plants at several localities along the highway. The shell-mounds 
between Daytona and New Smyrna were carpeted, in many 
places, with a very copious growth of the sweet clover referred 
to above. Another Old World plant, common in the North, but 
rare in the South, was the great mullein (Verbascum Thapsus). 
The most conspicuous plant along the inland marshes was a 
wild verbena (Verbena tampensis) known only from middle penin- 
sular Florida, with showy heads of very large bright bluish- 
purple corollas. Often associated with it was the leaf-cup 
(Polvmnia Uvedalia), which is less frequently seen in Florida 
than in the more northern States. 
In the swamps the great magnolia was beginning to bloom and 
the low places and ditches were decorated with a generous 
growth of the obedient-plant (Dracocephalum denticulatum) and 
a milkweed of the coastal plain (Asclepras perennis). 
Further south, in the vicinity of the older settlements, particu- 
larly between Titusville and Fort Pierce, several exotics com- 
monly cultivated were found perfectly naturalized. They hac 
doubtless been growing naturally for many years in that region, 
wholly neglected by botanists. 
In one hammock near Cocoa, for example, we found not less 
than nine naturalized exotics, more than half of which had not 
previously been recorded for the flora of Florida, or even for the 
flora of the United States. They are: a Brazilian pea tree 
(Sesban punicea), Cape leadwort (Plumbago cupensis), a South 
American vervain (Verbena chamaedraefolia), a South American 
lantana (Lantana Sellowiana), white petunia (Petunia axillaris), 
Cape honeysuckle (Tecomaria capensis), two acanthus-relatives 
(Thunbergia fragrans and T. alata), and an Indian gourd { Coccinia 
cordifolia). 
A thorough search would doubtless bring more introduced 
species to light. For about these old settlements where garden 
plants have been cultivated in the perpetual warmth resulting 
from the adjacent lagoons, many plants are bound, in one way 
or another, to get beyond the gardens, and those finding con- 
genial surroundings continue to grow and spread without further 
attention.
