Apocynophyllum sapindi/olium. HoUick, in Harris, G. D., 

 and Veatch, A. C, A preliminary report on the 

 geology of Louisiana, p, 288, pi. 46, fig. 3, 1899. 



Description. — Hollick's description, published 

 in 1899, is as follows: 



Leal' lanceolate, entire, sUghtly inequilateral, narrowed 

 and decurreut for a short distance at the base; midrib 

 strong; secondaries thin and regular, leaving the mid- 

 rib at an acute angle near the base, at a slightly more 

 obtuse angle upward, running parallel to each other for 

 a short distance, and approaching each other close to 

 the margin, where they cur\'e upward; tertiary nervation 

 straight, subparallel, and essentially at right angles to 

 the secondaries. 



Complete material shows that the apex was 

 not elongated but was rather abruptly and 

 obtusely pointed, that the margin in some 

 individuals was shghtly undulate, and that the 

 petiole was very stout and about L75 centi- 

 meters in length. The dimensions of the whole 

 leaf are as follows: Length about 12 centi- 

 meters; maximum widtlt about 3 centimeters. 



Tiiis species was described from an incom- 

 plete specimen from Coushatta, La., and com- 

 pared with Ficus lanceoldta (Heer) Weber,' 

 Laurvs princeps Heer,- and Laurus primirjenia 

 Unger.^ The first is a younger composite

form, and my material shows that the present 

 species represents a leaf altogether lacking the 

 narroweil tip of Lesquereux's material. The 

 third comparison loses force from the fact that 

 such a variety of probably unrelated leaves 

 liave been referred to Ldiirns priniiijcuui, that 

 the comparison is worth but very little. The 

 second coni|)arison is valid, and I am not sure 

 that tlic southern material is not identical with 

 that from tlie Eocene of California. A similar 

 but somewhat larger leaf is figured by Knowlton^ 

 from the early l)asic breccias of Fort Union age 

 in the Yellowstone Park, and this also is very 

 close to the present form if not identical with 

 it. Laurus princeps is another species that has 

 been too freely identified from numerous locali- 

 ties and horizons, so that rather than make any 

 ill-advised changes at this time, the species 

 mider discussion is allowed to stand as described 

 by HoUick. 



It is smaller than Apocynophyllum tahillarum 

 (Lesquereux) Berry of the Wilcox flora, and lias 

 a longer petiole and much fewer secondaries.

Plate CIII, figure 4. 



Description. — Leaves relatively short and 

 liroad, ovate-lanceolate in outline, constricted 

 at the middle by a pair of deep, opposite, nar- 

 rowly pointed sinuses into a lower eUiptical 

 segment and a distal ovate-lanceolate seg- 

 ment. Base rounded. Base of distal segment 

 rounded, its apex narrowed and bluntly pointed, 

 slightly inequilateral. Margins full, rounded, 

 and entire, except for tiie sinuses just men- 

 tioned. Petiole short and stout, about 1 milli- 

 meter in length. Midi-ib stout below, becom- 

 ing thin tlistad. Secondaries numerous, jiaral-
