In the months of April and May, 1906, Mr. William R. 
Maxon, of the U. S. National Museum, during a furlough from 
that institution, made, in the interests of the New York Botanical 
Garden, an exploration of portions of Costa Rica. Much atten- 
tion was given to the collection of living plants, especially in the 
families Cactaceae, Orchidaceae, and Bromeliaceae, which furnished 
Many specimens of great interest. The material was carefully 
Collected and excellently packed, so that little harm came to it 
during the long journey, and it arrived in fine condition. 
The orchids were especially well represented. Of many of 
these no herbarium material was secured, as at the time of col-

object of this and succeeding articles to report upon them. 
Ar, on gave, in the form of a report to the Director-in- 
chief of the Garden, an account of his explorations and many of 
the Places visited by him, in the Journal of the New York Botan- 
teal Garden for August, 1906. As this may be inaccessible to 
many, the locations of some of the places referred to, which do 
not appear in the atlases ordinarily at hand, are given here, extracted

Westerly direction through the low lands of Siquirres,.and then
