broad, smooth, and having very few thick pinnae, usually seven, 

 obliquely oblong-lanceolate, falcate, and. being serrulate irregu- 

 larly; the lowest stalked, and. unequally cordate at the base; 

 the upper pinnse sessile and. decurrent. 



The pinnae of the barren fronds are somewhat undulated. 

 The stipes exceedingly stout at the base, where it is covered, 

 with long, narrow, pointed scales. 



In the fertile fronds, which are entirely covered with sori, 

 the stipes is longer, and the pinnae are more contracted. 



Sori very large and numerous, being a large mass of elevated 

 spore-cases irregularly bi-tri-serial, at first pale green, and 

 afterwards black. 



Yeins having club-shaped apices. 



Rhizoma erect. 



Introduced into Great Britain by M. Yan Houtte, of Ghent, 

 in 1852. 



This species was discovered in China, by Dr. Von Siebold. 



Stipes scaly below, ebeneous, except along the under edge, 

 where green. 



Fronds adherent to a broad rhizoma. 



Length of frond from twelve to fifteen inches, the leafy 

 portion being as broad as it is long. Breadth of barren pinnae 

 one inch and three-quarters; of fertile pinnae an inch. Length 

 of stipes of barren frond from three to four inches, and of 

 fertile frond five inches. 



Colour of frond a dull green, paler beneath. 



Aspidium podophyllum has the venation of a Polystichumy and 

 the fructification of a Lastrea.
