Hanc filicem nobilem, quam speciem Alsophilaj esse judico, 

 non obstante, indusio obsoleto, legi ad pedes collium Naga 

 dictorum, Martio. 12, 1836. 



Si nova species sit dicatur A. Sollyana.

I.' Pinna. 



2/2/ Lobes of pinna and sori in the dry state. 



3.' Ditto a lobe in the moist state. 



4. 5 Long section of a lobe and fructification. 



This plant belongs to the same genus as the Cyatheo-Dick- 

 sonia, from which it differs in habit in the involucrum being 

 less membranous and closed, and the pedicellate capsules, 

 which appear to fall off leaving their stalk behind. 



Sori marginales. Involucrum excertum cyathiforme margo 

 externus e margine frondis incurvata constitutus. Capsulce 

 pedicellate. Habitus Davalliae. 



Frons 1 J. pedalis 3 tenera, 1 pinnata ambitu oblongo 

 linearis, stipes albus. Pinnis confertis alternantibus pin- 

 natifidis apice lobatis lobis dentatis. 



Costis (pinnarum ultimis) inconspicuis, venulis secon- 

 dares tot quot lobis, et his respondentibus. 



Sori marginales rotundati. 



Indusium sporulis substrat. clausum membranaceum : la- 

 teri exterior, saepissime cum margine intra flexo, frondis con- 

 fluent demum centro aperiens ; margine lacerum et subbila- 

 biat. Receptaculum elevatum o, capsulese subsessiles sporula 

 lievia. 



Infra Budrinath. Mont. Himalayensium. Mr. Edgeworth. 



This Fern appears to me intermediate between Dicksonia 

 and Cyathea, or Alsophila, with the former it agrees in the 

 inflexed margin of the frond, assisting in the formation of 

 the indusium, in the subbilabiate dehiscence of this, and in 

 the venation, or rather in the sorus being terminal (on the 

 venules.)
