230 VEGETATION- 



GOVERNORS HARBOR, ELEUTHERA. 



Landing in the town on the west side of the island, the first thing of 

 interest observed was a grove of Casuarina trees under which were a great 

 number of their seedling plants. These seedlings were most abundant in 

 damp soil on the edge of a small, brackish marsh. They were the only young 

 Casuarinas that we saw during the trip. In only two other places had we 

 noticed that Casuarina had established itself uncultivated. These were on 

 New Providence, where one or two small trees were seen on the south beach 

 and near the margins of the salt marsh described in the treatment of that 

 island. 



Passing over the usual ridge through the center of the island, we found 

 on the eastern beach the best example of dunes that we met with in the Ba- 

 hamas. These dunes, the highest of which were about 40 feet above the sea, 

 are arranged in a broken series with slight depressions between them. They 

 slope landward to a low meadow of Cynodon dactyl on (L.) Kuntze (Bermuda 

 grass), which passes easily into the rocky slope of the hills behind. The 

 beach at the foot of the dunes is covered at high-tide mark by an association 

 of Uniola paniculata L., Tournefortia gnaphalodes (Jacq.) E. Br., Iva imbri- 

 cata Wait, and Cakile cequalis L'Her. Behind these is a fringe of tall Suriana 

 maritinia L. with which is mixed a little Salmca petrobioides Griseb. and 

 Cenchrus tribuloides L. Cy penis bninneus Sw., Cenchms and Salmea, to- 

 gether with scattered individuals of Agave rigida Mill., cover the seaward 

 slope of the dunes and their outer ridges are occupied by Uniola paniculata L., 

 Cypenis brunneus Sw.. and fine beds of Hytnenocallis arenicola Northrop. 

 The slight depression between the outer and inner ridges is filled with Setaria 

 glauca (L.) Scribn.. Cliloris petr&a Desv., Salm-ea petrobioides Griseb., Agave 

 rigida Mill., and HymenocaUis arenicola Northrop, which is here even more 

 abundant than on the higher places. The tops of the inner ridges are covered 

 with Cliloris pet ma Desv., Cyperus brunneus Sw., Strumpfia maritima Jacq., 

 Salmea petrobioides Griseb., Euphorbia buxifolia L., and the trailing Am- 

 brosia liispida Pursh. Urechite-s andreirsii (Chapm.) Small, here low, bushy 

 and scarcely trailing, is also rather abundant. The abrupt, landward slope 

 of the dunes is furnished with an open growth of Setaria glauca (L.) Scribn., 

 Cenchrus tribuloides L., Leptilon canadense (L.) Britton, and Malpighia 

 polytriclia Juss. The latter is here very depauperate, and not over a foot and 

 a half high. 



The growth on the western slope of the central elevation is not of the
