BROADHURST: STRUTHIOPTERIS IN NortH AMERICA 275 
Unfortunately the fertile fronds are lacking; if these Tonduz 
plants do not belong with pteropus, they should nevertheless be 
separated from polypodioides. . Without the fertile fronds it is, 
of course, impossible to place them with certainty. 
Two incomplete specimens from Costa Rica (‘‘ Foréts du Roble, 
volcan Frazu,”’ Pittier & Durand 4132, and U. S. National Herba- 
rium no. 575238, without definite locality, Wercklé) and one from 
Nicaragua (Omotepec, C. Wright) suggest the Tonduz plants in 
the breadth and texture of the lamina and in the shape of the 
pinnae; they lack the winged stipes, however.
