BERRY: FLORA OF THE MATAWAN FORMATION Tl 
ceous Atlantic coastal plain from New Jersey to Greenland. 
They persist as late as the Miocene, both in Europe (Bohemia, 
France, Germany and Italy) and in the Arctic region (Kudliset). 
Schenk (/. c.) calls attention to the great resemblance to Frene- 
lopsis of the remains from the Italian Tertiary which Massalongo 
describes under the name of Awlarthrophyton and of which Fon- 
taine (1889) says: “It is difficult to believe that they belong to 
different genera.” 
The living genus is, according to modern usage, included in 
Callitris Vent., which as thus constituted becomes divisible into 
four sections: (1) Octoclinis (Frenela Benth.), (2) Hexaclinis 
(Zrenela Mirb.), (3) Pachylepis (Brongn.) = Widdringtonia Endl, 
and (4) Eucallitris (Brongn.). The first two sections with some 
seven species are confined to the Australian region, while section 
3 is confined to South Africa and Madagascar, and section 4 with 
one species, Callitris quadrivalvis Vent., is confined to the north 
coast of Africa. The habitat of the latter leads Coulter (1901) to 
suggest a recent avenue of migration through the southern Asiatic 
region, but it should be remembered that northern Africa was 
geographically and biologically a part of Europe in the upper 
Eocene, again in the lower Miocene, and finally during the early 
Pliocene, so that Calfitris guadrivalvis might well be a relict of the 
similar species we find in the European Miocene. The South 
Africa and Madagascar forms may have traversed the ancient land 
connection between Africa and Asia in order to reach Australia, 
although their absence in the present Asiatic flora is remarkable if 
this was the route taken. It is quite possible that their actual 
migration was over the land bridge formed by the northerly ex- 
tension of the continent Antarctica, which recent zoo-geographers 
are making so much use of (Blanford 1890, Forbes 1893, Osborn 
1900). 
The distribution of the Cizpresseae as a whole, in past times as 
well as in the present, while a problem so intricate as to baffle our 
present knowledge, is one of exceeding interest.
