Caudice terete repente subterraneo nudo fibroso-radicante, 
stipitlbus sparsis solitariis squamis laxis intense fuscis lan- 
ceolato-subulatis paleaceis 4-uncias ad spithamaeam longis, 
frondibus lanceolatis acuminatis subcoriaceo-membranaceis 
spithamaeis ad pedalem 1-2-uncialibus latis profunde pinnati- 
fidis basi pinnatis apice subintegris serratisve, lobis pinnisque 
patentibiis oblongis obtusissimis integerrimis, venis remotis

Hab. Ceylon, banks of a large stream of Kotmalee Oija, elev. 
4,000 feet, Gardner^ n, 1249. I have received a specimen 
also, from Mr, ThwaiteSy but possibly from Mr. Gardner’s 
collection. 
I possess only two specimens of this distinct looking dipla- 
zioid Aspleniurriy and venture to constitute a species of it 
though it may possibly be a young form (yet in very good 
fructification) of some compound species, which time, and 
further researches only can show.
