A characteristic form, which resembles not 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 Presi partly founded his Lasírea scabriuscula, 
which name I retain for a Brazilian form.

Not essentially different 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 pinnz is nearly always deeply lobed but not always very 
prolongated; underside, especially on costze 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; it 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 Rapprs plate. I also believe 
that this form is RApprs A. patens; Rappti says namely: *Indusiis paucis supra pi- 
lis albidis, sed plerumque nudis". — I cannot agree with RosENsrock and HriEno- 
NYMUS in considering this form a species distinct from JD. palens; the var. scabri- 
uscula connects it with the type. I differs mainly from true D. patens by its 
almost quite glabrous leaf and indusia; the underside it rather glandular.
