Dryopteris plurifolia V. A. V. R. 



Nep/irodiimi. — Caudex erectus, 20—30 cm. altus, foliis 6— 10 munitus. 

 Stipites 40—80 cm. longi, cum rhachide pallide brunnei et dense, minute 

 puberuli. Frondes ovato-lanceolatae, usque 90 cm. longae vel longiores, 

 rhachide subtus ad bases pinnarum aërophoris elevatis munita. Pinnae 

 herbaceae, supra (praesertim ad venas) setulis brevibus longisque, pallidis 

 munitae, subtus (venis exceptis) giabrae, lineari-lanceolatae, sessiies, acu- 

 minatae, infimae non-reductae maximae, 17'/2— 25 cm. longae, 2— 3'/2 cm. 

 latae, profunde pinnatifidae, basin versus angustatae; pinnae stériles longis- 

 simae latissimaeque, approximatae, segmentis confertis; pinnae fertiles 

 brevissimae angustissimaeque, segmentis + remotae; pinnae reductae 

 remotae, fere usque ad basin stipitum productae, superiores auriculiformes, 

 inferiores sensim glanduliformes; costa supra setulis brevibus longisque, 

 pallidis, acutis copiose hirsuta, subtus (cum costulis venisque) dense, pallide 

 appresso-pubescens. Segmenta patentia, lineari-oblonga, levissime falcata, 

 integerrima, appresso-ciliolata, obtusa ; segmenta sterilia usque 15 mm. longa, 

 5 mm. lata, basi paullo dilatata; segmenta fertilia usque 9 mm. longa, 

 2'/2 mm. lata, basi distinctius dilatata; venae in segmentis maximis 11 — 13 

 utrinque, ascendentes, simplices, hinc inde furcatae, infimae tantum ana- 

 stomosantes. Sori ad venas omnes mediani, contigui inferiores divaricati; 

 indusium in juventute conspicue purpureo-brunneum, parce puberulum. 



Near D. heferocarpa O. Ktze, which, however, has both barren and 

 fertile pinnae equal or nearly equal in size, placed on slight increasings of 

 the rhachis but without aërophores at the base, and the indusium seemingly 

 not purplish vi'hen young.
