TRANSACTIONS OF WAGNER 



VEGETATION OF SOUTH FLORIDA 



and Isnardia natans (Ell.) Small, associated with protruding saw-grass, 

 Cladium effusum (Sw.) Torr. The wet sink designated number fourteen was 

 a small one filled with palmettos, cocoa-plums, custard-apples, waxberry bushes 

 and a few sedges. 



Banana hole fifteen was a middle-sized, circular depression completely 

 fringed by dwarf palmettos, Sabal palmetto (Walt.) R. & S., and filled, except a 

 small central lagoon, by spreading custard-apple trees, Annona glabra L., 

 loaded with epiphytic orchids and tillandsias. The fern, Phlebodium aureum 

 (L.) R. Br. ( = Polypodium aureum L.), grew attached by its rhizomes to the 

 palmetto, while associated with the custard-apple trees grew cocoa-plums, 

 Chrysobalanus pellocarpus G. F. W. Mey., three meters tall and waxberry 

 bushes, Myrica cerifera L. The water of the lagoon was characterized by the 

 scattered growth of Sagittaria lancifolia L. This was perhaps the most beauti- 

 ful and interesting of the banana holes studied by me. A few willow trees, 

 Salix longipes Anders (?), characterized the sixteenth limestone pot-hole filled 

 with water. 



The last hole (No. 17) before reaching Princeton was much altered by 

 fire, showing that a hot forest fire* would entirely exterminate the banana- 

 hole plants. The original vegetation, as attested by its remains, consisted 

 of palmettos, Sabal palmetto (Walt.) R. & S., cocoa-plums, Chrysobalanus 

 pellocarpus G. F. W. Mey., willow, Salix longipes Anders (?), draped with the 

 bullace-grape, Vitis Munsoniana Simpson, and the twining perennial com- 

 posite, Mikania batatifolia DC., while Isnardia natans (Ell.) Small grew 

 as the only submerged herbaceous plant. 



Enumeration of the Species. Twenty-three species are mentioned in the 

 description of the seventeen banana holes in the two kilometers of pineland 

 between Naranja and Princeton in South Florida. This list would be consid- 

 erably augmented, if we included the several species of Tillandsia and epiphytic 

 orchids found attached to the prevailing tree growth. Only the most con- 

 spicuous plants have been mentioned. The algae, fungi, lichens, and mosses 

 have been disregarded, as also the plants occurring in the big and little ham- 

 mocks at Detroit. Systematically the species are arranged as follows, while 

 the numerals indicate the particular banana hole where the species were found.
