



Rhizome wide-creeping, 3-4 mm. thick, densely hirsute, sparsely rooted; stipes 

 uniseriate, scattered, 1.5-2 cm. apart, strong, rigid, densely shaggy hirsute near the 

 base, sparsely hirtellous upward, light lustrous, castaneous, sulcate, 32-40 cm long, as 

 thick as or slightly thicker near the base than the rhizome; frond broadly oblong- 

 lanceolate, not abbreviate towards base, 35-42 cm. long, 10-12 cm. broad, gradually 

 acuminate towards apex, tripinnatifid or almost tripinnate towards the base of the 

 lower pinnae; pinnae shortly petiolate, (petiole 3-4 mm. long), 14-17 on each side 

 below a deeply pinnatifid acuminate apex, the lower ones much remoter than the upper 

 (5-6 cm. apart), erect-patent, confertad above the middle, the lower ones 10-12 cm. long, 

 4-4.5 cm broad, oblong-lanceolate, slightly narrowed toward base, pinnate; pinnules 

 14-17 on each side below a short deeply pinnatifid acuminate apex, conferted, shortly 

 petiolulate, oblong-lanceolate, strongly unequal at base, 2-2 5 cm. long, 7-10 cm broad 

 pinnatifid almost down to the costa into oblong, rounded, more or less crenate lobes; 

 lobes pectinate, the basal ones on the anterior side much the largest with straight 

 inner margin parallel to the rachis of pinnae, 5-7 mm. long, 3-4 mm. broad, about 7 on 

 each side under the acute serrate apex; veins in the ultimate lobes distinct, free, 

 pinnate, 4-5-jugate, each again once-forked; sori dark brown, dense, submarginal, 

 ferminating the veinlets in the ultimate lobes, 5-6 on the basal lobes, fewer on the 

 upper ones, unisorous on the uppermost lobes, indusium brown, persistent, almost 

 rounded; texture thick, coriaceous, light green, sparsely hairy along costa above, densely 



hirtellous on the rachis, and upper side of the costa of the pinnae, much less so 

 beneath. 



Distribution: Kwangsi.
