300 Brrry: MESOzoOIC FLORA OF ATLANTIC COASTAL PLAIN 
the fossil state from the Dakota and Magothy formations upward. 
It is especially well represented in the Paleocene of Europe and 
in the Shoshone group of America. Of the two species in the 
Dakota sandstone of the West, one occurs in the Tuscaloosa 
formation at Cottondale, Alabama, and the other in the Magothy 
formation of New Jersey. 
OccURRENCE: RIPLEY FORMATION, McNarry SAND 
MEMBER. Near Cypress and two and one half miles southwest 
of Selmer, McNairy County, Tennessee. 
MYRTALES 
MYRTACEAE 
Myrcia DeCandolle 
Myrcia havanensis sp. nov. 
Leaves linear-lanceolate in outline, falcate, about 9 Ca. in 
length by 1 cm. in maximum width, which is in the lower half of 
the leaf. Margins entire. Apex gradually narrowed, acuminate. 
Base narrowly pointed, decurrent. Petiole very stout, tapering 
upward, 1.75 cm. in length. Midrib stout, curved. Secondaries 
numerous, thin, somewhat irregularly spaced, 2-6 mm. apart, 
branching from the midrib at angles of about forty degrees, 
running with but slight curvature to the well-marked and nearly 
straight longitudinal vein which forms a marginal hem less than 
one half a millimeter from the margin. Texture coriaceous. 
The present species is very close to some of the numerous 
forms which have been from time to time referred to Eucalyptus 
Geinitzi (Heer) Heer. It is, however, distinct from the latter, 
especially when compared with Heer’s type or with the more 
typical American material. In general it is a smaller leaf with @ 
larger and longer petiole, an outline less inclined toward ovate, 
and relatively much more produced apically. It is typically 
Myrcia-like in all of its characters. It is found in both the 
Ripley and Eutaw formations in Alabama and Tennessee. 
Occurrence: EUTAW FORMATION. Two miles south 
of Havana, Hale County, Alabama. RIPLEY FORMATION, 
MCNarry SAND MEMBER. Two and one half miles southwest of 
Selmer, Big Cut on Southern Railway near Cypress, McNairy 
County; Camden, Benton County, Tennessee.
