common vegetables and tropical fruits are grown. The pro¬ 
ducts of the settlement are shipped to Gyayaquil, Ecuador, by 
means of a small schooner which usually makes monthly trips 
to the mainland. The plateau region has several high hills and 
craters on it. 
There are no distinctly halophytic plants around the bay so 
far as was observed. The beaches here are too steep and the 
wave action at times is so strong that such plants would hardly 
be able to maintain a hold. The flat back of the beach is covered 
with Prosopis trees and bushes. 
The country is covered with low dense forests below an eleva¬ 
tion of 600 ft., which are made up mostly of trees of, Bursera 
graveolens, Piscidia Erythrina, Psidium galapageium and Zanth- 
oxylum Fagara. In many places in the forest there is a dense 
growth of bushes under the trees, which are mostly of the spe¬ 
cies usually found on the lower parts. Places occur in the for¬ 
est, however, where the trees are so closely arranged that there 
is very little undergrowth. On rocky hills and craters, in the 
lower part of this region, there is a considerable growth of Cer- 
eus galapagensis. In low places along the side of the road lead¬ 
ing to the settlement there are also low groves of Hippomane 
Mancinella trees. On the steep slopes between 600-800 ft. ele¬ 
vation there are fewer trees and more bushes than lower down. 
The bushes that are commonly found here are: Croton Scouleri 
var. grandifolius, Clerodondron molle, Lipochaeta laricifolia and 
Psychotria rufipes. In some places on these hillsides, however, 
there are small trees of Scalesia pedunculata, and Hippomane 
Mancinella, the last of which is sometimes covered with Tilland- 
sia insularis. Many of the bushes disappear higher up and those 
that remain are very much scattered. There is a heavy growth 
of grasses and sedges in this region consisting of the following 
Species: Cyperus rubiginosus, Digitaria sanguinalis, Leptoch- 
loa virgata, Panicum geminatum, Seleria pterota, Setaria setosa, 
and Stenotaphrum secundatum. Ferns which occur in shady 
protected places in this region are: Asplenium formosum, A. 
sulcatum, Doryopteris pedata, and Dryopteris furcata. The 
plateau region above 800 ft. elevation is covered in most places 
with_ grasses, the most common species of which is Paspallum 
conjugatum, while in low and protected places there are a few 
trees and bushes. In temporary pools of water, formed during 
the rainy season, such aquatic and semi aquatic plants as Azolla
