Jose, at an altitude of about 1,500 meters. I was most hospit- 

 ably entertained here for three days by Don Enrique Fernandez, 

 to whom I desire to extend my sincere thanks, as well as to Pro- 

 fessor J. F. Tristan, who accompanied us, and to both of whom 

 I am indebted for assistance rendered in other ways throughout 

 my visit. The vicinity of La Palma, like that of Coliblanco, 

 is extremely interesting for its ferns ; and the number of new 

 or unusual ferns collected indicates that much is yet to be done 



After this I spent several days at Santo Domingo de San 

 Mateo, the only locality I visited west of San Jose. This vicinity 

 (elevation about 300 meters) is exceedingly dry, and yet without 

 a characteristic desert vegetation. My collections here were 

 mainly of woody fungi and orchids — the latter, to the number 

 of about thirty, in prime condition. On this trip I was accom- 

 panied by Dr. Alfaro. 



directly south of Cartago, my final and principal other trip was 

 to Finca Navarro, recently made familiar to fern students as the 

 type locality of many of Dr. H. Christ's new species, collected 

 by Werckle. Navarro lies in a mountain valley a little lower 

 than Cartago, and about seven miles to the southeast at the con- 

 fluence of the Agua Caliente and the Rio Naranjo. The former 

 is a small river bordered by large trees from which I collected 

 many orchids, the latter a rapid stream issuing from a small 



most prolific in ferns. Besides herbarium material, about sixty 

 numbers of living plants were collected, mostly ferns, aroids and 

 orchids. Among the last were two terrestrial species found only 

 once. The three days that I was enabled to spend here, through 

 permission of the owner, Mr. George Carter, of Cartago, were 

 most productive, and I regret that in these notes I am unable to 

 touch even briefly upon the beautiful orange plantation he has 

 here established, which, through his untiring industry, bids fair 

 to prove a marked success. 



Although the season proved unfavorable for securing a large
