BERRY: MEsSoOzOIC FLORA OF THE COASTAL PLAIN 191 
GRAMINALES (?) 
Phragmites Prattii Berry, nom. nov. 
Phragmites sp. Berry, Bull. Torrey Club 34: 190. pd. rr. f. 5. 
1907. 
The present case is an admirable instance of the undesirable 
practice of not giving a specific name to specimens of somewhat 
indefinite botanical affinity which it becomes necessary to cite fre- 
quently in subsequent work and which cannot be done intelligently 
when there are dozens of ‘ Phragmites sp.” in the literature. To 
remedy this deficiency the above species is named in honor of the 
efficient state geologist of North Carolina. 
OccurRENCE: Court House Bluff, Prospect Hall, mouth of 
Harrisons Creek, Cape Fear River. 
MYRICALES 
MyrIca CLIFFWOODENSIS Berry, Bull. Torrey Club 
SEs 873 96 2 Ff. Ge 
Fruit which cannot be distinguished from that of this species, 
described from the Magothy formation at Cliffwood Biuff, N. J., is 
contained in the North Carolina collections. 
OccuRRENCE: Parker Landing, Tar River. 
POLYGONALES 
Pisonia cretacea sp. nov. 
Leaves ovate, 1.8 cm. in length by 1.3 cm. in greateat width, 
which is midway between the apex and the base. Apex wide and 
full, bluntly pointed. Base somewhat more narrowed and slightly 
decurrent. Petiole short and stout, about 3 or 4 mm. in length. 
Midrib narrowing rapidly from the base, slightly curved. Second- 
aries immersed. Margins entire. 
This species differs from the only other Cretaceous species 
known, /rsonia atavia Velen. of Bohemia, in its relatively narrower 
outline, less rounded apex and longer petiole, both forms being of 
about the same size. 
The present is the first undoubted Cretaceous species of this 
genus found in this country, and only one Tertiary species is 
known. The latter was recently collected by the writer from the 
upper Eocene of Georgia.
