quite sure, although I believe that it was justified; Fee's figure represents our 

 species rather well and the specimen determined as A. eriosorum has also the 

 characteristic solitarj' setæ on the veins above and black veins. It is proliferous 

 at the base of the upper pinnæ as well as another specimen from Minas Geraes: 

 Barbacena, Excurs. Netto-Glaziou-Schwacke 21 s*/,; 1374 (HB. HC), with doubt referred 

 hereto. It has a persistent, sparsely setose indusium. Further I refer provisionally 

 hereto a specimen from Minas Geraes: Caldas, G.A.Lindberg n. 553 (HB), and pro- 

 bably also Glaziou n. 4434 (HB). Without rhizome it will be very difficult to judge, 

 if these specimens belong to D. scariosa or to D. oligocarpa (Pol. retnsum Sw.), which 

 species they resemble to the same extent, though considerably larger. 



Aspidium oligocarpum var. crassistipitatum Hieron. Engl. Jahrb. 22: 367. 1896 

 from Argentina: Siambon, Lorentz n. 156, 251 (HB) is, probably, also a form of 

 this species: it has a similar pubescence and black veins, but texture thinner and 

 stem thick, flat, fragile. Rhizome short-creeping.
