eolignitica. It is very simihir to tlio loaves of 

 several existing tropical species of Anoiia. 



I am unable to separate this striiviufi; form 

 from tlie species (lescrihinl by Eiigelhanlt from 

 the early Tertiary of Chile. The genus Psy- 

 chotria, to which it is referred, includes many 

 existmg tropical shrubs aiul trees, of wliich 

 two-thirds, or about 2o0 species, are peculiar to 

 the West Indies. Central America, Brazil, and 

 Peru. The fossil form may be cxmipared with 

 Pfiijchofria grandis Swartz, a shrubby form 

 ranging from tlie West Indies ((^uba, Jamaica, 

 etc.) to Mexico and Central ,\jnerica. 



Occurrence. — Lagrange formation (in beds of 

 Wilcox age), Purvear, Ilenrv Count v, Tenn.

 Genus ANTHOLITHUS Brongniart.

 Plate CXII, fisrure fi. 



Description. — The inflorescence shown in 

 Plate CXII, figure 6, has an extraordinarily 

 stout axis that bears a compact cluster of 

 small flowers, which are very imperfectly 

 preserved, the only feature that can he made 

 out \vith certainty being the lanceolate seg- 

 ments of the floral envelope, and these greatly 

 resemble the empty and flowering scales of the 

 grasses. Though a botanic affijiity with that 

 group is only a probalulity, it is conuuemorated 

 in the specific name chosen for this form. 



OrdiTiarily it would not be worth while to 

 describe or figure such poorly jjreservetl mate- 

 rial, l)ut though it furnishes little that is of 

 botanic interest it serves to help roujul out 

 our picture of the life along tliis early Eocene 

 coast, aiul as definite rtunains of grasses are 

 such rare fossils, even im])erfectly preserved 

 specimens are not without value. 



Occurrence. — Lagrange formation (in beds of

Plate CXII, %ur<- 1 . 



Descri,ption. — Flower cam))anulate or tubu- 

 lar; it may be interjii'eted as havuig abortcnl 

 or greatly rcihiced ])etais and a gamosepalous 

 calyx, or more probably the calyx was incon- 



spicuous and is not visil)le in the fossil, and the 

 corolla was gamopetalous. l-'eduncle about 

 6.-5 millimeters in length, slightlj' enlarged 

 distad. T!ie ovary a])pears to have been 

 inferior; that is, tlie flower was epigyuous. 

 The corolla a])])ears to liav-e been tubular, tlie 

 campanulate appearance on the left side of tlie 

 figure being due to a broken part of tlie gamo- 

 petalous corolla and not tO an individual ])etal. 

 Stamens slender, exserted, five in number. 



This species is based on the single speci- 

 men well shown in Plate CXII, figure L The 

 preservation is unfortunately not of the best, 

 the remains being flattened and the stamens 

 having lost their anthers, which it would seem 

 were versatile. With material as imperfectly 

 preserved as this specimen any extended search 

 among existing gamopetalous flowers for ]ios- 

 sible relationships is hardh^ worth while. 



Occurrence. — Holly Springs sand, Early 

 Grove, Marshall County, Miss. (coUected by 

 E. W. Berry).

Genus CALYCITES of authors. 

 Calycites nvviLLAFORMis Berrv, n. sp. 



Plate CIV', figure 7. 



Description. — This name is proposed for 

 concavo-convex, coriaceous objects, broadly 

 elliptical or orbicular in outline, about 2 centi- 

 meters long and 1.7 centimeters in maximum 

 width, slightly deflected and flanged along the 

 sides and top, the maximum width oi this 

 flange being about 2 millimeters. The tip is 

 broadly and roundly pointed. The base is 

 rounded at the sides and truncate across the 

 middle. 



This form, which appears to represent a 

 sepal, is named from its resemblance to the 

 modified inner pair of sepals in the genus Da- 

 villa Velloso of the family DiUeniacca\ a family 

 represented in the Wilcox flora by several 

 species referred to the form genus Dillenites 

 Berry and comparable for the most part with 

 the existing species of Tetracera Linne. 



The genus Davilla comprises about 25 species, 

 confined to the American Troi)ics and ranging 

 from Mexico southward, chiefly living in the 

 Brazilian region. In this genus the inner pair 

 of sepals bec(unes enlarged and forms a hard 

 leathery or woody, more (u* less nearly closed, 

 bivalve envelope, surrounding the essential
