Maxon : Notes on NortH AMERICAN PHANEROPHLEBIA 25 
The Coban plants, which are only partially fertile and are 
aberrant in the position of the sori, were listed* incorrectly by the 
writer as P. remotispora. 
2. PHANEROPHLEBIA PUMILA (Mart. & Gal.) Fée. 
Of this species only the following material has been seen by 
the writer: 
Mexico: Top of the Sierra Madre, near Chilpancingo, 
Guerrero, E. W. Nelson 2222 (2 sheets). 
3. PHANEROPHLEBIA REMOTISPORA Fourn. 
There are in the National Herbarium three sheets of specimens 
of this species from the vicinity of Cordoba, Vera Cruz, collected 
by Hugo Fink, 1889-1891, no. 60, and not listed by Dr. Under- 
wood. Two of these respresent fertile fronds which appear quite 
typical; the third is of a plant with four fronds (30 to 50 cm. high), 
three of which are sterile, the fourth partially fertile and showing 
the true characters of the species in the position of its sori. The 
rhizome, which is not very complete, appears to have been short 
and nearly erect; it is clothed with thin delicate pale brown laxly 
ciliate-fibrillose scales of oblong-ovate form. A few scales of 
similar character occur sparingly upon the lower part of the stipe, 
and mixed with them are others that are nearly capillary and of 
a rusty color. These last extend along the stipe and rachis 
throughout, but are readily abraded. The pinnae of this young 
and nearly sterile plant are narrowly ovate or oblong-ovate, 10 
to 12 cm. long, 2.5 to 3 cm. broad (3.5 in one pinna), strongly 
falcate, long-acuminate and caudate. The margins are conspicu- 
ously long-spinulose nearly or quite to the base of the pinna (the 
spines very oblique or appressed), in this respect differing widely 
from P. juglandifolia. 
An additional specimen is: 
Mexico: Orizaba, altitude 4,000 ft., Aug. 26, 1891, Henry E. 
Seaton 49; distributed as Hemitelia sp. 
4. PHANEROPHLEBIA NOBILIS (Schlecht.) Fée. 
A species readily distinguished by the characters noted in the 
key. The margins are, naturally, more freely spinulose in the
