LOWER EOCEKE FLORAS OF SOUTHEASTERN NORTH AMERICA. 



fliyUum tennesseensis. It luaj- be tho leaf of a 

 Castaiiea. 



Tlic present species may bo compared with 

 a number of early Eocene species described 

 from European localities, as, for example, Dryo- 

 plujUum jxitxocastanca Saporta from Sezanne, 

 France,' Dryophyllurn curticellense (Watelet) 

 Saporta and Marion, an Ypresian species,- and 

 BryopJtyUum dcwalqud Saporta and Marion ^ 

 from Gelinden, Belgium. Dryophyllurn palieo- 

 castanea is perhaps most like DryophyUum ten- 

 nesseensis but has larger and less pohited 

 teeth anil nuire nearly horizontal secondaries. 

 Dryopln/llu/n dewalquei is also much like the 

 Wilcox species but is widest near the base and 

 much elongated and narrowed distad; the teeth 

 are much more prominent and rounded. 



The medium-sized leaves of DryophyUum 

 tennesseensis are much like those described bv 

 Watelet from the Ypresian of the Paris Basin 

 as Castanea saportx,* and the smaller leaves 

 may be compared with forms described by 

 this author from the Thanetian of the Paris 

 Basm as Myrica roginei.^ 



The deposits from which the fragment of this 

 species came near Somerville were referred to 

 the Pleistocene hj Lesquereux, but they are 

 ui fact beds of Grenada or upper Wilcox age.

Description. — Leaves Imear-lanceolate in out- 

 line, verv different in size, the lenn:th ranemor 

 from 1.5 to 25 centimeters and the maximum 

 width, which is midway between the apex 

 and the base, ranging from 1 centimeter to 2.5 

 centimeters. Apex and base equally elongated 

 and gradually narrowed to a point. Margins 

 entire below for distances that differ hi different 

 specuuens, amountuig to one-fourth the length 

 m some specunens; above this region strong 

 but slightly produced serrate teeth are directed 

 outward and separated by roimded suiuses. 

 The margmal teeth are commonly spaced ir- 

 regidaiiy and are lackmg ui some of the sec- 

 ondaries. Midrib very stout and promment 

 below, generally more or less curved. Sec- 

 ondaries stout, considerablv curved, divergme 

 from the midrib at angles m excess of 45°; not 

 parallel, suice in general every other second- 

 ary is craspedodrome and terminates m a 

 margmal tooth; the alternatmg secondaries 

 diverge at a wider angle and are camptodrome, 

 as are also the secondaries m the basal part of 

 the leaf, where the margms are entire. Ter- 

 tiaries immersed. Texture coriaceous. 



This is a well-marked species, and some 

 of the characters by which it may be distm- 

 guished from the preceduig species of Dryo- 

 phyUum have been mentioned in the discussion 

 of those species. It may be compared with 

 the same group of European early Tertiary 

 species of DryophyUum, of which several have 

 already been mentioned. 



The larger leaves of the present form are not 

 likely to be mistaken for anything else, but 

 some of the smaller specimens, like the smaller 

 one figured, may be confused with the Wilcox 

 species of Banksia, cspt^cially with the not 

 uncommon species of Banksia descrilied by 

 Lesquereux as Quercus saffordi,'^ but that
