io6 Ferns of British India and Ceylon. 



less covered with sori, pinnae articulated. Rhizome 50 feet long ; 

 wide-creeping over trees. 



This genus is allied to Stenochlaena, and like that often 

 has the rachis winged, and is liable to variations of abnormal 

 sterile growth ; it differs in its venation, which is that of 

 Neurocallis and Acrostichum, genera widely differing other- 

 wise in their short erect rhizomes and adherent pinnae. The name 

 was given by J. Smith on the supposition that the sori were 

 always marginal and linear, as the specimens he worked with 

 had only semi-contracted fertile fronds seeding along the margins 

 (a variation so common in all the ferns of this tribe), though the 

 normal state of the fertile frond is to be entirely covered with 

 seed on the under side. 



Lomagramma lomarioides, (Bl. under Leptochilus ; Hook, 

 under Acrostichum.) Rhizome strong, wide-creeping, and epiphytic 

 on trees covered with a deciduous spongy indumentum, stipes 6-8 

 inches long, deciduously scaly ; fronds up to 3 feet long by 1 foot 

 or rather more broad, with numerous sessile, articulated pinnae, 

 the sterile ones 1 inch broad, the apex acuminate, "the margin 

 with distant, shallow, rather falcate serratures, more prominent 

 towards the apex, the base generally rounded ; texture very thin, 

 membranaceous, transparent, pellucid-dotted, the rachis and 

 costa beneath scaly, the former more or less winged, particularly 

 towards the apex ; veins prominent and raised on both sides, 

 fertile pinnae J inch broad, normally soriferous over the whole 

 of the under surface, but sometimes only partially contracted and 

 soriferous. Hook. Syn. Fil. p. 423. Leptochilus lomarioides
