CYSTOPTERIS MOUPINENSIS Franchet 



■ POLYPODIACEAE 



CYSTOPTERIS MOUPINENSIS Franch. in Nouv. Arch. Mus. 2. 10: III (1887); C. Chr. Ind: 



Suppl. 46 (1913-17); Hand-Mzt. in Symb-Sinic. VI: 20 (1929). 



Davalia triangularis Baker in Ann. Bot. 5: 202 (1891). 



Rhizome slender, wiry, wide, creeping, subglabrous; stipes slender, elongate, far 

 apart, 10-15 cm. long, greenish, glabrous; frond deltoid-ovate, subtripinnate, 10-17' cm. 

 long, 6-10 cm. broad at the base, attenuate to the fine acuminate or caudate apex; 

 pinnae all petiolate, erect-patent, 2-3 cm. apart, alternate, the basal ones lanceolate^ 

 4-7 cm, long, 5-2.2 cm. broad, acuminate, cuneate at the base; pinnules subrhombic- 

 ovate-oblong, about 6-1 1 on each side, the upper inner base straight, the lower cut 

 away to the costa, the lower ones pinnate or deeply pinnatifid towards the base; lobes 

 ovate, with rounded inciso-dentate apex; texture thin herbaceous; sort mostly 6-8 

 sometimes only 3 to each pinnule, dorsal on the veinlets; inducium glabrous, thin 

 membranaceous, at last evanescent. > . 



Distribution: Szechuan, Yunnan, Tibet. 



A fairly uniform and distinct endemic species, closely related to C. sudetica A. 

 Br. et Milde, differs in glabrous inducium, smaller frond and cutting. First discovered 

 by Pere David in Tibet, later by Delavay in Yunnan and again by Wilson in W. 

 Szechuan. Our figure is drawn from Wilson's No. 5311.
