naturally on Andros. An exceptionally large percentage of the 
plants are native, mainly because such a small area of the island 
is inhabited and cultivated. Less than half a dozen species are 
endemic. 
glance at a map of Florida and Andros will show the striking 
resemblance of Andros to southern peninsular Florida. The re- 
semblance not only exists in the outline of Andros, but we have 
there the rock backbone corresponding to the east coast of 
carried further, for, on the eastern coast, is the deep tongue of 
the ocean in place of the Gulf Stream and on the western coast 
lies the shallow Bahama Bank in place of the Bay of Florida and 
the adjacent Gulf of Mexico. This much for the geography; 
topographically, the rock ridge of Andros and adjacent pinebelt 
correspond to the Everglade Keys of Florida, while the marl and 
the savannahs with their patches and narrow strips of pine-land 
represent the Everglades themselves. In fact, we were in many 
situations, where the surroundings were so strikingly similar to 
those we were accustomed to in Florida that a second thought 
was often necessary in order to definitely locate ourselves. After 
tabulating the species of flowering plants known to occur in 
southern peninsular Florida and Andros, we find about three 
hundred and fifty species out of the five hundred and fifty growing 
on Andros, common to both places. Leaving out of consideration 
the host of strictly Floridian plants common to the two regions 
just mentioned, and also those that occur in both Andros and the 
coastal plain of the United States, it may be interesting to note 
a small group of species that seem perfectly at home in both the 
temperate Allegheny Mountains and tropical Andros. Among 
these are the cat-tail, Typha angustifolia, the pond-weed, Potamo- 
geton heterophyllus, the green-briar, Smilax laurifolia, the smart- 
weed, Persicaria punctata, the Virginia creeper, Parthenocissus 
quinquefolia, the dodder, Cuscuta Gronovii, the fleabane, Leptilon 
canadense, and the fire-weed, Erechthites hieracifolia. 
Having explored the territory as planned, except as local con- 
ditions made changes necessary, we returned to New York about
