further out and Rarzophora mangle gives evidence of the brackish character 
of the water. — Sabal Palmetto occurs also in a sand inlet in Eleuthera island, 
where it occupies a marshy depression, where it no doubt is able to procure 
supplies of fresh water. — About one mile from the shore on Cat Island are 
a series of fresh-water pools (unusual in the Bahamas) in which grow Urri- 
cularia sp., Nymphaea ampla, while along the edges were found Spigelia 
anthelmia, Sabbatia campanulata, Centella repanda. On New Providence, the 
plants of the fresh marshes are Myrica cerifera, Baccharis angustifolia and 
Sagıttarıa lancıfolia. 
Salt Marsh- and Mangrove-Formations. Directiy south of Nassau, New 
Providence Island is a large tract of marshy land with a considerable pond 
of water that rises and falls with the tides. The rocks margining this pond 
are covered with a swamp marl favorable only for the growth of such resistant 
species as Aszer tenuifolius and Distichlis maritima. Behind these where the 
honeycombed rock is exposed grow dwarf forms of Conocarpus erectus var. 
sericea and Rhachicallis maritima with Cassytha running along from plant to 
plant. — Certain depressions in Green Bay are brackish and here are found 
Anona palustris, Cladium, Conocarpus, Avicennia nitida. In a long, brackish 
marsh a few hundred feet behind the beach was a fine association of Typha 
domingensis and Eleocharis cellulosa. Except at this place, 7ypha was seen 
only on New Providence, where, according to COKER, it is abundant at Lake 
Killarney. The immediate shores of a large salt-water pond on Rum Cay are 
characterized by the presence of Rhizophora mangle. 
A Conocarpus Flat Formation extends on Watlings Island some distance back from a 
marsh. The ground is a honeycombed rock with water in the holes. Conocarpus erectus var. 
sericea grows here in almost pure association. At certain places on Abaco, the Conocarpus-flat 
is bordered with an association of Aster tenuifolus, Distichlis maritima aa Salieornia ambigua. 
The Conocarpus-Mangrove Formation exists on Watlings Island about 8 feet high. 
Except near the shore of a lake where it occurs, there is a pure growth of Conocarpus, but on 
the water’s edge Rhizophora mangle forms a fringe together with Avicennia nitida. On the sandy 
margins of the lake also grow Hippomane mancinella, Batis maritima and Lithophila vermicularis ?). 
Salinas Formation. This formation (also Swash) oceupies depressions in the scrub in 
which has collected the wash from the surrounding ridges of rock or sand, the resulting soil being 
a sticky compound, especially when wet. The salinas are more or less occupied by ponds and 
lakes connected together in wet weather. The ground almost flat is covered with small mangroves, 
Rhizophora, the salt-bush, Avicennia and a low form of Conocarpus erectus not more 
than a few feet in height. One or two species of Salicornia also are found, and in general the 
plants of this formation are quite scattered, and a considerable distance apart. The monotony of 
the landscape is varied near the creeks by three species of palms: the “silver thatch”, 
ırinax bahamensis; the *hog cabbage”, Cyclospathe Northropii; the “saw-tooth cabbage”, Paurotis 
androsana: all of ER size 2), 
The Savanna Formation is coincident with large flat plains in Great 
Inagua covered in great part with Sporobolus virginicus. Here and there
