LOWER EOCENE FLORAS OF SOUTHEASTERN NORTH AMERICA. 



carry minute close-sot eremite teeth. Texture 

 coriaceous. Petiole missing. Midrib stout, 

 nearly straight, prominent on the lower surface 

 of the leaf. Secondaries medium sized, not 

 jjrouunent, numerous, diverguig from the mid- 

 rib at angles of about 50°, somewhat irregu- 

 larly spaced, straight at first, curving abruptly 

 upward about two-thh-ds of the distance to the 

 margin to form camptodrome arches. 



This species is shorter and wader than Teii^ 

 strmmites eoligniticus Berry and the teeth are 

 smaller, more close-set, and different. It is 

 much like the larger leaves of Ternstroimites 

 preclaibornensis Berry but is more abruptly 

 pointed, more narrowly decurrent, and the 

 teeth are much smaller and more numerous. 



Occurrence. — Grenada formation, Grenada, 

 Grenada County, Miss, (collected by E. N. 

 Lowe and E. W. Berry) ; Lagrange formation 

 (in beds of Wilcox age), Pm-year,Hem-y Comity, 

 Tenn. (collected by E. W. Berry). Wilcox 

 group, sec. 28, T. 13 N., R. 12 W., De Soto 

 Parish, La. (collected by G. C. Matson and 

 O. B. Hopkms).

Teknstrcemites lanceolatus Berry, n. sp. 

 Plate LXXVII, figure 5. 



Description. — Leaves linear-lanceolate and 

 many of them falcate in outline, the apex 

 acummate and the base narrowed and markedly 

 decurrent. Length ranges from 6 to 14 centi- 

 meters. Maximum width, below the midcUe, 

 ranges from 6.5 millimeters to 2 centimeters. 

 Margins entire for a short distance proximad, 

 above which they bear more or less distant, 

 very broad and shallow, crenate teeth. Tex- 

 ture coriaceous. Petiole stout, about 2.5 

 centimeters in length m the larger leaves. 

 Midrib very stout and curved. Secondaries 

 numerous, subparallel, thm, largely immersed, 

 diverge from the midrib at angles of about 45°, 

 slightly curved mitil the marguial region is 

 reached, where they are regidarly campto- 

 drome. Tertiaries thm, mostly obsolete by 

 immersion in the leaf substance, forming rela- 

 tively large four or five sided meshes. 



This species is smaller and relatively nar- 

 rower than Temstrosmites eoligniticus Berry or 

 Ternstronmites ovatus Berry. It is somewhat 

 similar to the narrower forms of Temstrosmites 

 preclaibornensis Berry, but it may be distin- 

 guished at once by its less prominent teeth, 



longer petiole, more numerous, more ascending, 

 and thmner secoudaiics. 



Occurrence. — Grenada formation, Grenada, 

 Grenada County, Miss, (collected by E. N. 

 Lowe and E. W. Berry); Lagrange formation 

 (m beds of Wilcox age), Puryear, Henry County, 

 Tenn. (collected by E. W. Berry).

Cinnamomum obovatus Berry, n. sp. 

 Plate XXIX, figure 3. 



Description. — Leaves medium sized, obovate 

 in general outline, the tip broadly nmnded, 

 perhaps abnormal, and the base gradually 

 narrowed, cmieate, and decurrent. Length 

 about 5 oentmieters. Maximum width, above 

 the middle of the leaf, about 2.1 centimeters. 

 Margins entire. Texture coriaceous. Petiole 

 shorti, very stout, curved, enlarged proximad, 

 about 7 millimeters in length. Midrib stout, 

 curved, promuiont on the lower surface of the 

 leaf. Lateral primaries, one on each side, sub- 

 opposite, thin, suprabasilar, diverging from the 

 midrib at angles of about 20°, rather straightly 

 ascending parallel with the lateral margins, 

 camptodrome m the upper part of the leaf. 

 Secondaries thin, two or three alternate camp- 

 todrome pairs in the nj)per part of the leaf. 

 Tertiaries thin but well marked, forming small 

 straight-sided arches along the primaries, mter- 

 naUy forming rather straight, anastomosuig, 

 mauily transverse veiiilets. Nervilles forming 

 small cjuadrangular or polygonal meshes. 



This species is represented by the single 

 specimen figured, which may be an abnonnal 

 variant of some other lauraceous member of 

 the Wilcox flora. If it is assumed that the
