Description. — Leaves narrowly clongutc-lan- 

 ccolatc, slightly inc(|uila(('ral in outline, taper- 

 ing upward to an aeuminate tip, and broadly 

 pointed proxiniad. Length ranges from 10 1o 

 IS centimeters, the acuminate tips usually 

 broken off before fossilization. Ma.xinuim 

 width, in the midtUe or basal portion of the 

 leaf, L7 to 3.5 centimeters. Margins entiic, 

 irregularly undulate. Te.xture subeoriaeeous. 

 Petiole very stout, straight or curved, tumid 

 proximad, about 1 centimeter or slightly more 

 in length. Midrib stout, straight or curved, 

 prominent on the lower surface of the leaf. 

 Secondaries numerous, thin, diverging froni the 

 midrib at wide angles, manv^ of them fuUy 90°, 

 at intervals of 2 or 3 mUlimeters, generally a 

 little under 2 millimeters, pursuing a nearly 

 straight course, their tips joined by a slightly 

 arched marginal vein, parallel with and about 

 1 millimeter tlistant from the margin. 



This is a weU-marked species of a narrowly 

 lanceolate and in some specimens slightly fal- 

 cate Ficus, readily distinguishable from the 

 other rather numerous Wilcox species of Ficus. 

 It resembles in a general way certain fossil and 

 existing species in the families Apocynacea^ ami 

 MyrtacejE but can be readily matched with the 

 leaves of several existing species of Ficus. 

 Among previously described American fossil 

 species it is most like AjwcynophyUum scuddcri 

 described by Lesqucreux ' from shales supposed 

 to belong to the Green River formation of 

 Wyoming. Specimens collected by Lough- 

 ridge at Boaz, Ky., were identified by Les- 

 qucreux with the European Miocene species 

 Ficus multinervis Heer,^ to wliich they show 

 considerable similarity. The American species 

 is, however, a much more elongated leaf.

Description. — Lea\-es snuill, lanceolate in 

 outline, base pointed, slightly decurrent, and 

 tipex acuminate. One large s|)ecimen has the 

 tip nai-rowly rounded. Length ranges fi-oni 9 

 to ID.') centimeters. Maximum width, in 

 middle pari of the leaf, ranges from 2 to 3 

 centimeters. Margins entire. Texture coria- 

 ceous. Petiole short. Midrib stout, prominent 

 on the lower surface of the leaf. Secondaries 

 slender, immersed in the leaf substance, 10 to 

 12 pairs, rather remote and irregularly spaced, 

 diverging from the midiib at wide angles, 

 straight at first, curving upward abruptly in 

 the marginal region to form Hat camptodrome 

 arches. Tertiaries mostly ol)soIete except for 

 laterals parallel with and between most of the 

 adjacent secondaries. 



This lanceolate Ficus appears to be distinct 

 from previously described fossil species. It 

 resembles a number of recent species as well as 

 the leaves of the genus Pseudolmedia Trecul, a 

 genus that comprises about five species living 

 in the West Indies, Central America, :uul 

 tropical South America. It is very close to a 

 form described by Knowlton from the Raton 

 formation of the southern Rocky Mountain 

 province as Laurus ratonensis. A very similar 

 form, Ficus laqueata, has been describetl by 

 Engelhardt" from the Tertiary of Colombia.
