BERRY: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 401 
THE FLORA OF THE MAGOTHY FORMATION 
Numerous contributions to the flora of the Magothy formation 
in New Jersey, Delaware, and Maryland have been made by the 
writer during the past few years. The last of these, published 
early in 1910, brought the total number of Magothy species re- 
ported from Maryland up to seventy-one. The following notes 
enumerate some recent additions to this flora, bringing the total 
number of recorded forms up to eighty-eight. 
Algites americana sp. nov. 
DeEscriPTION: Thallus, as preserved in the form of dichoto- 
mously divided branches, ranging in width from 2 mm. to 5 mm., 
thin and undulating as preserved, but rather coriaceous in life, 
with slightly wavy margins. These branches are not preserved 
for lengths of more than a few centimeters, during which intervals 
they are observed to divide but once or not at all. They have 
the appearance in some specimens of radiating from a common 
center, but as their proximal parts are invariably missing this 
supposition cannot be verified. 
The Maryland remains are rare and are in the form of impres- 
sions along which recent rootlets have often permeated the argil- 
laceous matrix, sometimes giving the specimens the appearance 
of having midribs. The North Carolina remains, which are 
abundant in the Black Creek beds at certain localities along the 
Black River, often show considerable carbonaceous residuum, in- 
dicating that in life the thallus was of considerable consistency. 
OCCURRENCE: Severn River, Anne Arundel County, Md. 
CoLLections: U.S. National Museum.

DESCRIPTION: Fragments of fertile fronds, not showing any 
lamina, which appears to be reduced to short pinnate branches 
bearing one or more spheroidal bodies interpreted as sori. These 
are uniformly 1.5 mm. or slightly less in diameter. (PLATE 18,
