SHORTER CONTRIBUTIONS TO GENERAL GEOLOGY, 1922. 



In Professional Faper 91 I recorded 342 

 species of plants from the Wilcox. In Profes- 

 sional Paper 108-E, published in 1917, species 

 of Zamia and Nelumbo were added. The 

 present contribution includes additional plants, 

 but as a number of supposed species of Ficus 

 are now reduced to synonymy, the total addi- 

 tions amount to 9, making 353 as the number of 

 species now recognized in the Wilcox flora. 



The descriptions in the present paper include 

 both lauraceous and sterculiaceous woods, 

 also strikingly well preserved and charac- 

 teristic lauraceous fruits. Other novelties are 

 a liverwort (Marchantites,) the fern genus 

 Dryopteris, palm nuts, the genus Monocarpel- 

 lites (which helps to prove that the lignites of 

 Brandon, Vt., are Eocene and not Miocene), 

 an interesting fruit of the otherwise unrep- 

 resented family Icacinaceae, and a second 

 which is referred with some hesitation to the 

 family Anacardiaceae. 



The upper Wilcox plant-bearing bed in the 

 Grenada formation near Grenada, Grenada 

 County, Miss., is at the southernmost point at 

 which determinable fossil plants had been found 

 in the Wilcox in the eastern Gulf area. Much 

 interest therefore attaches to a small collection 

 made recently in southern Alabama by C. W. 

 Cooke and J. A. Gardner. The exact locality 

 is at the wagon bridge on Claybank Creek 1 

 mile west of Clayhatchee, Dale County. This 

 is about 300 miles southeast of Grenada and 

 east of the typical localities of marine Wilcox 

 beds. The matrix is a sandy brown clay, and 

 the contained leaves are poor and fragmentary. 

 Representatives of four different species are 

 recognizable, although but one of these is 

 determinable, and this represents a perfect 

 leaflet of Mimosites variabilis Berry. 



The following species are recorded from the 

 Spinks pit, near Paris, Henry County, Term. 

 The specimens occur in a gray plastic clay from 

 which the entire leaves can be washed and 

 mounted in balsam between glass, thus forming 

 very exceptional specimens: 



Monocarpellites perkinsi Berry. 

 Nectandra glenni Berry. 

 Oreodaphne salinensis Berry. 

 Sapindus mississippiensis Berry. 



The following are additions to the flora from 

 a locality 1 mile south of Grand Junction, 

 Tenn. : 



Sabalitee grayanus Lesquereux. 

 Oreodaphne puryearensis Berry. 



At the time of publication of Professional 

 Paper 91 the collections obtained 4 miles south- 

 west of Boydsville, Ark., were lost, and as they 

 had only received a preliminary study the list 

 of species from that locality was very incom- 

 plete. These collections have since received 

 careful study, which has shown that Ficus 

 denveriana should be omitted from this florule 

 and that the following species should be added: 



Anacardites puryearensis Bern'. 



Apocynophyllum mississippiensis Berry. 



Apocynophyllum wilcoxense Berry. 



Cinnamnmum oblongatum Berry. 



Coccolobis uviferafolia Berry. 



Cyperaeites sp. 



Engelhard t i a ettingshauseni Berry. 



Ficus mississippiensis (Lesquereux I Berry. 



Fieus pseudocuspidata Berry. 



Ficus puryearensis Berry. 



Hiraea wilcoxiana Berry. 



Juglans schimperi Lesquereux. 



Magnolia leei Knowlton. 



MyTcia vera Berry. 



Nectandra puryearensis Berry. 



Oreodaphne mississippiensis Berry. 



Palmocarpon luitlerensis Berry. 



Sapindus mississippiensis Berry. 



Ternstroemites eoligniticus Berry. 



These all serve to emphasize the late Wilcox 

 age of the Boydsville florule. 



At a locality near Jacksonville, in Pulaski 

 County, Ark., L. W. Stephenson collected the 

 following species, which prove the outcrop to 

 be of upper Wilcox age: 



Celastrus taurinensis Ward. 



Cordia'.' lowii Berry? 



Dillenites microdentatus (Hollicki Berry. 



Euonymus splendens Berry. 



Ficus harrisiana Tlollick. 



Marchantites stephensoni Berry. 



Nectandra cf. N. glenni Berry. 



Nectandra sp. 



i Ireodaphne obtusifolia Berry. 



In material from a gray plastic clay at 304 

 to 319 feet below the surface in a well at 

 Negreet, 9 miles southwest of Many, Sabine 

 Parish, La., I recognized the two following 

 Wilcox species: 



Pteris pseudopinnaeformis Lesquereux. 

 Simaruba eocenica Berry. 



The following plants were collected by O. M. 

 Ball at the Goss pit, half a mile east of Mans- 

 field, De Soto Parish, La. :
