Asplenium (Diplazium) Zeylanicum, Hook. 



Caudice terete repente subterraneo nudo fibroso-radicante, 

 stipitibus sparsis solitariis squamis laxis intense fuscis lan- 

 ceolato-subulatis paleaceia 4-uncias ad spithamasam longis, 

 frondibus lanceolatis acuminatis subcoriaceo-membranaceis 

 spithamseis ad pedalem 1-2-uncialibus latis profunde pinnati- 

 fidis basi pinnatis apice subintegris serratisve, lobis pinnisque 

 patentibus oblongis obtusissimis integerrimis, venis remotis 

 furcatis, soris linearibus, involucris venula basi superiore 

 loborum prascipue diplazioideis. 



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. Thwaites, but possibly from Mr. Gardner's 

 collection. 



I possess only two specimens of this distinct looking dipla- 

 zioid Asplenium, 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.
