238 VEGETATION 



Guaiacum sanctum L. (Lignum vitse), 18 feet high; also a species of fig, 

 Metopium metopium (L.) Small (Poison-wood), Gymnanthes lucida Sw. 

 (Crab-wood), Bourreria havanensis (L.) Miers (Strong-back), CoccoloUs 

 laurifolia Jacq. (Pigeon plnm), IcMliyometUa pisdpula, (L.) Hitch. (Dog- 

 wood), Bursera simarula (L.) Sarg. (Gum-elemi), Acacia choriophylla 

 Benth., Tecoma bahamensis Korthrop, Thouinia discolor Griseb., Citharexy- 

 lum quadrangulare Jacq., Chiococca parvifolia Willd., Bumelia microphylla 

 Griseb. (Ink-berry), Lantanas, Cajcmus cajan (L.) Millsp., with the vines 

 Smilax beyricUi Kunth, and Serjania subdentata (Jn&s.) Poir. Here also 

 grew Thrinax lahamensis 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 another 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 

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

 palm and Gonocarpus. 



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

 some low sand dunes where Goccothrinax jucunda Sarg. (Silver pahn) is 

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

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

 nera ulmifolia L. (here called "Buttercup"), Pluchea fmtida (L.) B. S. P., 

 BaccTiaris dioica Vahl., Petitia posppigii Schan., Ernodea littoralis Sw., Genipa 

 clusiifolia (Jacq.) Griseb., Phyllanthvs epiphyllanthus L. (Hard-head), Pithe- 

 colobium heyense Britton (Ram's horn), Gassia species, Eugenia confusa DC. 

 (Stopper), with the vines Rhabdadenia biflora (Jacq.) Mill., Urecliites andrew- 

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

 (Jacq.) Hall, species of Passiflora, and the trailing, parasitic Gassytha. 

 Chloris petrcea Desv., Setaria glauca (L.) Scribn., and Genchrus tribuloides 

 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) Pluchea odorata (L.) Cass.; (3) Lippia species; (3) Gladium effusum
