28 BERRY : MESOZOIC FLORA OF THE COASTAL PLAIN 
primaries scarcely to be distinguished from the secondaries. 
Secondaries 4 or 5 subopposite pairs, rather straight, indifferently 
camptodrome or craspedodrome. Tertiaries well marked, trans- 
verse. Margins entire. (PLATE 8, FIGURE 4. 
The remains of this species arenumerous but fragmentary. In 
general outlines and venation they suggest a species of Aspidio- 
phyllum but they lack the characteristic base of that genus. There 
is some resemblance, not close however, to Arata rotundiloba 
Newb., and to Aralia nassauensis Hollick. 
Collected at the Pennsylvania Avenue locality in the District 
of Columbia. 
Hedera cecilensis sp. nov. 
Leaves of medium size, orbicular in general outline with a tend- 
ency toward trilobation, 6-7 cm. in length by about 6 cm. in 
greatest width. Margin entire, with shallow undulate lobes. 
Petiole and midrib stout. Lateral primaries suprabasilar, not dif- 
ferentiated from the secondaries in some specimens. Secondaries 
one pair below the lateral primaries and one or two remote pairs 
above, forking dichotomously and craspedodrome in _ habit. 
(PLATE 8, FIGURE 2.) 
This species resembles in a general way several which Lesque- 
reux referred to Czssztes, as for example Cissites Harkerianus and 
Cissites acuminatus, In appearance it suggests the somewhat 
larger Dakota Group leaf which Lesquereux christened Platanus 
cissoides. It is closely related to Hedera cretacea Lesq., differing 
in the suprabasilar primaries and in the details of the general 
outline. Hedera cecilensis is a very well marked species and is 
evidently allied to Hedera, clearly differentiated however from any 
of the previously described forms. The genus is rather prominent 
in Upper Cretaceous floras, both in Europe and America, the pres- 
ent species and /edera cretacea Lesq. resembling closely the ex- 
isting species. The present material is from Upper Magothy at 
Grove Point in Cecil County, from which it takes its name.
