26 FLORIDA GEOLOGICAL SURVEY-—NINTH ANNUAL REPORT. 
ORDER RANALES. 
FAMILY MAGNOLIACEAE. 
GENUS MAGNOLIA LINN. 
MAGNOLIA VIRGINIAN A LINN. SWEET OR SWAMP BAY. 
This species is represented in the Vero deposits by a follicle. It 
ranges from Massachusetts to Texas in the existing flora and is 
found in swamps and wet hammocks throughout Florida. It has 
been recorded (i) from the Pliocene of New Jersey. 
FAMILY ANONACEAE. 
GENUS ANONA LINN. . 
ANONA GLABRA LINN. POND APPLE. 
This species is represented in the Vero deposits by a single seed. 
The Pond Apple is essentially a tropical form and this is the only 
one of the numerous tropical species of Anona that reaches the 
United States. It occurs in ponds and swampy hammocks north¬ 
ward along the Florida coast as far as Cape Malabar. 
FAMILY NYMPHAEACEAE. 
GENUS BRASENIA SCHREB. 
BRASENIA PURPUREA (MICHX.) CASPARY. WATER SHIELD. 
A carpel of this species was found in the Vero deposits. The 
water shield is one of the most interesting survivals from the Pleis¬ 
tocene and its present geographical range is exceeded by few if any 
of the higher plants. It is an inhabitant of ponds and slow streams 
and in America it is found on both coasts and from Canada to Cuba 
and Central America. It is also present in Asia, Africa and Aus¬ 
tralia and was exceedingly common in Europe during the Pleisto¬ 
cene, occurring at this time also in North America. 
There is no reason why it should not be present in suitable situ¬ 
ations throughout Florida, but I do not know of any records in the 
Lake region or within some hundreds of miles of Vero.
