small clumps of trees dot the surface of the savanna consisting of Swietenia 
mahagoni‘). On Andros the savannas are level prairie-like stretches covered 
_ with a coarse sedge Cladium jamaicense, the saw grass of the natives. Ter- 
minalia spinosa forms occasional clumps while Zlaveria linearis, Polygala 
Boykini, Eustoma exaltatum, Gerardia purpurea, Aletris bracteata, Spiranthes 
tortilis, Calopogon pulchellus, Buchnera elongata and Samolus ebracteatus are 
also inhabitants of these savannas’). 
Sea Cliffs and Rocks. The north shore of New Providence differs 
from the south shore by its rocky character. Sand covers the rocks in places. 
In many places, however, the exposed rocks are covered with a dense growth 
of Rhachicallis maritima and Suriana maritima in pure association. Behind 
this association is Coccoloba uvifera and Genipa clusüfolia. 
On Andros Island, the rock surfaces are characterized by Portulaca oleracea and on the 
slopes of hills grow Lysiloma paucifolia, Swietenia mahagoni, Coccoloba laurifolia, Bursera sima- 
ruba, Acacia choriophylla, Rhus Metopium and Eugenia confusa. Covering the barren rocks 
behind the beach on Green Cay is a low growth of Ernodea littoralis, Genipa clusiifolia, Cates- 
baea were Antirrhaea myrtifolia, while Passiflora foetida grows among these shrubs. The 
rocks behind this sand inlet show a low coppice of Sideroxylon mastichodendron, Zanthoxylum 
pterotä, he Torrubia longifolia, Amyris elemifera, Bursera simaruba together with Opuntia 
a. — The bare rocks on Eleuthera support among other plants Suriana maritima, Borrichia 
glabra, Rhachicallis maritima, Sesuvium portulacastrum. — Growing in small rock pockets, according 
to my observations at Matthewtown, Great Inagua, grow Portulaca oleracea var. parvifolia, and 
back of this plant in the treeless area are found Coccoloba uvifera, Tournefortia gnaphalodes, 
Bucida buceras, Rhachicallis rupestris. These form an association which may be designated the 
Tournefortia-Coccoloba Association). 
The depressions in the rocky plain show a type of vegetation in every respect different from 
the ordinary level, which may be designated as Banana Holes. In such an hole on Eleuthera 
thirty feet across grew Anona palustris, Ficus sapotaefolia, Pieramnia pentandra, Psychotria undata 
and Cladium effusum. Attached to the sides of the “sink” beneath its overhanging edges flourish 
Adiantum melanoleucum and Lindsaya clavata. 
The absolutely bare rocks near Gregory Town, Eleuthera, are character- 
ized in the crevices by Serjania diversifolia, Cissus sicyoides, Ampelopsis 
(Parthenocissus) quinquefolia, Galactia Rudolphioides, Rhabdadenia biflora, 
Smilax Beyrichü. In the deep depressions of these vine-clad rocks grow 
Bursera simaruba, Bumelia microphylla, Ficus sapotaefolia and Phyllanthus 
epiphyllanthus. 
On the top of ridges on Rum Cay among the hard smooth rocks grow Gossypium bar- 
badense (absolutely wild), Agave rigida, Plumeria obtusa, Guaiacum sanctum, Guettarda scabra, 
'Bumelia loranthifolia, B. microphylla and Reynosia septentrionalis. — Growing on the rocks of 
Little Inagua Island were found by NasH Melocactus sp., Agave sp., Opuntia sp., Thrinax keyensis, 
Pilocereus sp., etc. 
Pine-Barren Formation. The ground of this: formation is either wet or 
dry. In New Providence and elsewhere in the Bahama islands the wet for-
