VEGETATION OF SOUTH FLORIDA 
in a northward direction toward Princeton, a prairie was crossed to another 
area of pineland (Text Fig. 1). The fifth hollow, north of the prairie glade, was 
a small one devoted to the raising of Kaffir-corn, Sorghum halepense Pers. 
Number six was a water-filled pot-hole characterized by palmettos, Sabal pal- 
metto (Walt.) R. & S., cocoa-plum trees Chrysobalanus pellocarpus С. F. W. 
Mey., waxberry shrubs, Myrica cerifera L. and a few epiphytic tillandsias. 
On a taller palmetto was found a large fern, Phlebodium aureum (L.) R. Br. 
(=Polypodium aureum L.) with rhizomes twining about the palmetto stem. 
In the water of this hole grew Sagittaria lancifolia L. and a few sedges, while 
the soil along the low margin at one side of the hole was trodden to mud by 
cattle. The seventh banana hole was an open almost treeless one filled with 
an even mixture of saw-grass, Cladium effusum (Sw.) Torr., and Sagittaria 
lancifolia L., with two low custard-apple shrubs, Annona glabra L., while the 
hollow adjoining was filled with a scattered growth of saw-grass, Cladium 
effusum (Sw.) Torr. The ninth hollow was almost completely occupied by the 
aquatic arrowleaf, Sagittaria lancifolia L., which with its tall vertically dis- 
posed leaves, white flowers and dark-green color formed a conspicuous contrast 
to the light-green undergrowth of the pineland. A few tufts of the saw-grass 
grew along the edges of this hole. The tenth banana hole was water filled. 
Here grew in association custard-apple trees, Annona glabra L., bay-trees 
Persea pubescens (Pursh.) Sarg., cocoa-plums, Chrysobalanus pellocarpus G. F. 
W. Mey., palmettos, Sabal palmetto (Walt.) R. & S., buttonbushes, Cephal- 
anthus occidentalis L., entirely without epiphytes. 
An unusual condition was found in the eleventh depression, which was of 
small size about a meter across. Here grew a single palmetto, Sabal palmetto 
(Walt.) R. & S. about two meters tall. The twelfth banana hole partially 
filled with water was occupied by custard-apple trees, Annona glabra L., cocoa- 
plum shrubs, Chrysobalanus pellocarpus G. F. W. Mey., small palmettos, Sabal 
palmetto (Walt.) R. & S., while epiphytic orchids grew perched upon the larger 
custard-apple trees. The cat-tail, Typha angustifolia L. and the arrow-leaf 
Sagittaria lancifolia L. grew about the bases of the trees in this hole. Banana 
hole number thirteen was a wet one with an open lagoon of water. Here grew 
custard-apple trees, cocoa-plum trees, two palmettos, very much scattered in 
their disposition, together with a perennial herb, Conoclinum dichotomum 
Chapm. growing out of the water. In the water grew Sagittaria lancifolia L., 
and entirely submerged, the mermaid-weed, Proserpinaca platycarpa Small,
