is entire or slightly toothed, and they terminate in a tapering point. The 

 sori (spore masses) are oblong in form, and consist of from eight to fifteen 

 capsules to each pinnule : they are disposed near the edge, where they form 

 a broad, marginal, and laterally continuous row. — Hooker, Synopsis Filicum, 

 p. 440. Nicholson, Dictionary of Gardening, i., p. 78. Lowe, Ferns British 

 and Exotic, viii., t. 75. Beddome, Ferns of Southern India, t. 78. 



The considerable range of variation existing in the texture of the fronds 

 of Angiopteris, and also of the more or less close disposition of the veins and 

 of the sori (spore masses), as well as the variable number of the capsules of 

 which the latter are composed, are so many characters which have induced 

 some authors to determine numerous forms as distinct species. It is thus 

 that, besides Miquel's A. angustata, from Java ; A. Arnottiana, from India ; 

 Brackenridge's A. attenuata, from the Society Islands ; Wallich's A. crassipes, 

 from India ; Desvaux's A. indica, also from India ; Hooker's A. longifolia, from 

 the Society Islands ; A. magnifica, from Ceylon ; Kunze's A.pruinosa, from Java, 

 and A. Willinkii, from Java, Presl defines as distinct species the following :
