70 WOODWARDIA. 



Sunglong liay and Chusan, Alexander. — This species is well distinguished by the 

 small size, sessile pinna.', and conipiuativcly very shallow lohes. In the two pre- 

 vious species the plnn.x are so deeply pinnatifid that the lines of sori arc quite in- 

 cluded in them ; here a very different aspect is given by the sori often stopping 

 short of the lobes, and ap|)eariiig to belong to the disc of the pinna; (almost at 

 right-angles with the costa) rather than to the lohes. All my s])ecimens turn 

 brown in drying, and both tlie fronds and involucres are more membranaceous 

 than in the preceding species. 



§§§ LoRiNSERiA, Pr. — Fronds dimorphous, fertile ones more or less conlracted, 

 in both pinnate or pinna tijid, pinnce entire or scarcely lobed, veins everyivhere 

 copiously reticulated. 



5. W. areolata, Moore; caudex rather stout creeping 

 and as well as tlie base of the elongated stipes paleaceous, 

 fronds dimorphous a span to a foot long, sterile ones subtri- 

 angular-ovate membranaceous doei)ly ])innatitid (pinnate be- 

 low), segments lG-25 lanceolate horizontally patent acute or 

 obtuse finely serrated entire or sinuato-sublobate, lowest 

 ones or pinnae petiolate, veins everywhere anastomosing, 

 fertile fronds ovato-lanceolate coriaceous pinnate, pinnce re- 

 mote linear, sori approximate occupying nearly the whole 

 under side of the pinnae between the costa and margin. —

Hab. Bogs, Massachusetts, near the coast, to Virginia and southward {A.Gray), 

 Gronovius, Michaux, Pursh, T. Drummond, Chapman, and all American bota- 

 nists ; apparently most abundant in the Southern States. — This has so much of 

 the aspect of Jfoodwardia, that I cannot but think it better to retain it as a sec- 

 tion of tliat than as a distinct genus : and I think that my next species, W. Ilar- 

 landii, naturally ranks in the same group, as to general structure and venation, 

 although the dimorphous character of the fronds is not quite so apparent. 



6. W. Harlandii, Hook. ; caudex creeping scaly as is the 

 base of the elongated stipes, fronds subdimorphous simple or 

 tripartite generally deeply pinnated or the two lowest segments 

 free broad-ovate in circumscription subcoriaceous, segments 

 3-7 inches often a span long an inch to H inch broad, terminal 

 one more elongated, those of the sterile frond broad oblong- 

 lanceolate those of the fertile frond linear oblong or lanceo-
