other country beside Mexico, and Karwinski and Gale- 

 otti obtained their specimens in the province of Oaxaca, 

 very likely near where my specimens came from. M. & 

 G. listed it under Kunze's name, as Allosorus Karwinskii, 

 which was not bestowed upon it until 1839. But La- 

 gasca had recognized it as a distinct genus in 1816, and 

 when Hooker compiled his " Species Filicum " he re- 

 stored it to its rightful author. John Smith, and M. Fee 

 meanwhile had each given it a separate generic name, 

 and Smith indicated its resemblance to Osmunda by 

 naming it Ceratodactylis osmundioides. 



8. N otholccna Peruviana Desv. Notholcena squa- 

 mosa (Gill) Baker. Inasmuch as Mr. G. brought only 

 two partial fronds of this species, not very much can be 

 said about it, as I did not have it before. I have, how- 

 ever, a fine plant of N. brachypus (Kze.) J. Sm. gath- 

 ered in Mexico by C. C. Pringle, and that is placed by 

 Baker under his squamosa as a synonym, while J. Smith 

 turns them about and makes squamosa a synonym for 

 brachypus. Hooker's " Species " makes it a Chcilanthcs, 

 so there is plenty of diversity in the case. M. & G. do not 

 seem to know it. If I am right about this, and the speci- 

 mens, although apparently young and much enrolled as 

 yet, agree well with the description of squamosa, it is 

 quite a different thing from brachypus, having a longer 

 stipes and smaller, beautifully fringed scales. 



9. Pellaea cordata J. Smith. A single small frond rep- 

 resents this species. Hooker in the " Species Filicum " 

 separates P. Hcxuosa Link, from cordata, but Baker in 

 the "Synopsis" combines the two, making Hexuosa a 

 sub-species. In my frond the main rachis is nearly as 

 flexuose as in Hexuosa itself, but the costse are not at all 

 so. Besides, the pinnules are much smaller, much more 

 rolled together, and all point downward. All the rachises 

 are peach-colored, and the secondary ones are glandu- 

 loso-pubescent. 



10. Phlebodium aureum (L.) R. Br. This is the same 

 small form that we have in Florida, with sori only 

 i-serial.
