Aspidium gleichenioides Christ, Bull. L'Herb. Boiss. II. 4: 960. 1904. 
Dryopleris gleichenioides C. Chr. Ind. 268. 1905. 
Costa Rica, Foréts du Barba, Tonpuz nr. 1935 (C). 
In Smiths. Misc. Coll. 52: 395 I referred this to D. pterifolia, it is, however, 
a rather common form of D. rudis with the upperside nearly glabrous. 
It can scarcely be doubted that the true Nephrodium letragonum Presl. Rel. 
Haenk. 1: 85. 1825 is the same as D. rudis. Unfortunately the original specimen 
in Herb. Presl (!) 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 Scauri and GOLLMER (B), show 
that rachis and coste beneath bear several small scales. Lamina with a pair of 
reduced pinn: and 2—3 pairs of glanduliform warts. 
My new species D. Pittieri C. Chr. Smiths. Misc. Coll. 52: 393 from Colombia, 
Pirtrer nr. 1200 (W) I regard now as a very coriaceous form of D. Engelii with 
rather numerous scales along the coste 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. 6; 380. 1909; Smiths. Misc. Coll. 
52: 392 (erroneously as D. Heimeri) — Fig. 16c. 
Type from Brazil, Sao Paulo, Campinas, A. HEINER nr. 540 (Rg). 
The only Brazilian representative of the group of D. 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. 52: 395. 
Alsophila pilosa Mart. et 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 D. pterifolia and it is 
absolutely identical with Alsophila pilosa Mart. et Gal. according to authentical
