376 (1911). 



Scohpendrium delavayi Franch. in Bull. Soc. Bot Fr. 32: (1885); Christ in Farnkraut. Erde 

 213; Diels in Nat. Pfl. Fam. I. 4. 233. 



Rhizome short, small, erect, clothed up to the collum with blackish lanceolate 

 subulate scales; stipes tufted, shining ebeneous, glabrous, slender, channelled above, 



obscurely undulate, 



7-12 



frond 



deeply cordate at the base with broad or rarely close sinus, 3-6 cm. across, texture 

 pellucid, light green; veins flabellate, repeatedly dichotomous, free; sort borne on the 

 secondary or tertiary veins, elongate, not attingent at the ends, inducium thin mem- 

 branaceous, persistent, opening towards each other. 



Distribution: Yunnan, Szechwan, Kweichow, also Burma. 



Distinct for its simple orbicular deeply cordate leaves, resembling those oi our 

 water lilies. The size of leaves and the length of stipes vary great deal, some plants 

 having leaves as small as 1.5 cm. across, provided with rather a long stalk, others having 

 stalks not exceeding 1 cm. in length but with rather large leaves. A fairly common fern 

 in W. China, thriving best in moist shades in wooded gorges and ravines.
