MISCELLANEOUS NEW FERNS

ATHYRIUM RIDLEYI Copel. sp. nov. 



Filix insignis gregis A. Swartzii (Bl.) Copel.; rhachi inerme, 

 in sulcis minute pilosa; pinnis alternantibus, stipitatis, brevi- 

 falcato-acuminatis, basi truncatis, deorsum grosse crenato-ser- 

 ratis dentibus obtusis vel rotundatis, fere 40 cm longis, plusquam 

 10 cm latis; venulis 10-12 paribus, irregulariter anastomosan- 

 tibus et medio inter venas areolas plures steriles includentibus ; 

 indusio angustissimo. 



PAHANG, Ridley 18970. 



Javan ferns referable to Athyrium accedens or A. Swartzii rarely have 

 additional areolae, included between the regular rows, but are never ample 

 in a measure comparable to this fern. Digrammaria robusta Fee, treated 

 by Van Alderwerelt and Christensen as included in Diplazium proliferum, 

 was described by Fee from Bourbon material as generically distinct 

 because only the lowest veins unite. 



MICROLEPIA RIDLEYI Copel. sp. nov. 



Fronde grande, bipinnata, rhachibus sub lente minute pubes- 

 centibus ; pinnis ca. 70 cm longis, fere 20 cm latis, brevistipitatis, 

 acuminatis; pinnulis subsessilibus, basibus perobliquis, acumi- 

 natis, apicibus rectis vel subfalcatis, inciso-crenatis, costa 

 deorsum indusiisque puberulentibus, aliter glabris, membrana- 

 ceis ; lobis ca. 8 mm latis, truncatis, integris vel crenulatis ; venis 

 inconspicuis ; soris in lobo magno basale acroscopico pluribus, 

 aliter infra incisiones solitariis; indusio semicyathiforme.

Different from Microlepia platyphylla (Don) J. Sm. in texture, incon- 

 spicuous veins, hairy indusia, and most essentially in the form of the 

 indusium. Don's diagnosis of Davallia platyphylla is too brief to permit 

 certain discrimination. Hooker 2 describes D. lonchitidea Wall, as iden- 

 tical with it; his figure is that of a fern very similar to M. Ridleyi, with 

 sessile pinnules, while the text says "primary and secondary pinnules 

 much petioled." I believe that both names, platyphylla and lonchitidea,
