FLORA OF THE WOODBINE SAND AT ARTHURS BLUFF, TEX.

The present species is also very similar to 

 Aralia decurrens Velenovsky/' from the 

 Cenomanian of Bohemia, which, however, has 

 relatively narrower and more elongated lobes, 

 with coarser teeth, and deeper sinuses. 



In reporting on a collection made by 

 Vaughan at Arthurs Bluff, Tex., and now in 

 the United States National Museum, Knowlton" 

 mentions Aralia ivellingfoniana. vangltanii n. 

 var. as the most abundant form observed. 

 This variety was distinguished from the type 

 "by its trilobate form, more slender lobes, and 

 entire margins." A study of this material has 

 satisfied me that it is not distinct from the 

 normal Aralia wellingtoniana , which shows 

 every gradation in size and ranges from entire 

 to more or less completely toothed margins.

This species was described by Lesquereux as 

 follows : 



Leaves large, subcoriaceous, triple-nerved and five- 

 lobate by di\'ision of the lateral nerves, fan-.shaped in out. 

 line, narrowed in a curve or broadly cuneate. and decur- 

 ring to a long, slender petiole", lobes narrowly lanceolate or 

 linear-lanceolate, acute or blunt at the apex, equally 

 diverging, distantly dentate from below the middle up- 

 ward ; secondary nerves subcamptodrome. * 



This Iieautiful species is known by numerous finely 

 preserved specimens- The leaves, 9 to 20 centimeters 

 long from the top of the petiole to the sumit of the middle 

 lobe, are of the same width between the points of the 

 lower lateral lobes; the petiole is long and comparatively 

 slender, though appearing thick upon one of the speci- 

 mens, probably enlarged and flattened liy compression. 

 The preserved broken part on one of the leaves measures b 

 centimetera. The lobes cut down to about two-thirds of 

 the leaves are narrowly lanceolate, slightly narrower near 

 the obtuse sinuses, equally diverging, the lower lateral 

 ones much shorter, curved down, and decurring to the 

 base of the leaves. The leaves, triple-nerved from the 

 di\ision of the primary nerves a little above the base, 

 become five-nerved from the forking of the lateral nerves 

 at a short distance from their base. The secondary veins 

 emerge at an acute angle of 30°, curve in ascending to the 

 borders, and sometimes enter the teeth by their ends; the 

 upper more generally follows close to the borders in fes-

toons, emitting under the teeth short, branches which enter 

 them. There are not any intermediate tertiary veins, but 

 the nervilles are strong, often continuous, anastomosing in 

 the middle of the areas and forming by subdivisions a 

 small quadrangular areolation. 



The material from Arthurs Bluff, Tex., is 

 scanty and not positively determined. 



Family CORNACEAE.

 Geol. Survey Prof. Paper 112, p. 129, 1919, 



Leaves elliptical, 7 to 8 centimeters in length 

 by about 4 centimeters in maximum width, 

 with an acute apex and base, the base slightly 

 decurrent and inequilateral. Margin entire, 

 very slightly and inconspicuously undulate. 

 Midrib slender and straight. Secondaries 

 slender, about seven pairs, opposite or alter- 

 nate, branching from the midrib at angles of 

 about 45° and strongly curved upward, ap- 

 proximately parallel and camptodrome; they 

 increase in length from the apex to the base, 

 the lower ones sweeping upward in strong 

 arches parallel with the margin and all drawn 

 inward toward the ape.x. 



With the exception of the delicate and some- 

 what flexuous character of the venation, these 

 leaves are strictly comparable with those of 

 Cornus, good species of which, very similar to 

 this species, occur in the Dakota sandstone of 

 the West, in Greenland, and in the Magothy 

 formation of Maryland. 



This species is found also in the Raritan 

 formation of New Jersey and the Tuscaloosa 

 formation of Alabama.
