257. Dryopteris Goeldii n. sp. — Fig. 43a. 
Type from Brazil: Linkes Ufer d. Parahyba, leg. GoErp: 1887 nr. 3 (C). 
Rhizomate oblique-erecto, squamis paucis stellato-ciliatis instructo. Stipitibus 
ad 30cm longis, glabris. Lamina ovata, 30—40 cm longa, 20 cm lata, pure viridi, 
firmo-herbacea, rachi minute stellato-puberula excepta glaberrima, ad insertionem 
pinnae lateralis supremae gemmulifera, pinnata cum pinna terminali subhastata. 
Pinnis 6—7-jugis, inter se 3 cm 
remotis, breviter  petiolulatis, 
lanceolatis, 10 cm longis, 1'/» cem 
latis, acuminatis, ad basin pa- 
rum attenuatis, saepe auriculatis, 
ad tertiam partem incisis. Lobis 
obliquis, acutis vel obtusiusculis. 
Venis 8—9-jugis, basalibus dua- 
bus semper anastomosantibus, 
sequentibus duabus ad sinum 
libus vel potius inframedialibus. 
Indusiis minimis, pilis bi-tri- 
furcatis ciliatis, mox evanidis. 
Sporangiis glabris. 
A critical species, in certain 
characters resembling several 
other species. It differs from D. 
tetragona by its less cut pinnze and 
glabrous coste, from D. juruen- 
sis by more pinne and not war- 
led surfaces, from D. pyramidata 
by distant pinnze, terminal pinna, 
glabrous coste and venation, 
from D. anoptera, which it re-

ture and distinctly lobed pinnz, from D. scabra by venation, glabrous frond etc. 
Still its nearest ally is D. straminea and it may be the same species and like it a 
variety of D. vivipara; it differs by its united basal veins and more numerous veins, 
more deeply cut pinnz of thinner texture and margins not so thickened.
