The following were contained in a collection 

 from a locality 10 miles south-southwest of 

 Palestine, Anderson County, Tex., in Post Oak 

 Prairie, 2 miles south of Needmore (collectors, 

 O. B. Hopkins and O. C. Funderbunk) : 



Canavalia eocenica Berry? 



Lygodium binervatum (Lesquereux' Berry. 



Nectandra pseudocoriacea Berry? 



The following were sent in by the last-named 

 collectors from the Butler (or West Point) 

 salt dome, in the eastern part of Freestone 

 County, near Trinity River, 6 miles northeast 

 of Oakvdle, Tex.: 



Mespilodaphne coushatta Berry? 

 Palmocarpon butlerensis Berry. 

 Proteoides wilcoxensis Bern-. 

 Sophora repandifolia Berry? 

 ('alatoloides eocenicuni Berry. 



The following localities in central and south- 

 western Texas deserve some special comment, 

 as no collections have heretofore been made 

 from them and they show conclusively that 

 the Carrizo sandstone is of upper Wilcox age, 

 but that it is in the nature of a lens which 

 becomes thinner toward the Rio Grande, where 

 its upper part is replaced by more typical 

 and more argillaceous Wilcox beds that also 

 carry characteristic fossil plants. 



Fossil plants were reported by Baker from 

 the Elmendorf clay pit, south of San Antonio, 

 in Bexar County. This pit was not being 

 worked in 1921 and was partly full of water, 



about 25 feet of grayish laminated sandy clay 

 with local more argillaceous and darker lenses 

 carrying leaves being all that was exposed. 

 These leaves were poorly preserved, and the 

 only species recognized are Ficus mississippi- 

 ensis (Lesquereux) Berry, Nectandra sp., and 

 Sapindus linearifolius Berry. The manager 

 of the Elmendorf plant informed me that the 

 clay formerly mined came from the flooded 

 part of the pit and was full of impressions of 

 leaves. 



The Wflcox is well exposed along Nueces 

 River in Zavalla County. Fossil plants were 

 collected from the right bank 1 mile below the 

 Pulliam ranch house. The following species 

 are represented: 



Anona ampla Berry. 

 Anona eolignitica Berry. 

 <\ pontes sp. Hollick. 

 Oreodaphne obtusifolia Berry. 

 Sabalites grayanus Lesquereux. 

 Sapindus linearifolius Berry. 



Sandy lenses contain many Sabalites, some of 

 large size. One rachis of this species observed 

 was 2\ inches in diameter at one end and 4 

 inches at the other. These species indicate a 

 late Wilcox age and show the transgressive 

 character of the beds, as the Midway appears to 

 be absent on the Nueces, the Wilcox resting on 

 the Cretaceous and not far above the con- 

 spicuous reef of Ostrea cortex just above the 

 San Antonio, Uvalde & Gulf Railroad bridge. 



From Story's ranch to La Pryor crossing 

 there is a long exposure of typical Wilcox beds, 

 especially along the left bank of the Nueces for 

 about 2 miles above the crossing. Fossil 

 plants are abundant but so poorly preserved 

 that no collections were made, although several 

 \Vilcox species were recognized. 



From the crossing southward the Carrizo 

 sandstone is exposed. At an outcrop in a 

 deep arroyo along the left bank 1^ miles south 

 of the crossing there is an exposure of about 30 

 feet of buff heavily bedded and prominently 

 cross-bedded sand. At the base of this sand 

 3 to 4 feet of a small brownish clay lens is 

 visible. This lens, which is stratigraphically 

 above the ferruginous quartzite sand exposed 

 at the crossing, is full of leaves. The follow- 

 ing species, which indicate upper Wflcox age, 

 were collected: 



Banksia puryearensis Berry. 

 Eugenia grenadensis Berry.
