220 MARATTIA LAX A. 



bipinnate, deltoid-ovate in outline, somewhat fleshy in texture, 

 of a dull dark green, paler beneath. The pinnae are opposite, 

 oblong, and from twelve to eighteen inches long. The pinnules 

 are broadly lance-shaped, acuminate, the lower ones cordate at 

 the base; the fertile ones crenate or sinuate at the edges, and 

 the sterile ones irregularly serrated: they are all remotely 

 veined. 



Sori placed near the ends of the veins in a line along each 

 edge of the pinnules, the spore-cases shortly ellipsoid, bilobed, 

 the lobes at length spreading. 



Stipites from twelve to twenty-four inches long, and scaly in 

 the lower part. 



A rare Fern, of considerable bulk, interesting in a collection, 

 but hardly to be placed among the more elegant and effective 

 species. 



For fronds I am indebted to Mr. Smith, Curator of the Royal 

 Gardens, Kew. 



It can be procured of Messrs. Veitch, of Chelsea; Rollisson, 

 of Tooting; and Sim, of Foot's Cray. 



The illustration is from Mr. Smith's frond.
