Descriptibn.--Stout twigs, pinnately branched, covered with
large, thick, rhomboidal, squamate, densely crowded, appresged
leaves attached by practically.their whole ventral surface. PhyIlotaxy
spiral. Leaf-surface striated, the strife converging' toward
the obtuse apex. Cones n_ positively determined.
Brachyphyllum is chiefly an older Mesozoic type, but it remains
abundant through the Lower Cretaceous, two species having beert
described from the Potomac Group o,f Maryland and Virginia.
It is a waning type in the Upper Cretaceous, represented by but
a single species, the one under discussion,, which persists as high
as the Seuonian. It is widely distributed, and is recorded fronl
Long Island, Staten Island, New Jersey and Delaware, in the
east, and from the Dakota Group, of Kansas, and the Montana
Group of Wyoming, in the west? It is probably represented in
the Patoot beds of Greenland, by the material which Heer erroneously
refers (loc. cir.) to Moriconi_. While it is no_ recorded
from Europe, Velenovsky has described remains from the Cenomanian
of Bohemia, which appear to be identical with the
American repi'esefltatives, referring them to the Jurassic genus
Echi_wstrobus of Scllimperr ° Hollick and Jeffrey have recently
