BERRY: MESOZOIC FLORA OF THE COASTAL PLAIN 183 
crops, and furnishes confirmatory evidence of the variety and 
abundance of the Araucarieae in our southern coastal plain during 
the first half of the Upper Cretaceous. 
The present species is named for Prof. William B. Clark, 
geologist in charge of the cooperative investigations of the coastal 
plain in North Carolina. 
OccuRRENCE: Court House Bluff, Cape Fear River. 
BRACHYPHYLLUM MACROCARPUM Newb. (?) Fl. Amboy Clays 
51 (footnote). ~/. 7. f. 1-7. 1896 
This species was collected by the writer on July 13, 1907, but 
the specimens were destroyed during shipment, for which reason 
the occurrence is queried, although there is no doubt as to its 
authenticity, especially as the writer has recently collected it a 
short distance south of the state boundary in South Carolina. 
OccuRRENCE: Court House Bluff, Cape Fear River. 
Androvettia carolinensis sp. nov. 
Remains of leafy twigs consisting of much flattened, phylloclad- 
like, opposite twigs, the leaves on the flat surfaces being reduced 
to mere points and not visible without magnification, the marginal 
leaves strictly opposite and represented by a regular alternation 
of a blunt dentate lobe and a serrate point, the leaves being fused 
proximally. Venation consisting of immersed vascular bundles 
not seen except ina strong transmitted light. Midvein strong and 
straight ; lateral veins, which are the midveins of the coalesced 
leaves, pinnately arranged and single in the pointed leaves; in the 
rounded leaves they are usually dichotomously forked but in this 
case the marginal lobes may represent two coalesced leaves ; their 
angle of divergence greater than in Androvettia statenensis and the 
whole arrangement more distinctly cyclic in character. Texture 
very coriaceous, the epidermal cells, however, large, though with 
thick walls. Stomata fairly numerous, apparently on both sur- 
faces, and consisting of sausage-shaped guard cells surrounded by 
four accessory cells. (PLATE 19, FIGURES I-6.) 
The general appearance of this species is even more fern-like 
than in the type of the genus, one reason being its smaller size and 
the absence in the collected material of the supposed male aments 
found in connection with some specimens of the Staten Island 
species. The present species is confined to the Tar River 
exposures of the Black Creek beds and is therefore considerably 
younger than the Staten Island form.
