the United Stntos, some of wliicli vnngv nortli- 

 ward as far as Canada. There are also live or 

 sLx species in Central America. Thc^ genus is 

 distinctly not a strand jilant, but it occurs for 

 the most part in open inesoj^liile forests and 

 broken thickets of tlie warnu-r t('ni])erate and 

 tropical zones. 



Occurrence. — Holly Springs sand, Early 

 Grove, Marshall County, Miss, (not rare) (col- 

 lected, by E. \V. Beirv'i, and Lamar, Benton 

 County, Miss., in clay ironstone (collected by 

 L. C. Johnson). Wilcox group, Coushatta, 

 Red River Parish, La. (collected by G. D. Har- 

 ris), and 1,000 yards below Pope Bend, Colo- 

 rado River, Bastrop County, Tex. (collected by 

 Alexander Dcussen). Lagrange formation (in 

 beds of Wilcox age): H miles west of Grand 

 Junction, in Fayette County, Tenn. (four speci- 

 mens); 1 miles south of Grand Junction, in 

 Fayette County, Temi. (very abundant); Pur- 

 year, Henry County, Tenn. (rare); (all col- 

 lected by E. W. Berry) ; and Hatchie River 

 near Shandy, Hardeman Comity, Temi., m clay 

 ironstone (collected by L. C. Johnson).

Description. — Leaves compound. Leaflets as 

 a rule relatively large, elliptical and more or 

 less inequilateral in general outline, the apex 

 blxmtly pointed, and the base broad, inecpiilat^ 

 eral, and probably sessile. Length about 1L5 

 centmieters. Maximum width, in the middle 

 part of the leaflet, about 4 centimeters. Mar- 

 gins carry distant and small dentate teeth,,scpa- 

 rated by wide, shallow, evenly curved sinuses. 

 Texture coriaceous. Midrib stout and very 

 prominent on the lower surface of the leaflet, 

 in many specimens curved distad. Seconda- 

 ries stout and prommcnt, irregularly spaced, 

 craspedodrome; they diverge from the midrib at 

 wide angles, ranging from 60° in the upper part 

 of the leaflets to 90° in the basal part; they are 

 nearly straight for two-thirds of the distance to 

 the margin, where they generally fork, one 

 limb curving upward and the other downward 

 and outward and both terminating in marginal 

 teeth. Tertiaries numerous, tliin, and percur- 

 rent. Ai\ exceptionally small leaflet of tiiis 



species is lanceolate-falcate, has a niarke<lly 

 iiu'(piilateral base, and measures 6.5 centime- 

 ters in lengtii ])y L75 centim(>ters in maximum 

 width. Two specimens from Louisiana that 

 iivo somewhat doubtfully i-cfcrrcd to this species 

 measure 13 by .S ceiitimc^ters and 9 liy 2.1 cen- 

 t imeters, respectively. 



'i'lie leaflets of this species are not uncom- 

 mon at Puryear. In genei'al aspect they sug- 

 gest the leaflets of some species of Juglandacea>, 

 but tiiey sliow dilTerenc(>s in marginal and vena- 

 tion characti'rs and are on tiie whole more like 

 the leall(>ts of the existing species of Cujjania, 

 sev(!ral tropical American species of which are 

 very close to the fossil form. 



The genus Cupania Linne comprises more 

 than 30 existing species in the flora of tropical 

 and suf^tropical America. It is common in the 

 West Inilies but no longer hves on the Florida 

 mainland. Fossil species, represented by Inith 

 leaves and fruits, are represented in certain 

 European Tertiary deposits. Those botanists 

 who doubt determinations based on foliage 

 must regard it as a striking coincidence that the 

 seven species of Cupania leaves reported by 

 Ettingshausen ' from tiie clays of Alum Bay 

 (Ypresian) should be represented at the syn- 

 chronous horizon on the Isle of Sheppey, so 

 famous for its pyritized fruits, by eight charac- 

 teristic species of Cupania fruits and seeds. - 



Occurrence. — Lagrange formation (in beds of 

 Wilcox age), Puryear, Hemy County, Tenn. 

 (collected by E. W. Berry). Wilcox group, 3 J 

 miles southeast of Naborton, De Soto Parish, 

 La. (coUected by G. C. Matson).
