Underwood: The Genus Phanerofiilebia 



8. Phanerophlebia Guatemalensis sp. nov. 



Rootstock unknown : stipes pale brownish, smooth : pinnae 

 20 X 3.5 cm., tapering at the apex, acute at base, with spinulose mar- 

 gins ; veins free, prominent beneath in drying, four or more often 

 five-forked: sori small, 1.2 mm. wide, mostly flattish In usually 

 four rows either side the midvein, about equally distributed over 

 the entire width of the pinnae : Indusium small, withering. 



Guatemala : San Miguel Uspantan, Depart. Quiche, alt. 7000. 



J. Donnell Smith, 3241 (G, N, P). 



The specimen under this number In the Columbia Herbarium 

 may be this species but more likely Is something else. The plant 

 is younger, the pinnae are smaller, the rachis is scaly, and its habit 

 is quite different. There is a second Guatemalan plant In the Gray 

 herbarium, collected by O. Salvin, that belongs here, as does an- 

 other of the same collection at Kew. A tip of another specimen at 

 Kew collected by Skinner Is probably the same, although the pin- 

 nae are larger (27x4 cm.). The species finds its nearest_a11iance 

 with P. inacrosora but Is abundantly distinct. 



The geographic distribution of the known species maybe com- 

 pared more readily from the following map, In which the numbers 

 of the stations correspond to the serial numbers of the .species.
