BOTANICAL EXPLORATION IN THE MOUNTAINS 
F NORTHEASTERN CUBA. 
Dr. N. L. Britron, DrrEcTor-INn-CHIEF. 
Sir: Having completed my work of exploration on the cays 
of the north coast of the Province of Camaguey,* I went to 
Holguin, Oriente, at the invitation of Mr. and Mrs. Angus Camp- 
bell, of the Holguin Fruit Company, to join them in their Thanks- 
giving dinner. From here I made several excursions into the 
adjoining palm barrens and low mountain sides to obtain photo- 
graphs of the peculiar mountain palm, collected in this vicinity 
the previous season, and also to secure flowers and fruits of a 
columnar Cereus. In the latter I was unsuccessful. While en- 
deavoring to set up my camera in order to photograph a colony 
of the mountain palm, I discovered a very small Memillaria 
which was barely protruding through the layer of broken stone 
that filled the interstices between the langer rocks. The largest 
of these plants were scarcely an inch in diameter, one of them 
bearing a small, yellowish flower. This cactus is evidently very 
search by Mr. Campbell and myself. As no species of Mamil- 
laria has been reported from the northern side of Cuba, and as 
it is very distinct from the one you collected on the south side 
of this province the previous winter, it will probably prove to 
be a species new to science. A number of other plants not seen 
on my last trip were also found. 
Arriving at Felton December 1, I found that Mr. Jennings S. 
Cox, Jr., general manager of the Spanish-American Iron Com-
