WOODSIA CINNAMOMEA Christ 



POLYPODIACEAE 



WOODSIA CINNAMOMEA Christ in Bull. Geogr. Bot. Man. 122 (1906). 



Rhizome thick, short, erect or oblique, clothed with pale-red lanceolate or linear- 

 subulate entire membranaceous scales; stipes densely tufted (5-15 together), 2-5 cm. long 

 or much longer in barren leaves, stramineous, densely clothed near the base with scales 

 similar to those on rhizome, ferruginously pilose in other parts, particularly the under 

 surface; frond usually oblong-lanceolate, 6-12 cm. long, 1.8-2.5 cm. broad, simply and 

 usually evenly pinnate, slightly reduced towards the base; pinnae sessile or subsessile, 

 horizontally patent, 8-14 on each side, opposite or subopposite, sometimes alternate, 6-8 

 mm. apart, ovate-oblong, base equal, rounded or somewhat dilated, subtruncate or 

 subcordate-truncate, crenate-serrate or deeply pinnatifid in barren leaves, 8-12 mm. 

 l° n g> 3-5 m m- broad at the base, the barren ones much broader with shortly cuneate 

 base and pinnatifid over half way down into 3-4 rounded, subentire or slightly crenulate 

 obes on each side; sori completely hidden in thick tomentum, inducium globose at first, 



ruptured at last into long-ciliate lacinae; sporangia 4-6 to each sorus, dark brown, verv 

 shortly stipitate. 



Distributions: Szechuan. 



This distinct fern belonging to § Physematium is allied to Woodsia rosthorniana 

 Diels, but differs in small more numerous pubescent longer pinnae, and stiff rachis; 

 with a habit intermediate between W. polystichoides Eaton and W. rosthorniana 

 Diels.
