var. Rossii, n. var. 
Under the name D. Rossii I have described a Mexican fern as a new species 
after specimens collected in Morelos: Cuernavaca, Santa Maria by H. Ross nr. 279 
(Herb. Munich, CC); my description is till now not published. Comparing my 
specimen with several other specimens from Mexico I fear that my proposed new 
species cannot be distinguished specifically from the Mexican form of D. patula, 
Aspid. apertum Fée, although the typical form looks very distinct. It differs by 
the deeply cut lamina, which is distinctly glandular on both surfaces, by its very 
unequal-sided pinnz and pinnules, and especially by its narrow, toothed segments; 
under surface pale or even glaucous; stipe and rachis reddish, clothed with narrow 
scales. Indusium small, reddish. — The lamina is generally deltoid in outline, 
firm. — This is nearly exactly a D. glandulifera on an enlarged scale, — the basal 
pinne are up to 15cm. long — and it also comes near to certain forms of D. cin- 
namomea, from which it differs by its larger, deltoid lamina, pale-green underside, 
position of sori and unequal-sided pinnules.

Type from Ecuador, in valle Pastaza, Stipe nr. 848 (B). 
This I have not seen. It is certainly closely allied to JD. patula but is 
described as exindusiate.
