 stenophyllum Sod.). 



Type from Columbia, Bogota, leg. Stübel n. 4249 (HB!). 



Eudryopteris rhizomate? stipite?; lamina ovato-lanceolata, 5 dem. vel ultra 

 longa, medio 2 dem. lata, sursum in apicem breviter acuminatum sensim decre- 

 scente, versus basin gradatim et breviter attenuata (Typus II), membranacea, supra 

 ad costas venasque pilis luteo-albidis deciduis sparse instructa, marginibus densius 

 ciliatis, subtus fere glabra et eglandulosa, rachi sparse hirta, demum glabra, bipinna- 

 tifida. Pinnis inferioribus sensim abbreviatis, medialibus 10 — 12 cm. longis, IV4— 

 1^3 cm. latis, sessilibus, linearibus, a basi truncata aërophoro parvo instructa in 

 apicem acuminatum serratum sensim attenuatis ad alam 1 mm. latam pinnatifidis. 

 Laciniis usque ad 30 jugis, subrectis vel parum obliquis, obtusis vel subacutis, 

 integris, basi 3 mm. latis, sinubus latis subrotundis separatis. Venis 7—8 jugis, 

 indivisis, indistinctis. Soris majusculis, margini approximatis. Indusiis parvis, 

 glabris, mox evanescentibus. Sporangiis glabris. 



This new species in general habit resembles very much D. pachyrachis, but 

 differs from that species by its eglandulose under surface, submarginal sori and 

 somewhat hairy upper surface. Prof. Hieronymus has referred the specimen to 

 Nephrodium stenophyllum Sod., but this is, however, the true D. concinna and our 

 species is widely different from it by its pubescence and glabrous sporangia. The 

 hairs are very deciduous and the dried leaf seems without an exact examination 

 to be quite glabrous.

Type from Ecuador, leg. Sodiro (HC!). — Columbia, Lehmann n.7724 (HB). 



In size and shape of lamina re- 

 sembling D. Sprengelii, with 3—4 pair 

 of distant auricles on the strong, fur- 

 rowed stem, but it is in general more 

 nearly allied to D. pachyrachis by its 

 pinnæ tapering gradually from their 

 base with patent, short, obtuse seg- f '8- 32. D. supina (Sod.) C. Chr.
