Genus OREODAPHNE Nees. 



Leaves with well-markoil lateral primaries in the li)\ver 

 half of the leaf: 



Primaries extending above the middle, apex ii.sually 



obtuse Orcodaphne ohtusl/oli'i. 



Primaries not extending above the middle, apex and 



base e(iiially pointed Oinx/aplme salinennn. 



Lea^■es without well-marked lateral jtrimarie.-s: 



Liuear-lanceolale, falcate, with remote .secondaries. 



Orcodaphne pseudoguiancnds. 

 Relatively broad leaves with less remote secondaries: 

 Elongated with undulate margins. 



Ormdaphne m ississ ipp iensis. 



Short and broad with regularly rounded margins: 



Equally pointed at both ends, petiole short, 



secondaries five or more pairs, venation 



thin Orvodaphne coushatta. 



Apex slightly extended, secondaries five or 

 fewer pairs, vetialion very coarse. 



Orcodaphne uilcoxensis. 

 Apex extended, petiole elongated, second- 

 aries eight or more pairs. 



Orcodaphne purtjcarensis.

Plate I. XXXIII. figure 1. 



Description. — Leaves medium sized, ovate- 

 lanceolate in genei-al outline, with full rouiKh'd 

 lateral margins. Length about centimeters. 

 Maximum widtii about .'^ centimeters, in the 

 middle ])art of the le.'if. Apex narroweci, 

 sonu'what elongatcHl and acuminate. Basal 

 half much fuller tlian the apical lialf, iinally 

 slightly decurreiit on I he stout petiole. Mar- 

 gins entire. Texture coriaceous. Petiole long 

 and stout, 1..5 centimi-tcrs in length. Midrib 

 stout, curved, prominent on the lower surface 

 of the leaf. Secondaries stout, not prominent, 

 however, but immersed in the leaf substance, 

 about 8 pairs, irregularly spaced and diverg- 

 ing from the midrib at different angles, the 

 lower secondaries at acute angles, more or less 

 parallel in their course with the lower lateral 

 margins. Angles increase distad; the median 

 secondaries are regularly curved and campto- 

 drome at a considerable distance from the mar- 

 gins ; th(> distal secondaries are short and nearly 

 straight to the point, wIktc they bend abruptly 

 upward in flat arches approximately paraUel with 

 the margins to join the secondary ne.xt above. 



This species is not unlike Orcodaphne fwteus 

 Xees, as weU as other existing species in this 

 genus. It is also somewhat like MespiJo- 

 daphne cou.shaita Berry, from the Wilcox de- 

 posits of Louisiana. 



Occurrence. — Ackerman formation, Iltn-le^'s, 

 B(>nton County (formerly part of Tippah 

 Comity), Miss. (coUected by E. N. Lowe and 

 E. W. Berry). Lagrange formation (in beds 

 of Wilcox age), Puryear, Henry County, Tenn. 

 (coUected by E. W. Berry).
