LOWER EOCENE FLORAS OF SOUTHEASTERN NORTH AMERICA. 



Ilex vomitorl\foll\ Borry. n. sp. 

 Plate LXIV, fi.uuro li. 



Description. — Li^avcs much reduced, ovate 

 or obovate in general outliii(>, the apex some- 

 what luuTowed and roumh'd and the base nar- 

 rowly decuiTent. Lt^ngth about 1.5 centi- 

 metei-s. Maximum width, in the middle part 

 of the lesif, about 5.5 centimeters. Margins 

 entu"e at the liase, above wliich they ai-e beset 

 with shallow crenulations. Texture subcori- 

 aceous. Petiole obsolete. Mifb'ib rather stout, 

 straight. Secondaries numerous, thin, ascend- 

 ing, camptodrome. 



This uncommon species is markcfUy distinct 

 from the other members of the Wilcox flora 

 and approaches very close to the smaller 

 leaves of the existing 77(.r romitona Aiton, a 

 small tree rarely found far from salt water, 

 ranging from southern Virginia to Cedar Keys, 

 Fla., and west to Matagorda Bay, Tex. It 

 also resembles several smaU-leafed species in 

 the aUied famUy Celastraceje. 



Occurrence. — HoUy Springs sand, Early 

 Grove, Marshall County, Miss, (collected by 

 E. W. Berry). 



Collection. — U. S. National Museum.

 pi. 44, fig. 2, 1899, 



Description. — As described by Lescjuereux in 

 1878 this species shows the following cliar- 

 actcrs : 



Leaves coriaceous, oblong-ovate, broadly cuneate to the 

 base, borders irregularly di.stantly dentate; nervation 

 subcamptodronie. 



These leaves, inequilateral at the ba.se, seem like 

 pinnules of a compound leaf. The midrib is thick, the 

 secondary veins numerous, parallel, inequidistant, and 

 at an open angle of divergence either enter the point of the 

 teeth and by thin branches follow the borders in festoons, 

 or are truly camptodrome, with nervilles passing up from 

 the back of the curves into the teeth. This nervation is 

 not in conformity with that of the leaves of the dentate 

 section of Ilex; it is rather analogous to that of some oak 

 leaves. The coriaceous substance of the leaves prevents a 

 reference to Quercus. I find, moreover, in some fo.ssil 

 species of Ilex, /. slcnophylla Unger, /. hcrl/cridi/oUa lieei, 

 a related type of nervation to that of these leaves. 



The type material came from the Green 

 River formation at Green River station, Wyo., 

 a fonuation considerably younger than the 

 WOcox. In 1S09 Hollick doubtfully referred 

 a shigle mcompleto specimen from the Wilcox 

 outcrop at Coushatta to this species. Though 

 the Coushatta specimen resembles the type, 

 this identification is very unceitam; the margi- 

 nal teeth are smaller, and the secondaries 

 appear to be craspedodrome and suggest a small 

 leaf of Dillenites macrodentatus (Hollick) Berry. 

 I have not made any change, however, as the 

 available material is too scanty to warrant any 

 extended discussion of its botanic affinity, 

 although I am mclined to see a resemblance to 

 Dillenites m the material from Louisiana. 



Occurrence. — Wilcox gioup, onc-fourtli mile 

 above Coushatta, Red River Parish, La. (col- 

 lected by G. U. Harris). 



Collection. — New York Botanical Garden.

Ilex sp. Hollick, in Harris, G. D., and Veatch, .V. ('., A 

 preliminary report on the geology of Louisiana, p. 

 285, pi. 4.3, figs. 2, 3, 1899. 



Descrii^tion.- — Two fragments of a large leaf 

 with a remotely toothed margm have been 

 identified as a form of Ilex by HoUick. No 

 additional material has been collected and it 

 would be hazardous to attempt to revise or 

 certify this identification. As the specimens 

 appear to differ from all the known members of 

 the Wilcox flora, they are retained as deter- 

 mined by then- describer. 



Occurrence. — Wilcox group, Slaughter Pen 

 Bhifi^ on Cross Bayou, Caddo Parish, La. (col- 

 lected by A. C. Veatch).

Description. — Leaves smafl, lanceolate and
