Two New Species of Cyrtomium (Dryopreridaceae) from Shandong

Two new species of Cyrtomium from Shandong, C.confertiserratum and C.reflexosquamatum were described. The morphology and palynology showed that Cyrtomium confertiserratum is similar to C.fortunei f. fortunei, while it differs from the latter one mainly in: the upper pinnae rhombic, the lower part 1-2 deep pinnatifid, lobes 3-4cm long, about 10 mm wide, lateral pinnaes densely serrate, indusia have small tooth on the edge, spores reniform with irregular tuberculate perine. Cyrtomium reflexosquamatum is similar to C.shandongense in morphology, but C.reflexosquamatum is larger, up to 60cm with 15-29 pairs pinnae, densely covered with anatropous scales above the pinnae bases, and spores reniform with rugate and finely fenestrate perine.
