Dcficn pt'ion. — Leaves broadly lanceolate in 

 outlini'. Apex narrowly pointed. Base some- 

 wliat more broadly pointcil than the apex. 

 Lenijjtii ul)out S centimeters. Ma.xinuuu width 

 about "-'..j centimeters, at a point about halfway 

 between the apex and the base. Margin entir(>. 

 Texture coriaceous. Petiole stout, curveil, 

 less than 1 centimeter in length, tumid pro.xi- 

 nnid. Midril) stout and prominent on lower 

 surface of the leaf. Secondaries thin, 8 to 10 

 subopposite pairs, l)ranching from the midrib 

 at angles of abou.t .j.")°, ratlier straight at first, 

 then curving upward and cam])todrome. Ter- 

 tiaries mostly tilisolett'. 



This species is mucii like the preceding species 

 but differe in its smaller size, more lanceolate 

 form, and straighter secondaries. It is mucli 

 like Banisteria laurifolia of the American trop- 

 ics and very similar to the Oligocene form, Ba- 

 nisteria sotzkiana, described i)y Ettingsiuiusen* 

 from Sotzka, Styria. It is apparently less com- 

 mon in the Wilcox than the preceding species. 

 Specimens collected from Wickliile nniny yeai-s 

 ago were identified by Lesquereux as Sapindus 

 duhius. 



Occurrence. — Lagrange fonnation (in IxhIs of 

 Wilcox age), Wicklifl'o, Ballard Comity, Ky. 

 (collected by R. H. Loughridg<0, and l.» miles 

 west of Grand Junction, in Fayette County, 

 Tenn. (collected by E. W. Berry).

Description. — Small winged fruit or samara, 

 about twice as long as high, the lower margm 

 evenly romided, the column straiglit and thick- 

 ened and the upper margin imdidato, the 

 oblic[ue tip roimded. Essential part of the

Genus HIRiB.\ Jacquin. 



HiR^A WILCOXIANA Bcrry, n. sp. 

 Plates LVn, figure 8, and CIX, figure 6. 



Description. — Leaves ovate-lanceolate and 

 more or less f;dcate \n general outline, widest 

 below the middle, tapering to the cimeate base 

 and more gradually upward to the narrowly 

 extended acuminate tip. Length about 10 

 centimeters or slightly more. Maximum width 

 about 3.3 centimeters. Margins entire. Tex- 

 ture subcoriaceous. Petiole very stout, curved, 

 chaimeled, about 1 centimeter in length. Mid- 

 rib curved, very stout ami prominent on the 

 lower surface of the leaf, channeled on the 

 upper surface. Secondaries relatively thin, 

 not prominent; about 10 to 12 subopposite to 

 alternate pairs diverge from the midrib at 

 angh^s of about. 55°. They are relatively 

 straight until they approach th(^ margins, 

 where they curve more abruptly and are camp- 

 todrome. Tertiaries thin and largely obso- 

 lete, mostly close and percun-ent, their prevail- 

 mg course nearly at right angUss to the mich-ib. 



This species is closely comparable with the 

 leav(!s of the existing species of Hira'a. Th<i 

 modern forms are excdusively American. They 

 number more than a scon* and range from 

 Mexico and the Antilles throughout northern 

 South Anu^rica to Peru. Ettiiigshausen - has
