80 BERRY: FLORA OF THE MATAWAN FORMATION 
Three species occur here, two of which are common to Greenland. 
On the continent of Europe we have one species in the Vra- 
connian, one in the Senonian, and the balance, which are few in 
number, Tertiary or recent. 
The early appearance of Vzburnum, one of the Syipetalae, asso- 
ciated with Aralia, both epigynous forms, suggests to Coulter * 
a connection of the Umdcllales with the Sympetalae not admitted 
in current schemes of taxonomy. 
Some have been led to doubt the authenticity of the reference 
of the Cretaceous forms to this genus. It may be noted, however, 
that most of them have leaves with well-marked characters, which 
are emphasized by undoubted remains of fruit in a number of in- 
stances. The majority of the Sympefalae are herbaceous and un- 
suited for fossilization, while Viburnum is shrubby and inhabits 
swamps and the banks of streams, thereby offering excellent 
opportunities for preservation. That it is a type of long standing 
is evidenced by the number of existing species, by the abundance 
of individuals, and their wide range. They number upwards of © 
one hundred, of subtropical and temperate eastern Asia and North 
America; Europe has but three species, two of which occur in 
northern Africa. A probably distinct phylum (Oreinotinus Orsted) 
of about thirty species inhabits Central and South America along 
the Andes, two of the species being common to Jamaica. 
Viburnum Mattewanense sp. nov. (PLATE 4, FIGURE 13.) 
A single imperfect specimen of a leaf clearly referable to this : 
genus, and differing from Viburnum Hollickii Berry from this 3 
formation in its more broadly oval outline and more decided mar- 
ginal teeth; the ascending basal secondaries are wanting and the | 
first pair leave the midrib at an angle more than twice as great a5 _ 
in V. Hollickiz. 
Leaf 7 cm. wide and between 10 and 11 cm. in length; sub- 4 
stance thin; secondaries slender and curved, more remote than if — 
the existing species ; lower outside branches of the first secondary — 
have their tips united by a thin vein parallel with the secondary, — 
indicating that the basal portion of the margin was entire; distad _ 
the tertiaries curve directly to the marginal teeth; balance of the — 
tertiaries percurrent at right angles to the secondaries.
