cause of the war it was not possible to get the comprehensive material of the U. S. 
National Herbarium, and the material at hand is not sufficient for a monographic 
study of the species such as I have carried out in the other subgenera. There are 
probably several other species besides the 13 enumerated. Two new combinations 
of name have been published since the publication of the first part: 
237. Dryopteris membranacea (Mett.) C. Chr. Ind. Suppl. 35. 1913. 
Syn. Phegopteris membranacea Mett. Fil. Lechl. II, 22. 1859.

Subgenus VII. Eudryopteris C. Chr. 
In the first part of this monograph I have dealt with all the known species 
from tropical America belonging to this subgenus. Out of the 11 species mentioned 
the seven (one of which must be excluded) have a bipinnate-quadripinnatifid lamina. 
These species can always and easily be distinguished from other decompound spe- 
cies by 1) the decurrent midribs of the ultimate pinnules or segments, 2) the ab- 
scence of simple or articulated hairs, also along the costz and costulz above, and 
3) the large, reniform and generally persistent indusia. In general structure the 
order of pinnz and pinnule is rather lax; commonly the basal secondary pinnz 
of the middle pinnz are nearly opposite. The basal pair of pinne is rarely much 
the largest, more commonly a little shorter than the second pair, the lamina becom- 
ing ovate in general outline, and their lower pinnulz are seldom much produced, 
in several species not at all. ee 
To my former treatment I have only a few corrections and additions to 
make here. 
248. D. paleacea (Sw.) C. Chr. 
I have now seen a fragment of the type-specimen in S. The species was re- 
cently recollected in Sto. Domingo by v. TéRcKHEIM nr. 3583 (B). 
- 957. D. mexicana (Pr.) C. Chr. : 
Additional synonym: Dryopteris patula var. Morelie Christ in Lecomte, : Nol. 
syst. 1: 234. 1910. — Cerro Azul pr. Morelia, ARSENE nr. 5167 (CC, RB); Rosen- 
stock, Fil. mex. exs. nr. 3 (Rg).
