common vegetables and tropical fruits are grown. The pro- 

 ducts of the settlement are shipped to Gyaya<iuil, 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- 

 oxyluni 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, liowever, where the trees are so closely arranged that there 

 is very little undergi'owth. 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 

 Maiicinella 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 moUe, 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 heavv' growth 

 of grasses and sedges in this region consisting of the following 

 species: Cyperus rubiginosus, Digitaria sanguinalis, Leptoeh- 

 loa virgata, Panicum geminatum, Scleria 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 semiaquatic plants as Azolla
