Myrcia havanensis Berry, " Torrey Bot. Club Bull.," vol. 43, p. 300, 1916. 



Eucalyptus attenuata Ward (not Newberry), " U.S. Geol. Survey, Fifteenth Annual Report,' 3 

 p. 371, 1895. 



Leaves linear-lanceolate in outline, falcate, about 9 centimeters in length by 1 centimeter 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 centimeters in length. 

 Midrib stout, curved. Secondaries numerous, thin, somewhat irregularly spaced, 2 to 6 millimeters apart, 

 branching from the midrib at angles of about 40°, running with but slight curvature to the well- 

 marked and nearly straight longitudinal vein which forms a marginal hem less than 0-5 millimeter from the 

 margin. Texture coriaceous. 



The present species is very close to some of the numerous forms which from time to time have been 

 referred to Eucalyptus Geinitzi (Heer) Heer. It is, however, distinct from that species, especially when 

 compared with Heer's type or with the more typical Americal material. In general it is a smaller leaf, 

 has a larger and longer petiole and an outline less inclined toward ovate, and is relatively much more 

 produced apically. It is typically Myrcia-l\ke in all of its characters and is readily distinguishable from 

 the forms from the Tuscaloosa formation which have been referred to Eucalyptus Geinitzi in this work. It 

 is confined to the basal beds of the Eutaw formation in Hale County, Ala., and the Ripley formation in 

 western Tennessee, and takes its name from the town of Havana, near which the leaf-bearing laminated 

 clays of this formation outcrop. A single specimen collected by R. T. Hill in 1891 at the big cut on the 

 Southern Railway east of Pocahontas, Tenn., and identified by Ward as Eucalyptus attenuata Newberry, 

 proves to belong to this species (pp. 125-6).

This species has a wide range. It was described originally from the Cenomanian of Moravia, and 

 has since been recorded from a number of other European Cenomanian localities, from the Atane beds 

 of Greenland, the Dakota sandstone of the West, and from Martha's Vineyard to Alabama along the 

 Atlantic coast. It ranges upward into the Black Creek formation of North Carolina, and is not rare in the 

 Middendorf arkose member of the Black Creek formation of South Carolina. In Alabama the species 

 is not common, but this may simply be due to accidents of preservation, (pp. 126-7.)

(See p. 237.) 



. . . According to long-establlshei usage, therefore, this species and Eucalyptus Geinitzi and 

 E. augusta are referred to the genus Eucalyptus, although it seems more probable that they represent the 

 ivavis Myrcia of this same family, or its ancestral stock, (p. 126.)
