Cedrela ODOKATIFOLIA Beny, n. sp. 

 Plate LVII, figure 7. 



Deacripiion. — Leaflets large, elongate-ovate 

 in general outline, the base abruptly pointed, 

 inequilateral, and the tip extended, gradually 

 nan'owed, and eventually bhuitly pointed. 

 Lengfli alxuit 1.3 centimeters. Maximmu 

 width, in tlie lower lialf of tiie leafkit, about 

 2.2.5 centimeters. Margins entire, somewhat 

 irregularly curved. Texture subcoriaceous. 

 Midrib stout and proniinent proximad, bc^coni- 

 ing thin in the tip of the l(\if. Secondaries 

 numerous, subopposite to alternate; inore than 

 20 pairs diverge from the midrib at wide angles, 

 averaging about 60°. They are regularly 

 curved and cainptodrome. Tertiaries obsolete. 



This well-marked species of Cedrela is very 

 much larger than the other three Wilcox spe- 

 cies, with which there is no danger of confusing 

 it. Among existing species it is very close to 

 the AntiUean Cedrela odorata Linne, which 

 resemblance has suggested the name of the 

 fossil species, whose leaflets ai'e somewhat nar- 

 rower than those of the existing species. It is 

 practically identical with an unnamed existing 

 species of Cedrela figured by Ettingshausen.'

Genus VANTANKA Aublet. 



Vantanea wiLCoxiANA Berry, n. sp. 



Plate LIV, figure 6. 



Description. — Leaves small, broadly lance- 

 olate and slightly inecjuilateral in generiJ out- 

 line, widest near the middle, margins full and 

 incurved to the narrowed but obtusely pointed 

 tip and to the decurrent base. Length about 

 5 centimetei-s or slightly more. Maximum 

 width about 2 centimeters. Margins entire. 

 Texture coriaceous. Petiole .short and stout, 

 not produced beyond the decurrent limbs of the 

 lamimx. Midrib stout and ligneous, becoming 

 thin distad, not especially prominent, somewhat

flexuous. Secondaries thin but prominent, 

 about nine subopposite to alternate pairs, 

 diverging from the midrib at angles of 4.5° to 

 5.5°, pursuing a rather straight course until 

 they reach the marginal region, where they 

 curve upward in a brachiodrome manner. 

 Tertiari<'s well marked, comprising some 

 branches from the midi'ib parallel with the 

 secondaries, curved transverse nerviUes, and 

 finer connecting nervillcs, forming ojien, isodi- 

 ametric, four or five sided meshes. 



This species is correlated with the genus 

 Vantanea, which contains five or six existing 

 sjiecies in Brazil and Guiana, the one most 

 similar to the fossil being I antanea panicuJata 

 Urban. The family llumiriacea3 is much 

 reduced in the modern flora and comprises but 

 3 genera and about 20 species of shrubs and 

 trees, which witii the exception of one species 

 of West Africa are confined to luu-thern South 

 America.

Genus BANISTERIA Linne. 



Banisteria pseudolaurifolia Berry, n. sp. 



Plate.? LVI, figures G and 7, and CX, figure.s 1 and i. 



Description. — Leaves of variable size, ovate- 

 lanceolate in outline, the apex narrowly pointed 

 and the base broadly pointed. Length ranges 

 from 8 to 12.5 centimeters. Maximum width 

 ranges from 2.4 to 4.8 centimeters, in the basal 

 half of the leaf. Margins entire, full, and 

 rather evenly rounded; toward the tip they 

 may recurve slightly and the tip may be 

 slightly extended. Petiole stout, generally 

 curved, about 1 centimeter in length. Midrib 

 stout. Secondaries thm, 9 or 10 opposite to 

 alternate pairs, somewhat irregularly and 

 widely spaced; they branch from the midrib at 

 wide angles, averaging about 60°, curving 

 upward, camptodrome. Tertiaries largely ob- 

 solete, arching in the marguial region and form- 

 ing rather open, mostly polygonal, meshes in- 

 ternally. Texture coriaceous. 



This species is characteristic and rather 

 common in the upper part of the Mississippi
