Aspidium gleichenioides Christ, Hull. L'Herb. Boiss. II. 4: 960. 1904. 



Dryopieris gleichenioides C. Chr. Ind. 268. 1905. 



Costa Rica, Forêts du Barba, Tonduz nr. 1935 (C). 



In Smiths. Misc. Coll. 02: 395 I referred this to D. pterifolia, it is, however, 

 a rather common form of D. rudis with the upperside nearlj' glabrous. 



It can scarcely be doubled that the true Nephrodium tetragonum Presl. Rel. 

 Haenk. 1; 85. 1825 is the same as D. rudis. Unfortunately the original specimen 

 in Herb. Pres! (!) is very defective and it may belong to another related species. 



155. D. Engelii Hieron. ; C. Chr. Revision nr. 74. 



Area: Venezuela. Colombia. 



Additional specimens from Venezuela, Funck et Schlim and Gollmer (B), show 

 that rachis and costæ beneath bear several small scales. Lamina with a pair of 

 reduced pinnæ and 2 — 3 pairs of glanduliforra warts. 



My new species D. Pittieri C. Chr. Smiths. Misc. Coll. 53: 393 from Colombia, 

 PiTTiER nr. 1200 (W) I regard now as a very coriaceous form of D. Engelii with 

 rather numerous scales along the costæ beneath. 



156. Dryopteris peruviana Rosenstock, Fedde, Repert. 7 : 298. 1909. 

 Type from Peru, Cerro de Campana, Spruce nr. 4655 (RB!). 

 Very like D. rudis in habit, size and pubescence, different by setose sporangia. 



157. Dryopteris Heineri C. Chr., Fedde, Repert. «; 380. 1909; Smiths. Misc. Coll. 

 53: 392 (erroneously as D. Heimeri). — Fig. 16 c. 



Type from Brazil, Sao Paulo, Campinas, A. Heiner nr. 540 (Rg). 



The only Brazilian representative of the group of Ü. rudis and a very distinct 

 species with setose sporangia. 



158. D. strigifera Hieron.; C. Chr. Revision nr. 76. 

 Area: Colombia. 



159. D. Brausei Hieron.; C. Chr. Revision nr. 77. 

 Area: Colombia. 



160. Dryopteris piloso-hispida (Hook.) C. Chr. comb. nov. 

 Syn. Nephrodium piloso-hispidium Hook. spec. fil. 4: 105. 1862. 



Dryopteris pterifolia (Mett.) O. Ktze.; C. Chr. Revision nr. 78 fig. 49 with 



synonymy; Smiths. Misc. Coll. 53: 395. 

 Alsophila pilosa Mart, el Gal. Mém. Foug. Mex. 78 tab. 22. 1842. 

 Area: Mexico along Andes to Bolivia. 



The original specimen of N. piloso-hispidum Hook, from Ecuador, Spruce 

 sine num. (Kew!) is exactly what I previously have named Ü. pterifolia and it is 

 absolutely identical with Alsophila pilosa Marl, el Gal. according to authenlical
