31-1: RECORDS. 



The vegetation, excepting in certain restricted areas, is of the 

 tropical rain-forest type. The large trees are clothed with a 

 heavy epiphytic growth chiefly composed of bromeliads, aroids, 

 orchids, ferns and a CyclaiitJicra. At the higher levels the 

 Hymenophyllaceae, Musci and Hepaticae predominate, among 

 which, however, many larger ferns and small orchids find a 

 place. Four species of tree ferns, and several species of palms 

 are to be found. Helicoiia, a plantain-like plant, is very 

 abundant at high altitudes. Lianas and *' ropes," as air roots 

 are called locally, are abundant. 



In the Grand Savannah, desert conditions prevail, caused by 

 the small rainfall (59 inches), and the shallow soil underlaid by 

 trap rock. The vegetation here, and along the rocky shores 

 is quite distinct in character. A viviparous agave and four cacti 

 are here to be found. The savannah is a sloping, grassy plain 

 with scattered shrubs and small trees among which occur several 

 Mimosoideae. 



The strand vegetation on account of the steep, gravelly char- 

 acter of the shore is meager m species. The sea-grape {Cocco- 

 lobis uviferd) is everywhere, and IpouKEa pes-caprcE and Cana- 

 valia are common. Tcrininalia occurs in some localities.
