El Porvenir (650-750 meters elevation) and camped in a coffee 
plantation along a brook, and here a rocky ravine and several 
forested hillsides yielded specimens of over fifty species not met 
with at the lower elevations; several tree-ferns, additional to the 
one previously noted were present in abundance; we were es- 
pecially pleased at securing specimens of these splendid plants, 
which will aid the study of this group by Mr. W. R. Maxon, in 
progress for “North American Flora.” A number of the forest 
trees were here found in flower, notably the ‘‘pancho” (Maye- 
paea), a relative of the northern fringe tree, its showy white 
flowers with similar narrow petals. 
The road from El Porvenir to Aguacate, traversed March 10, 
was full of interest in the vegetation of the woodlands, the high 
grassy slopes and steep hillsides, and the mountain scenery is 
superb. Here we found at about 800 meters altitude several 
kinds of plants which grow naturally at sea level in Florida, 
notably the bracken fern Pteridium caudatum; camp was made 
in a Piper thicket at 850 meters altitude and here as at other 
camps in these mountains, two blankets were needed at night 
and winter overcoats were comfortable even about the camp 
fire. Weare indebted to Sefior Castineyra for kind attention and 
useful information. Aguacate was the highest land reached dur- 
ing the trip, the barometer indicating about 950 meters on one 
hilltop. Some distance to the east the Peak of Potrerillo, the 
highest of this range, rises to the height of 3,459 feet (about 1,100 
meters) according to the sailing chart, but it is not accessible 
from the road traveled by us. 
Our last camp in the Trinidad Mountains was pitched in a 
poma rosa jungle at Arroyo Grande about 650 meters altitude; 
here we were on the southern side of the mountains and the vege- 
and a silver-palm (Coccothrinax) were seen on a rocky hillside. 
On March 12 we traveled from Arroyo Grande, down the south 
slope, to the picturesque ancient city of Trinidad, mostly through
