366 Broadhurst: Struthiopteris in North America 



Chiuautla, Mexico. In his description, Liebmann attributes this 

 species also to Puebla and Oaxaca, Mexico. 



Distribution: Mexico and Guatemala. 



Specimens included: Mexico: Oaxaca, "Santa Ines del 

 Monte, Zimatlan-Oaxaca Mts.," altitude 3,000 m., Conzatti ijij 

 (N). Oaxaca, "Cerro de San Felipe," Conzatti and Gonzalez 52Q, 

 altitude 3,000 m. (N). Guatemala: Dept. Chimaltenango, 

 Volcano Acatenango, altitude 8,500 ft., Kellerman 6481 (N). 



Liebmann described L. falciformis without seeing the fertile 

 leaf; he probably had a young specimen, for a single pinna of the 

 cotype from Berlin measures 14 cm., and he gives the length of the 

 pinnae as 10 cm. (4 in.). Liebmann speaks of the pinnae as sessile, 

 meaning, apparently, compared with his L. spectabilis, for a single 

 sterile frond (U. S. National Museum no. 474921) determined by 

 Liebmann has distinctly petioled lower pinnae. The specimen is 

 apparently very immature. It differs, however, from Liebmann's 

 description in having rounded rather than "obliquely cuneate 

 cordate" bases, elsewhere described by him as unequally angled 

 cordate; the margin of this specimen is not fully serrate and is but 

 slightly cartilaginous. Notwithstanding these inconsistencies, the 

 very peculiar margin (which does fit the fragment of Liebmann's 

 Berlin specimen) makes it possible to place in this species the 

 plants mentioned above. The Kellerman plant has straighter and 

 proportionately narrower pinnae than the Berlin fragment; it 

 differs still more in this respect from the other specimens included 

 above. More material might make possible its separation. 



A plant recently collected in Panama, in "moist ravines above 

 El Potrero camp, Chiriqui Volcano, altitude 2890-3025 m.," Maxon 

 5335 > m ay belong here. The texture is much heavier and the 

 pinnae are shorter and broader than in the other specimens placed 

 in this species; the margin is not quite like that of S. falciformis.
