southern portion of the island. The forest is dense and contains 

 many vines and epiphytes. 



On the hills and ridges near Nueva Gerona this forest is characterized 

 by the large-trunked Bomhax emarginata, the cabbage-palm {Sabal 

 parviflora), Casearia sylvestris, Trichilia hirta, Amyris balsamifera, 

 Cordia glohosa, etc. On open exposed knobs and cliffs Agave papyro- 

 car pa, and Plumiera emarginata become conspicuous. 



The forest on the limestone plain of the "South Coast" is quite 

 similar but with a larger proportion of leguminous plants. Here 

 occur Bauhinia, Lysiloma hahamense, etc., and towards the interior, 

 especially where burned or where lumbered, there are areas which 

 may be termed "chaparral." 



14. The Chaparral Formation. 



This formation, as exemplified near Hato, in the interior of the 

 peninsula between Bogarona and Caleta Grande, is a dry forest of 

 small -leaved trees of low stature, and with a rather large proportion 

 of thorny species. Here occur Bucida Buceras, Tecoma pentaphylla, 

 Pithecolohium arboreum, Lysiloma bahamense, Ouratea agrophylla, etc. 



15. The Sea-cliff Formation. 



Wherever the mountains or the limestone plains form a cliff along 

 the coast, there appears a very characteristic fringe composed of a 

 palm, Thrinax Wendlandiana, and the peculiar clubby, branched 

 Apocynaceous plant, Plumiera emarginata, accompanied by a number 

 of other less conspicuous species, these constituting altogether what 

 may be termed the Sea-cliff Formation. Good examples of this 

 vegetation are to be seen along the steeper seaward slopes and cliffs 

 of the Colombo and Bibijagua mountains. 



Owing to the brief time spent in the Isle of Pines no attempt was 

 made to study the marine formations along the coasts, although the 

 few observations which were made indicated a rich flora.
