mation is composed of more or less honey-combed rock and has the water 
constantly within a few inches of the surface. This formation, according to 
COKER, differs from the typic pine-barrens in the occurrence of Sabdal Pal- 
metto, and differs from the wetter marsh in the presence of the pine, Pıinus 
carıbaca (= P. Elliottü, bahamensis). 
The dominant growth is open and scattered and consists almost entirely of pines (20—2 
tall) and palms (15—20 feet tall), Rhus Metopium, Exostemma ar and Coccoloba laurifolia 
are scattered here and there, but hardly reach the size of tre he undergrowth is low and 
and open consisting of Corchorus hirsutus, Torrubia longifoli, Pithecolobium keyense, Tecoma 
bahamensis, Lantana involucrata, Cordia bahamensis, Bourreria havanensis, Byrsonima lucida and 
such vines as Smilax Beyrichii, Rajania hastata, Mikania heterophylla, and the parasite Cassytha 
filiformis. The principal herbaceous species in New Providence are Evolvulus sericeus, Turnera 
ulmifolia, Lippia stoechadifolia, Dieromena colorata, Chloris petraea and a little fern Ornithopteris 
adiantoides together with a species of Andropogon. 
The wet pine barrens insensibly intergrade with the dry "pine yards”. 
In New Providence‘) it extends across the central part of the island to the 
base of the Blue Hills. Pinus caribaea (= bahamensis) rarely reaches a large 
size, being generally slender and from 20 to 35 feet high. Coccothrinax 
Jucunda is next to the pine the most conspicuous and abundant tree occasio- 
nally ı2 feet tal. The orchid Bletia verecunda is common in rock holes. 
In Andros?), Pieris (Pteridium) caudata is very characteristic of the pine 
barrens. It often forms impenetrable thickets six or seven feet in height 
associated with Acacia choriophylla, Ascyrum hypericoides, Tetrazygia bicolor, 
Linum bahamense, Ernodea littoralis, Vernonia bahamensis, Dicromena colorata 
and Bletia verecunda. In many parts of the pine barrens on Andros, there 
is no underbrush, nothing but a coarse grass, Andropogon sp., relieved here 
and there by the crimson flowers of /fomoea repanda. 
Among the pines, which grow on Abaco, are found, according to COKER, Tetrazygia bicolor, 
Cordia bahamensis, Ichthyomethia pisei ipula, Bursera simaruba, Rhus Metopium, Swietenia maha- 
goni, Tecoma bahamensis, Bumelia microphylla, Acacia choriophylla, Anthacanthus acicularis, 
Duranta repens, Ernodea littoralis, Myrica cerifera, Mikania heterophylla, Rajania Bee nie 
nima Jucida, Erythroxylon brevipes, Morinda roioc, Hypelate trifoliata, Bourreria havanens 
late paniculata, Vernonia bahamensis, Gymnanthes lucida, Eugenia buxifolia, Erithalis DEREN 
Rapania guyanensis, and Coccoloba laurifolia, Ernodea Cokeri and Galium bispidulum. — Accor- 
ding to Brırro ON), an extensive pine forest similar to that on New Providence extends from 
Eight Mile Rocks nearly or quite to the extreme eastern end of Great BRAUN Island. The 
flora of this pine forest is similar to that on New Proridenis Island. 
Low Thicket Formation. These thickets are almost impenetrable because 
the trees and shrubs grow straight up and close together and the growth of 
epiphytes (bromeliads and orchids) upon them is extraordinary. An essentially 
leafless Vanil/a scrambles through and upon the shrubs, and with it Artkro- 
stylidium, a slender bamboo. This kind of thicket covers most of the northern
