Only three of these fourteen species are found in the 

 United States, but one or two of the others are liable to 

 be found in Florida. 



To avoid repetition, it may be said beforehand that 

 these species were all obtained in the vicinity of Tlaco- 

 lula, province of Oaxaca, Mexico, and near Orizaba, 

 province of Vera Cruz, growing in the shadow of rocks 

 among the Sierras. Both localities lie at about the same 

 elevation, viz., 5,000 feet. They all show the effects of a 

 long drought by having their pinnae curled up or pendent. 



LIST OF SPECIES. 



1. Adiantum Capillus-Veneris L. The form of this 

 fern that is found in Oaxaca, has larger pinnules than 

 are usually found in the species, very similar to the large 

 form gathered by Prof. Lemmon in the Huachuca Moun- 

 tains, Arizona. And although collected at the same time 

 with the rest of these specimens, which all seem dry, 

 rusty and weather-worn, the fronds of A. Cap.-Veneris 

 are fresh and green, and have a few new sori growing 

 on them. This fern grew on a hillside where the soil 

 was continually moistened by the water flowing from a 

 spring. 



2. Adiantum concinnum H. B. K. Although there are 

 no full fronds of this species, there is a number of partial 

 fronds, enough to show its characteristic features. It is 

 very regularly pinnated, and the lowest pinnules overlap 

 the rachis. M. & G. have an interesting note on this 

 species, although, strange to say, they do not even men- 

 tion A. Capillus-Veneris. 



3. Asplenium parvulum M. & G. I retain this name 

 instead of resiliens Kunze for the present, because even 

 if the name was previously given to another species by 

 Hooker, it proved at length to be untenable, so I fail to 

 see why it should not hold for the species named by M. 

 & G. I have in a previous Fern Bulletin expressed an 

 opinion that A. parvulum of M. & G. was a different spe- 

 sies from any that we have in this country, and this spec-
