the pinnately veined and the pahnately veined types. There are 

 three or four species of Sapiiidiis — another strand type of the mod- 

 ern equatorial and subequatorial zones. Other members of the 

 strand flora include representatives of the genera Conocarpns, 

 Giietteria, Miinusops, Pcrsoonia, Tcrniiiialia, etc. Leaves of several 

 species of live oaks (Qiicrciis) are abundant. The collections also 

 include fruits of the families Anacardiaceae and Umbelliferae, and of 

 the genus Aristolochia. Curious elements common to Europe are 

 several species of Banksia. an antipodean genus in the existing flora. 

 There is a fine species of Ccrcis, a very common Enonymus and at 

 least two species of Engclhardtia based upon the characteristic 

 fruits as well as leaves. The latter genus has a single existing 

 species in Central America and several in Asia, where they range 

 from India to the East Indies. It is common in the European 

 Tertiary, but has not previously been known with certainty from 

 North America. An interesting member of this flora is a large 

 digitate species of Orcopaiia.v, a modern tropical type, abundant in 

 Central America. 



The flora as a whole contains no strictly temperate elements, 

 although many of the genera contain modern forms which range for 

 more or less considerable distances in the temperate zone. Such a 

 flora could scarcely flourish under existing conditions north of 

 latitude 29°. In its general facies it is subtropical and a number of 

 the forms indicate a high percentage of humidity, and well dis- 

 tributed and abundant seasonal rains, although this latter feature 

 tends to be obscured by the large number of the inhabitants of the 

 sandy shores which are preserved while the inland and river bank 

 dwellers are less fully represented. A majority of the elements in 

 this Wilcox flora could be duplicated today on the Florida Keys and 

 the southern peninsular mainland of Florida. 



Additional members of this flora not enumerated in the preceding 

 paragraphs include representatives of the genera Apocynophyllum, 

 Calamopsis, Ccanothns, Celastnis, Ccltis, Cordia, Diospyros, Dryo- 

 phyllum, Magnolia, Malpighiastrnm, Ncrium, Rhamnus, Rhus, 

 Sabal, Sapotacites, etc., nearly all of which are new to science.
