114 Nasu: Costa RICAN ORCHIDS 
south and west along the gorge of the Rio Reventazon, traversing 
the region of Juan Vifias and Santiago. It then proceeds through 
Cartago to San José, the capital of the country, beyond which 
place Mr, Maxon did not proceed by rail. With this place as his 
base, excursions were made into the neighboring country, includ- 
ing the valley of the Rio Tirivi and the estate of La Palma, a few 
miles northeast of the city. While here a visit was made to Santo 
Domingo de San Mateo, at an elevation of about 300 meters, a 
little to the westward of San José, and the only locality visited 
west of that city. Mr. Maxon reports it as an exceedingly dry 
region at the time of his visit, but without a characteristic desert 
vegetation. A number of orchids were secured here, some of 
them of exceeding interest. 
At Cartago, which has an elevation of about 1450 meters, 
considerable collecting was done, especially of living plants, of 
orchids and bromeliads. Collections were also made at Santiago, 
a few miles to the eastward of Cartago. At Turrialba, on the 
border of the Herra caliente, some time was spent, and from that 
place a trip was made to the low humid forest on the border of 
the Rio Reventazon, at an altitude of about 600 meters. While 
at Cartago an excursion was also made to Coliblanco, an estate 
lying at the base of the volcano of Turrialba. One of the princi- 
pal excurions while at Cartago was to the Finca Navarro, at an 
altitude of 1,350 meters. Navarro lies about seven miles to the 
southeast in a mountain valley a little lower than Cartago, at the 
junction of the Agua Caliente and the Rio Naranjo. Many of 
the orchids were secured at this point. 
Judging from Mr. Maxon’s collections and from recent publi- 
cations, the orchid flora of Costa Rica must be exceedingly rich. 
It is to be hoped that explorations so well begun may be continued, 
for such continuation is certain to yield valuable results, Follow- 
ing are some of the orchids secured by Mr. Maxon, which may be 
safely reported upon at present.
