BERRY: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 401 
which is exclusively American in the existing flora, is made a sub- 
genus of Ocotea Aublet by Pax in Engler and Prantl’s Die Natiir- 
lichen Pflanzenfamilien. The latter genus, which for paleo- 
botanical purposes may be considered as composite, has about 
two hundred modern species, occurring chiefly in the American 
tropics and ranging from southern Florida to Brazil and Peru, 
but with some representation (subgenus Mespilodaphne Nees) in 
the Canary Islands, South Africa, Madagascar, and the Mascarene 
Islands. 
The single existing American species reaching the United 
States, whose habit and environment may be taken as typical for 
the whole genus, is found in Florida, southward from capes 
Canaveral and Romano along the shores and islands with the 
exception of some of the western keys, making its best growth 
in the rich, moist, hammock lands near the coast. 
CINNAMOMUM MEMBRANACEUM (Lesq.) Hollick 
Paliurus membranaceus Lesq. Am. Jour. Sci. 46: 101. 1868. 
Cinnamomum membranaceum Hollick, Mon. U.S. Geol. Surv. 50: 
75: pl. 29. f. 5, 6. 1907. 
Two leaves of this species, identical with Hollick’s fig. 6, except 
that one js slightly smaller, were found at Arthurs Bluff. The 
Previous occurrences are the Dakota group and Glen Cove, Long 
Island (Raritan or Magothy formations). 
LAURUS PLUTONIA Heer 
Laurus plutonia Heer, Fl. Foss. Arct. 67: hh. 20. J. 30, O74; 
bl. 20. f. 3a, 4-5; bl. 28. f. 10, 11; pl. 42. f. 4b. 1882. 
This species was described by Heer from the Atane beds of 
West Greenland and a large number of somewhat variable and 
fragmentary specimens were figured. Subsequently it was re- 
Coded from a very large number of Cretaceous plant beds, so 
thatits range, both geographical and geological, is rather extensive. 
A number of these records are not entirely above suspicion, and 
S appears to be especially true of the forms from the Cenomanian 
of Bohemia identified by Velenovsky. 
“rus plutonia is rare in the Raritan, the writer having found 
tt only near the top of that formation. It is abundant in the
