UvERO, the Sea Grape — Cocoloha uvifera Jacq., and perhaps some 

 other species of this genus, occupying the sandy shores. 



Finally an entire new set of trees appears on the high elevations 

 somewhere above 2500 feet, a dozen or fifteen species, whose botani- 

 cal identity has not yet been determined. Here the ponderous 

 Barril, a Caesalpinia, with trunks up to 3 and 4 feet diameter, and 

 80 to 100 feet in height, and the not less developed Mulato and Re- 

 TAMA (24 inch) are the most prominent timber trees. Several small- 

 er melastomaceous species, especially a magnificent golden-leaved 

 one, Aguacate cimarron, add here to the wealth of foliage. Some 

 of the lower level species, unless they be varieties, extend their field 

 of distribution into these higher regions. Stray Cedars are found, 

 RoBLE and Ocuje are present, the ubiquitous Yagroma makes its 

 silvery show, besides Buniato, Copal, Cudya, Badano, Guayaba, 

 Guadio, Cuariduro, Jaguey, Lechero, Sangretoro, and even the 

 JucARO, which usually and preferably frequents the seashore was 

 represented by a 30-incli specimen. A number of the lower-level 

 species are recognized here as varieties, thus Copeysillo, Sabicu 

 de la Maestra, Ayua amarillo, Majagua de la Maestha, Almen- 



DRILLO. 



The ubiquitous Mui, which, as we have seen, forms generally 

 the undergrowth, has, however, vanished with the 2500 foot level. 

 Instead, tree ferns — Aurel — two species, and palms (Manaca and 

 the spiny Juta), have become quite general, as also scrubby thorns, 

 among which the ubiquitous Sarsa, Pisonia aculeata L., combin- 

 ing spikes and hooks in most effective manner is especially promin- 

 ent and annoying. Small trees of Yamagua, Jucaro, Mulato, and 

 some Melastomaceous species form the undergrowth of the moister 

 slopes, and a number of un-named shrubs make a dense tangle on 

 the drier ridges. Ferns, mosses, grasses (especially the sticky 

 Pharus latif alius) and other mesophil or xerophil herbage according 

 to location, cover the ground. On the whole, however, it is notable 

 that outside of the openings in the river valleys and seafront, the 

 lower vegetation is extremely scanty. 



There is one feature of distribution not yet mentioned wlsich is 

 of peculiar interest, namely the occurrence of just one conifer, a 

 Pine {Pinus occidentalis Sw.) of the Yellow Pine series, and very 

 pitchy indeed. This Pine is ranged by botanists with the five- 

 needled (quinae) ones, also varying to four and three needles; here, 

 Bowever, it varies even to two, and has mostly three and two needles.
