238 VEGETATION 



Guaiacum sanctum L. (Lignum vitte), IS feet liigii; also a species of fig, 

 Metopium metopiuin (L.) Small (Poison-wood), Gymnanthes liicida Sw. 

 (Crab-wood), Botirreria liavanensis (L.) Miers (Strong-back), Coccolohis 

 laurifolia Jacq. (Pigeon plum), Ichthyomethia piscipula (L.) Hitch. (Dog- 

 wood), Bursera simaruba (L.) Sarg. (Gum-elenii), Acacia choriophylla 

 Benth., Tecoma hahamensis Northrop, Thouinia discolor Griseb., Citharexy- 

 luni qiiadrangulare Jacq., Chiococca parvifolia Willd., Bumelia microphylla 

 Griseb. (Ink-berr}'), Lantanas, Cajanus cajan (L.) Millsp., with the vines 

 Smilax beyrichii Kunth, and Serjania suhdentata (Juss.) Poir. Here also 

 grew Thrinax hahamensis Cook (Goat palm) in more or less abundance. On 

 a small cay in the large central lake was a magnificent grove of Rhizophora 

 mangle L., which reached a height of 30 feet. In its branches the black 

 cormorants were building in great number. 



The large central lake is bounded on the west by anotlier high and 

 broader ridge. Its covering is very much like that of the other ridge just 

 described. The columnar Pilocereus lanuginosa Eumpl. occurred here, as 

 did also Opuntia tuna Mill. From the western base of this ridge there 

 extends another rocky Conocarpus-flat like that already described, which is 

 bounded eastward by a third salt lake. In the Conocarpus-flat, near the lake, 

 was growing a good deal of Vanilla articulata Northrop, climbing up into the 

 Conocarpus. On the sandy shore grew manchineel again, with the goat 

 palm and Conocarpus. 



About one-half mile north of Cockburn Town there are along the beach 

 some low sand dunes where Coccothrinax jucunda Sarg. (Silver palm) is 

 abundant. The gentle, landward slope of these dunes supports a low, scrubby 

 growth of such typical sand-growing plants as Solanum hahamense L., Tur- 

 nera ulmifolia L. (here called "Buttercup"), Pluclica fce.tida (L.) B. S. P., 

 BaccJiaris dioica Vahl., Petitia pceppigii Schan., Ernodea Uttoralis Sw., Genipa 

 clusiifolia (Jacq.) Griseb., Phyllanthus epiphyllanthus Jj. (Hard-head), Pi^/ie- 

 colohium heyense Britton (Eam's horn). Cassia species, Eugenia confusa DC. 

 (Stopper), with the vines E/ia&^af/r/7ia hi/Iora (Jacq.) ]\Iill., Urechites andrew- 

 sii (Chapm.) Small, Smilax beyrichii Kunth, Jacquemontia jamaicensis 

 (Jacq.) Hall, species of Passifora. and the trailing, parasitic Cassytha. 

 Chloris petrcea Desv., Setaria glauca (L.) Scribn., and Cenchrus trihulgides 

 L. were the principal grasses here. As this slope approaches the fresh-water 

 marsh, there appeared distinct associations, almost pure, in series as follows : 

 (1) Pluclica odoraia (L.) Cass.; (2) Lippia species; (3) Cladium effusuni
