the middle, about A.'lo ceiitimeters. Margins 

 entire, somewhat irrcguhirly curved. Texture 

 coriaceous. Petioh> extremely stout, curved, 

 about 1.25 centimct(>rs in length, S millimeters 

 in diameter at tiie enlarged base. Midrib stout 

 throughout, broad and flat, curved. Sec- 

 ondaries stout, numerous, subparallel, more 

 widely spaced in the upper half of the leaf; 

 about 10 subopposite to alternate pairs diverge 

 from the midrib at angles of about 60° to 65°, 

 pursuing a rather straight course to the margi- 

 nal region, where they ai-e camptodrome. Ter- 

 tiaries well marked, obliquely percurrent. 

 Areolation rectangular. 



This species differs markedly from the other 

 Wilco.x species referred to this genus, suggest- 

 ing some of the Sapotaccre in its general ap- 

 pearance. It has, however, the venation of the 

 Anacardiacete and may be compared with 

 existing genera of that famdy, especiiiHy the 

 genus Anacardium Linne, which comprises 8 

 species in tropical America. The present spe- 

 cies is apparently rare. 



Occurrence. — Lagrange formation (in beds of 

 Wilcox age), Puryear, Henry County, Tenn. 

 (collected by E. W. Berry). 



Collection. — U. S. National Museum. 



Anacarditfs minor Berry, n. sp. 



Plate LVII, figure 4. 



Description. — Leaves or leaflets relatively 

 small, obovate in general outline, the tip 

 broadly rounded, and the base broadly cu- 

 neate. Length about 2 centimeters. Maximum 

 width, midway between the apex and the base, 

 about L5 centimeters. Margms entire, some- 

 what undulate. Texture subcoriaceous. Peti- 

 ole short and much enlarged, about 2 centi- 

 meters or slightly less in length. Midrib rather 

 stout, prominent, nearly straight. Seconda- 

 ries thin, relatively prominent: 5 or 6 suboppo- 

 site pairs diverge from the midrib at angles of 

 about 50° and pursue a nearly straight course 

 to the margin, where they form single flat 

 camptodrome arches which simulate marginal 

 hems. Tertiaries thin', mainly percurrent. 

 Areolation predominantly quadrangular. 



The present species in its size, outline, and 

 marginal venation is clearly differentiated from 

 the other members of the WUcox flora and as 

 clearly allied with existing meml)ers of the 

 Anacardiacese. It is apparently rare. 



Occurrence. — Lagrange formation (in Ix-ds of 

 Wilcox age), Puryear, Henry County, Tenn. 

 (collected by E. W. Berry). 



Collection. — U. S. National Museum. 



Anacardites grevilleafolia Berry, u. sp. 



PkUcs LVII, figure .5, and LVIII, figure .5. 



Description. — Leaflets small, lanceolate in 

 outline, the apex sharply pointed and the base 

 similarly pointed. Length ranges from 2.5 to 

 4.5 centimeters. Maximum width, slightly be- 

 low the middle, ranges from 7 to 11.5 milli- 

 meters. Petiolule short and stout, about 1.5 

 or 2 millimeters in length. Midril) very stout 

 and prominent. Secondaries thin, numerous, 

 close set, diverging from the midrib at acute 

 angles less than 45°. Those in the lower half 

 of the leaflet are curved and ascend subparal- 

 lel with each other and with the lower lateral 

 leaf margins: those in the upper part are less 

 ascending and subtend wider angles: all are 

 camptodrome. Tertiaries obsolete. Margins 

 entire. Texture coriaceous. 



This is the smallest species of Anacardites 

 known in the Wilcox flora and it is thorougldy 

 distinct from the other species, Anacardites 

 metopi folia Berry being the only one that ap- 

 proaches it at aU, and the two are not close. It 

 is something like Rims palseopliylla Saporta ' of 

 the Sannoisian of France, but the resemblance 

 is not close enough to demand extended com- 

 ment. It is also more or less like several 

 described Tertiary species usually referred to 

 Rhus. 



Occurrence. — Grenada formation, Grenada, 

 Grenada County, Miss, (collected by E. N. 

 Lowe and E. W. Berry). Lagrange forma- 

 tion (in beds of Wilcox age), Puryear, Henry 

 County, Tenn. (coUected by E. W. Berry).

Anacardites metopifolia Berry, n. sp. 



Plate LVIII, figure 7. 



Description. — Leaflets small, ovate in general 

 outline, lateral margins full rounded, narrowing 

 upward to an obtuse tip, basal margins rounded, 

 and base very broadly cuneate or rounded. 

 Length about 4.5 to 5 centimeters. Maximum 

 width, toward the base of the leaf, about 2 

 centimeters. Margins entire. Texture cori-
