ie 
otherwise glabrous. — It may be specifically different, but having seen no perfect 
leaf I prefer to place it under D. connexa as a variety, with which it agrees fairly 
well in most characters.

Obs. Curist has described another species from Paraguay, Phegopteris subsimilis 
(. c. p. 36) = Dryopteris paraguayensis C. Chr., Ind. 282 (BaLansa no. 304), which I 
have not seen. It is, however, scarcely a species of Dryopteris as the author says: 
Stipite basei aculeis nonnullis armato, which certainly is never found in any species 
of Dryopteris. It is probably a species of Alsophila. 
337. Dryopteris umbrina n. sp. 
Type from Brazil: SAo Paulo, BrapE no. 6532 (R!). 
Species austrobrasiliensis D. vastae subsimilis, multisquamosa, sicca atroviridis, 
herbacea. Stipite rachi costisque fuscis, squamis lanceolatis, umbrinis, basalibus 
dentatis, superioribus integris ubique subdense onustis, et breviter puberulis. Lamina 
supra praeter costas costulasque dense et venis sparsim pilis albidis strigosas 
glabra, subtus ad costas costulasque breviter et dense puberula, ad parenchyma 
venasque subglabra, minute glandulosa. Soris parvis, parum supramedialibus, ex- 
indusiatis. Divisione laminae et forma segmentorum D. subincisae similis. 
This new species may easily be distinguished from all other South-Brazilian 
species of this group by its dark-green, herbaceous leaf and numerous scales on 
stipe, rachis and cost, it resembles more some of the andine species by several 
characters which are here all united in the same species while they are separated 
in the andine species. D. squamosissima and D. mollicoma have similar scaly stipe 
and rachis but the pubescence is different. D. vasta has the rachis and coste beneath 
similarly puberulous, but it has much fewer scales and both surfaces finely downy. 
D. spectabilis is much firmer and has long hairs. D. andicola that is indusiate, and 
D. atrogrisea, resemble our species very much in colour and cutting, but their 
scales and pubescence are different. As is the case in the two last-named species 
the basal posterior segment of an upper pinnula of D. umbrina is nearly separated 
from the costule and broadly adnate to the costa from which its midvein springs 
out rather distant (2 mm) from the base of the costula. 
D. umbrina is a middle-sized species. The accepted type-specimen which is the 
largest seen, has the middle pinnz 35 cm long, but most other species are smaller 
with the ovate lamina 50—60 cm long. In shape and size of the tertiary segments 
it scarcely differs from D. subincisa and D. vasta and also D. Blanchetiana. — The 
species has probably been united with D. subincisa by most authors.
