 ranges from '.\.7r> to (i.o centijneters. Maxi-

 eight irregularly sjiaced pairs diverge from the 

 midrib at angles ol' about .55° or more, curve 

 regularly atul are camptodrome some distance 

 from the margins. Tertiaiies o])solete. 



This species, wliich apparently is rare, is 

 well diffcM'entiated among the ratlier numeroits 

 species ri'ferred to Sophora in the Wilcox flora. 

 It may be compared with several existing spe- 

 cies in Sophora and allicnl genera. 



Occurrence. — Lagrange formation (in beds 

 of Wilcox age), Pury^ear, Henrys County, Tenn.

Sophora hexryexsis Berry, n. sp. 

 Plate LII, fifrure 2. 



Description. — Leaflets short and bi-oadly el- 

 li]itical in outline, the apex and base lu'oadly 

 roimdeil slightly emarginate, sessile. I^ength 

 about 2.75 centimeters. Maximum width, 

 which is halfway between the apex and the 

 ])ase, about 1.75 centimeters. Margins entire 

 and full. Texture coriaceous. Midrib stout 

 and somewhat flexuous, relatively slender as 

 compared with Sophora wilcoxiana Berry or 

 Sophora paUeolobifolia Berry. Secondaries five 

 to seven pairs, thin but distinct, somewhat 

 irregularly spaced, branching from tlie midrib 

 at angles of about 60°, rather straight, ulti- 

 mately curved, and camptodrome. Tertiaries 

 forming small arches in the marginal region and 

 internally four or five sided, small meshes. 



This species is very similar to some of the 

 shorter and wider forms of Sophora wilcoxiana 

 Berry, but is readily distinguished by its sessile 

 habit, emarginate apex and base, thiimer mid- 

 rib; and more prominent tertiary venation. It 

 may be distinguished from Sophora palxololi- 

 folla Berry by its equilateral form and sessile 

 habit. It greatly resembles some of the va- 

 riants of Sophora europsea Linger, for example, 

 the leaflet figured by Ettingshausen ' from

llaciing in the Tyrol. It is represented l)y a 

 very similar but slightly larger species in the 

 llora of the Raton foi'ination in the southern 

 Rocky Mountain pro\iiice, a formation slightly 

 older than the Wilc()X.

Sophora pal.eolobifolia Berry, n. sp. 



Plate I.ri, (iRure 1. 



D(.<icription. — Leaflets elliptical in outline, 

 markedly inecjuilateral, slightly petiolulate, 

 relatively small, about 2.5 to 3 centimeters in 

 length by 1.3 centimeters in maximum width, 

 in the middle part of the leaf. Margins entire. 

 Texture subcoriaceous. Apex bluntly jjointed, 

 inequilateral. Base equally pointed and ine- 

 quilateral. Petiolule stout, about 1 millimeter 

 in length. Midrib stout, prominent, and 

 usually slightly curved. Secondaries thin, 5 to 

 7 alternate pairs, branching from the midril) at 

 angles of about 55° and curving regularly up- 

 ward, camptodrome. 



This species is readily distinguished from the 

 other Wilcox species of Sophora by its size and 

 outline. It resembles somewliat the leaflets of 

 the contemporaneous species of Pithecolobium. 

 It may be distinguished from Pithecejlohium 

 eocenicum Berry by the larger size, more 

 rounded apex, and by the stouter, more curved 

 midrib of that species: and from Piihecolohium 

 oxfordensis Berry by the very asymmetric 

 leaflets of that species and their more coria- 

 ceous texture and obsolete venation. It also 

 greatly^ resembles some of the leaflets from 

 Haering in the Tyrol, which Ettmgshausen = 

 refers to the genus Paljeolobium, which has 

 suggested the specific name that has been 

 adopted. It may also be compared with the 

 leaflets of the widespread Sophora europsea, 

 figured from Radoboj in CVoatia by linger,'' 

 and with a form from the Tertiary of Bolivia 

 described by Engelhardt * as Lonchocarpus 

 ohtusifolius. 



Occurrence. — Lagrange formation (in beds of 

 Wilcox age), IJ miles west of Grand Junction,
