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 (" Forests du Roble, 

 volcan Frazu," Pittier & Durand 4132, and U. S. National Herba- 

 rium no. 575238, without definite locality, Werckle) 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.

Plants terrestial. Rhizome more or less inclined, apparently 

 short, 7 mm. to 2 cm. thick, the scales lanceolate, 5-10 mm. long, 

 chestnut to maroon or brown, darker and thicker toward their 

 base. Sterile fronds 20-70 cm. long, of two types: (1) clustered, 

 shorter, spreading, coriaceous or rigid-herbaceous ones with very 

 short stipes and close pinnae, and (2) from the center of those 

 just described, taller, more or less erect, herbaceous fronds with 

 long stipes, much longer pinnae, and wider sinuses; stipes clus- 

 tered at the apex of the rhizome, 3-27 cm. long, somewhat or not at 

 all angulate, without vestigial pinnae, variously colored, reddish 

 brown, yellowish brown, or purplish chestnut, but not bicolored; 

 lamina 21-60 cm. long, 2-9 cm. wide, narrowly elliptical to linear, 

 very gradually reduced at the base (type G), and gradually re- 

 duced at the apex, the pinnae often opposite near the middle or 

 the base of the frond; pinnae 36-80-jugate, oblong-linear to linear- 

 falcate, the apex rounded-acute, the base prominently dilated in
