BROADHURST: STRUTHIOPTERIS IN NorRTH AMERICA 385 
found the material too incomplete to name satisfactorily. With 
this might be placed another fragment (one pinna) from Costa 
Rica, Hoffman 36. 
5. Two sheets from Guatemala, Cook & Griggs 161 and 578, 
near the Finca Sepacuite, Alta Verapaz (N); the long terminal 
pinnae suggest the smaller forms of S. Schiedeana, but they are 
heavier in texture and the bases of the pinnae are subcordate to 
cordate. 
6. Two sheets (fragments) from St. Vincent, H. H. & G. W. 
Smith 1023 (Y). Their coloring, their flattened, shining costae, 
which resemble those of SS. Underwoodiana, and their falcate 
pinnae distinguish them from S. striata, which they otherwise sug- 
gest. They are not at all like the deeply cordate, coriaceous 
specimen from St. Vincent discussed under S. striata.
