LOWER EOCENE FLORAS OF SOUTHEASTERN NORTH AMERICA. 



In addition to the localities and collections 

 ali-eady mentioned, small lots, consisting of 

 only one or two specimens, have been received 

 from other sources but have heretofore re- 

 mained unstudied. They comprise the follow- 

 ing materials: 



Three or four specimetis were sent to the 

 United States National Museum by T. O. Ma- 

 bry, who collected them about twenty years 

 ago from the plant-bearing exposures in the 

 railroad cut just nortli of Oxford depot, Lafay- 

 ette County, Miss. 



Two or three specimens were sent to the 

 United States National Museum in 1896 by 

 C. T. Simpson from Frierson Mill, De Soto 

 Parish, La. 



A few specimens in clay ironstone were re- 

 ceived at the United States National Museum 

 in 1889 from J. W. Kelsey, who collected them 

 at KeLseys Bluff east of Early Grove, Miss. 



A small collection made by A. C. Veatch 

 between 3 and 4 miles below Hamilton on 

 Sabine River, Sabine County, Tex., was depos- 

 ited at the New York Botanical Garden. 



A small collection was sent to the United 

 States National Museum in 1889 by J. C. Bran- 

 ner, at that time State geologist of Arkansas. 

 This included a determinable specimen from a 

 well near Texarkana (U. S. Nat. Mus. No. 

 8608, collected by Prof. Moseley) ; a specimen 

 from.scc. 28, T. 2 S., R. 14 W. (U. S. Nat. Mus. 

 No. 8610, collected by R. I. Ailly); several 

 specimens from Hardys MiU near Gainesville, 

 Greene County (U. S. Nat. Mus. Nos. 8605, 

 8606, 8609, collected by J. C. Branner) ; and a 

 specimen from Scarboroughs in the vicinity of 

 the Hardys Mill locahty (U. S. Nat. Mus. No. 

 8607). These were examined by Lester F. 

 Ward, who mentions "Magnolia and an ericar- 

 coous leaf" in a letter quoted in part by Call ' 

 in his geology of Crowleys Ridge. 



During 1911 and 1914 Berry published sev- 

 eral preliminary paj^ers based on the field work 

 which has resulted in the present report. The 

 first ^ showed that the type exposures of the 

 Lafayette formation in Lafayette County, 

 Miss., were of Wilcox age. The second ' was 

 devoted to a description of a new species of 

 Engelhardtia fruit from Early Grove, Miss.,

the fii-st authentic record of this genus from the 

 Tertiarv strata of North America. Tlie tliird ' 

 included a brief general account of the Wilcox 

 flora, enumerating numerous genera that were 

 represented and giving a clear indication of its 

 wonderful diversity and richness. The fourth '' 

 described the occurrence of fruits of the Nipa 

 palm in the Greinuhi formation, the upper for- 

 mation of the Wilcox gi'oup, of Grenada, Miss. 

 It is the first and only known occurrence in the 

 Western Hemispliere of the genus Nipadites, 

 which is comnidii in the Eocene of the Old 

 World. 



A preliminary sketch ° which formed the 

 basis for the treatment of the ecology and dis- 

 tribution in this Work was read before the 

 American Philosophical Society in 1914. 



The following forms that are given in the 

 lists on the preceding pages must be dropped 

 from the literature, as they are based on frag- 

 mentary and not certainly determinable mate- 

 rial that was subsequently lost or else on abso- 

 lutely undeterminable remains. One specimen 

 is not even of an organic nature. 



Fagus fcrruginca Lesquereux, Am. Jour. Sci., 2d ser., vol. 

 27, p. 363, 1859. Recorded from Somerville, Tenn., 

 and specimen lost. Obviously not a Fagus. 



Juglans appressa Lesquereux, Am. Pliilos. Soc. Trans. , new 

 ser., vol. 13, p. 420, pi. 20, fig. G, 1869. Recorded 

 from Hurleys, Miss., and specimen lost. Not deter- 

 minable. The same remark applies to the identifi- 

 cation of this species by Knowlton (Am. Geologist, 

 vol. 16, p. 308, 1895) from Old Port Caddo Landing, 

 Tex. 



Magnolia laurifolia Harris, Arkansas Geol. Survey Ann. 

 Rept. for 1892, p. 56, 1894. Recorded from Benton, 

 Ark., and specimen lost. 



Phragmites oeningensis Alexander Braun. Determined 

 from Cross Bayou by Lesquereux (specimen No. 2532). 

 Based on a fragment of a palm ray. (Not determi- 

 nable.) 



Platanus guillelmx Lesquereux, U. S. Nat. Mus. Proc,

 in the collection.

 Philos. Soc. Trans., new ser., vol. 13, p. 413, pi. 18, 

 figs. 4-6, 1869. Based on undeterminable fragments 

 recorded from Hurleys, Miss.
