384 BROADHURST: STRUTHIOPTERIS IN NORTH AMERICA 
except a few specimens from Guatemala there is very little from 
the region between Costa Rica and Mexico. Seven of the above 
twenty-five species have Costa Rica or Panama as type locality; 
for none of these, however, have we a sufficient number of speci- 
mens to be sure that our descriptions indicate the variation that 
might reasonably be expected. Much that we have is worth little 
because of its fragmentary condition; several of the specimens 
given under INQUIRENDAE are from this region. 
The collections recently made by J. A. Shafer indicate that 
Cuba offers similar rewards and difficulties. 
INQUIRENDAE* 
1. One sheet from Costa Rica, Pittier 1921, ‘‘Foréts du Barba, 
versant Pacifique,” 2,500-2,700 m., 1890 (N), with broad elliptical 
pinnae a little like S. rufa in shape, but differing in size, coloring, 
and in the serrate margin with definitely marked vein apices. 
A young specimen, U.S. National Museum no. 834094 (“Volcan 
de Poas, Alfaro, San José,” Costa Rica, altitude 2,300 m., 1902), 
may belong with this. 
2. One sheet from Costa Rica collected by J. J. Cooper, U: 5. 
National Museum no. 154303, November 1886; the slender, fertile 
pinnae are 25-28 cm. long, and the sori are continued on the 
dilated, non-petioled, decurrent bases of the pinnae. No petioled 
species has such fertile fronds. 
3. One sheet from Costa Rica collected by Wercklé 1901-1905; 
(the specimen is an unnumbered one from Christ’s herbarium and 
bears the name Lomaria procera, below which is written Lyst.): 
The fibrillose midribs and rachis separate it from S. costaricensts, 
S. lineata, and S. striata, to which it is nearest. The fertile leal 
is lacking, though I strongly suspect it is the one mounted with 
the sterile frond on the U. S. National Museum sheet no. 575259: 
4. One sheet (part of a sterile leaf) from Costa Rica, collected 
by Wercklé, U. S. National Museum no. 575249; is wrongly 
labeled B. Werckleana; it differs from the description and Christ $ 
, other specimens in texture, color, proportion, the margin, the ag 
of the pinnae, and in size. A pinna was sent to Christ, but 
scussed in
