especial object of visiting these localities was to study and collect 
specimens of one of the very rare and very little known American 
plants called Okenia hypogaea. This plant was collected at the 
It is a beautiful vine-like plant, with silvery leaves and blue 
flowers, that creeps over the sand, and it buries its fruits in the 
sand just as the peanut does. When previously collected, and 
before its identity was known, we found it growing plentifully; 
but unfortunately the vegetation there had not yet recovered 
from the almost annihilating effects of a hurricane of the previous 
fall, and diligent search was rewarded by the finding of a single 
young seedling, which was comforting inasmuch as it indicated 
that the species is not obliterated from the flora of the United 
States. 
Referring to the above-mentioned hurricane which visited 
southern Florida last October, I may say that it was much more 
severe and destructive than newspaper reports of it printed at 
the time indicated. It was a peculiar storm in at least one 
feature. It was nearly rainless, and clouds of salt spray from 
the ocean were blown inland undiluted for miles. The effect 
of this drifting spray on vegetation, especially on the young 
growth of shrubs and trees, was quite similar to that of fire. 
Our only exploration north of Miami was confined to a line 
between Ft. Lauderdale and Miami. There the tropical plants 
are greatly diminished and plants more characteristically ‘“ Flori- 
dian” appear. The section embraces not only hammocks, 
pinelands and arms of the Everglades, but also patches of the 
so-called ‘‘scrub,” which appear to be ancient sand dunes. These 
ancient dunes do not occur further south in the state. There 
the strikingly white sand supports a growth of herbaceous, 
shrubby and arboreous plants, among which the saw palmetto, 
a widely distributed plant in the southern states, the sand pine, 
unknown outside of Florida except from a single locality in 
Alabama, shrubby oaks, some of them known only from southern 
Florida, and a broom-like plant, a relative of the northern crow- 
berry called Ceratiola ericoides, appear to predominate.
