Oreopax.vx minor Berry, n. sp. 



PhUe XCIX, figure 1. 



Description. — T.,eaves relatively small, digi- 

 tately compound. Petiole long and stout, 

 slightly tumid at the apex and base, about 6 

 centimetei-s in length. Leaflets at least four, 

 and probably from five to seven in number, 

 lanceolate, with entire margins and narrowly 

 point(Hl tips and bases, very slightly petiolu- 

 late. Midribs stout. .Secondaries thm, di- 

 verging from the midrib at wide angles, curved, 

 camjjtodrome. Texture coriaceous. 



This species is unfortunately ])ased on very 

 fragmentary material, the most comjdete speci- 

 men being the one figured, which, though poor, 

 shows clearly the petiole and leaf ha])it. The 

 rarity of this form would indicate an iidand or 

 ujdand habitat, specunens now and then being 

 brought down to the Ijasin of sedimentation by 

 streams. 



It is too incomplete to merit a (k^tailed com- 

 parison with Recent forms tlnit reseml^le it in a 

 general way. It is readily distmguishable from 

 the robust Oreopanax o.xfordensis Berry as well 

 as from the previously descrilxul fossil species, 

 which are mostly European. 



Occurrence. — Lagrange formation (in beds of 

 Wilcox ago), Puryear, Henry County, Tenn.

lateral, the ti|) somewhat narrowed and acumi- 

 nate and the base rounded or very liroadly 

 pointed. Margins entire, in some specimens 

 faintly umhilate. Texture subcoriaceous. 

 Midrib stout and prominent. Secondaries 

 stout ; six to nine pairs, diverge from tlie midrib 

 at irregular intervals at angles of about 4')°, 

 cainplodrome. 'I'ertiaries distinct, pereurrent. 

 Tlie single Louisiana specimen has a length of 

 l(i centimeters and a maximum width mid-

 continK^tt^rs. 



This sptH-ies is represented in the Wilco.x 

 flora by numerous fragments, the single speci- 

 men figured l)eing the most complete. It is 

 certaiidy identical with the material described 

 by Lestiuereux from the Denver formation and 

 with that descril)ed by Knowlton from the 

 Raton ft)rraation. I have queried the determi- 

 nation, ior its identity with the type material 

 of Heer from the Acjuitanian of Switzerland 

 is extremely doubtfid. Heer's specimen is not 

 only nuich younger, but the leaves are smaller 

 and there art^ minor differences of venation. 

 I imagine that it is really a species of Ficus 

 instead of a Cornus, and Schenk - makes the 

 same suggestion in regard to the European 

 form. Rather than obscure its value in cor- 

 relation l)y transferring it to another genus, 

 especially as my material is so poor, I have 

 allowed it to remain in Cornus. It may be 

 more properly compared with the European 

 Paleocene species Cornus platiipliyUn Saporta'' 

 and Artocarpoides conoceplialoides Saporta.''
