A characteristic form, which resembles nol a little D. augescens, but it is 

 thin-leaved and the rhizome and scales different. It seems to be common in Ve- 

 nezuela and similar Forms occur in the West Indies, where intermediate forms 

 between the type and the variety are to be found. Such a form is that from St. 

 Kitts, leg. Breutel, on which Presl partly founded his Lastrea scabriuscala, 

 which name I retain for a Brazilian form.

Nol essentially düTerent from var. dependens, but much larger; it differs from 

 the type by the thin texture, light colour and sparse pubescence, the upper basal 

 segment of the lower pinnæ is nearly always deeply lobed but not always very 

 prolongated; underside, especially on costæ and costules densely glandular; indusia 

 thin, flat, rather setose.

A. deversum Kze. is partly D. mollis partly this variety, which latter was de- 

 scribed by Mettenius under the name A. deversum and by him supposed to origi- 

 nate from Cuba; il was described after cultivated specimens, which I have seen 

 (B), but I have not seen a Cuban specimen resembling it, while not a few speci- 

 mens from South Brazil quite correspond with the original one. It is A. patens 

 Link, who quoted the locality: Rio de Janeiro and Raddi's plate. I also believe 

 that this form is Raddi's A. patens; Raddi says namely: "Indusiis paucis supra pi- 

 lls albidis, sed plerumque nudis". — I cannot agree with Rosenstock and Hiero- 

 NYMUS in considering this form a species distinct from D. patens; the var. scabri- 

 uscula connects it with the type. I differs mainly from true D. patens l)y its 

 almost quite glabrous leaf and indusia; the underside it rather glandulai-.
