THELYPTERIDACE/ 
STEGNOGRAMMA CYRTOMIOIDES (c. Chr.) Ching in Sinensia 7: 95 t. 3. 1936. 
Dryopteris stegnogramma var. cyrtomioides C. Chr. in Acta Hort. Gotheb. 1: 56. 1924. 
Rhizome oblique or short-creeping; fronds caespitose at the growing apex of the rhizome, stipe slender, 
8-14 cm long, dark stramineous, the basal part is both sparsely scaly and hirsute, scales dark brown, ovate- 
lanceolate, acuminate and setose, hairs pale-colored, needle-like, spreading, multicellular, the upper part of 
stipe and the entire rachis are similarly hirsute, lamina 14.24 cm long, 45 cm broad, broadly lanceolate, 
acuminate, slightly narrowed towards the base, simply pinnate under the deeply pinnatifid apical part; 
pinnae 7-10 pairs, more or less adnate, only several lower pairs free and sessile, slightly shorter than the 
middle ones, which are 2.5-4 cm long, 1.31.5 cm broad at the broader round-truncate base, ovate-lanceolate, 
acute or short-acuminate, the lowest pair less than 2 cm long, oblong-ovate, patent or often somewhat de- 
flexed, the upper ones patent, separated by rather narrow sinuses, margin subentire or more often undulate- 
crenate; zexture thickly herbaceous, flavo-greenish, or blackish, both sides moderately and shortly hirsute on 
costa, veins and veinlets; lateral veins 8410-jugate, distinct, subpatent, pinnate; veinlets 4-3 pairs, obliquely 
ascending, slightly curved, of which usually only the basal pair of opposite groups united into a triangular 
mesh along each side of the costa with excurrent veinlet running towards the margin as the upper veinlets; 
sort linear, along the lower several veinlets of each group, of which the lowest are much longer than those 
above, densely hirsute due to the setose sporangia.

This distinct species is endemic in West China. In habit, it resembles Cyrtomium Fortunei Ja.Sm.. £.
