The present paper is the first of 2 treating of the North Ame- 

 rican representatives of the genus usually known as Lomaria Willd., 

 but to which the name Struthiopteris (Hall.) Scop. is here applied. 

 The nomenclatorial history of the genus is traced in some detail, 

 after which is given a discussion of the variable characters of its 

 members from tne systematic Standpoint. The species are associated 

 in 2 groups, the first having the pinnae adnate (never petiolate), 

 the second having the pinnae (or at least the lower ones) distinctly 

 petiolate. With these characters are associated other differences, 

 which go to make the groups fairl}'- distinct ones. Only the non- 

 petiolate species, 9 in number, are treated in this instalment. All 

 these are fulh^ described, with mention of type locality, ränge, 

 plates. and specimens examined. and an elaborate key is provided. 

 The following are described as new: Struthiopteris Maxoni Broadh., 

 from Panama and Costa Rica, the t3'-pe being Maxon 5415 

 from the mountains of Chiriqui, Panama; and 5. jauiaiceiisis 

 Broadh.. from Jamaica, the type being Harris 10099. The fol- 

 lowing new combinations are also published: Struthiopteris exaltata 

 (Fee) Broadh. {Lomaria exaltata Fee); 5. L' Herminieri (Boryi Broadh. 

 {L. L' Herminieri Bory); and 5. stolonifera (Mett.) Broadh. [Blechmtrn 

 stolofiiferum Mett.). The two new species are illusti-ated. Maxon.
