On March 16 we returned to Cienfuegos by the very comfort- 
able little steamer “‘Josefita”; some collecting was accomplished 
near the city on the morning of the seventeenth, and in the after- 
noon we proceeded again to Castillo de Jagua at the mouth of 
Cienfuegos Bay, which was made the base of operations for 
eleven days. The picturesque little pueblo takes its name 
from a small and beautiful fortress built some two hundre 
years ago to command the narrow entrance, and the hotel is im- 
mediately alongside of this interesting relic of Spanish ascend- 
ancy. From March 18 to 22 collections were made along the coast, 
and near it, including a visit to the valley of the Rio Arimao, 
some ten kilometers to the east, a small sailboat proving a con- 
venient means of transportation, and a satisfactory view was 
thus obtained of the coastal flora. The gigantic cactus Cereus 
nudifilorus is locally abundant and fine fruiting specimens were 
obtained, supplementing the flowering ones had last year from 
Guantanamo; two palms, one a Copernicia the other a Coc- 
cothrinax, grow plentifully at Punta Diablo and Punta Sabanilla 
on either side of the harbor entrance and at Punta Diablo another 
(Thrinax) occurs sparingly. Shrubs and small trees were found 
in great variety; the most striking floral feature was a bright 
scarlet-flowered tree of the genus Erythrina, blooming as many 
Cuban trees do before the season’s leaves appear, and so conspicu- 
ous as to be detected from the boat while more than a kilometer 
off shore at Punta Colorado, east of the lighthouse. The trip 
up the Arimao brought us in gare six kilometers, to fresh water, 
and here many aquatics were collec 
Mr. Earle joined the pa again on March 23 and we at 
once started in a cat-boat with two practicos eastward along the 
coast to study the flora of the southern foothills of the Trinidad 
Mountains and the adjacent river valleys, touching at Guajimica 
Cove, and proceeding that night as far as Rio San Juan where 
we camped on a sand-bar for two days, about half-way between 
Cienfuegos and Trinidad. There is here a delightful little harbor 
between the coastal hills; the borders of extensive mangrove 
swamps yielded specimens of many species of interest, anda small 
ravine, in the foothills, where a little stream cascades through
