 Most of the species are coastal forms of (iifrereiit 

 hahitats. Guppy mentions (pinntities of seeds 

 of Aiiona ■paludosa in the (h'ift of the Guaya- 

 quil River estuary, many of them in a germi- 

 nated condition. Safford mentions that Anona 

 reticulata is readily naturalized in Guam and 

 other parts of the oriental Tropics, where it 

 occupies a prominent place in the send) of the 

 injier beaches. It seems probaljle that this and 

 the other Wilcox species of Anona inhabited 

 the low shores of coastal lagoons or the lower 

 and more or less swampy reaches of the tribu- 

 tary streams. No seeds referable to Anona 

 have been discovered in the clays of the Wilcox 

 group, but Lcsc(uereux many years ago i-e- 

 corded seeds from Oxford, Miss., which he 

 described as Asimina leiocarpa. 



Occurrence. — Lagrange formation (m beds 

 of Wilcox age) , Puryear, Henry Comity, Tenn. 

 (collected by E. W. Beny) ; bed of M()])ley 

 Creek, 4 miles southwest of Trenton, Gibson 

 County, Tenn. (collected by Bruce Wade).

Anona eolignitua Beny, n. sp. 

 riatn XLII, ligures 2-}. 



Description. — Leaves of medium size, oblong- 

 el'iptical in general outline, the apex and base 

 roimded or bhuitly pouited. Length ranges 

 from 10 to 16 centkueters. Maximum width, 

 ia the middle part of the leaf, ranges from 4.25 

 to 5.5 centimetrere. Margms entire, very 

 shghtly undidate on some specimens. Textm-e 

 coriaceous. Short and stout, enlarged proxi- 

 mad, about 6 millimeters m length. Midrib 

 stout, prominent on the lower sm-faco of the 

 leaf. Secondaries stout but immersed in the 

 leaf sid)stance, about 10, evenly S])aced, oppo- 

 site to alternate pairs, divergmg from the mid- 

 rib at angles of 70° to 80°, cm-vmg regularly 

 upward and camptodrome. Tertiaries largely 

 obsolete. 



This species is smaller, relatively more elon- 

 gated, and more robust than Amnia- ampki 

 Berry. It is nuich like Anona wilcoxianu B<'rry 

 and may possibly be a variimt of that species, 



although it is mor(> narrmvod distad, has loss 

 prominent venation, and in spile of its lai'^or 

 size lias a much slenderer midiil). 



Occurrence. — Lagrtmge formation (in lieds of 

 Wilcox age), Pmyoai-, Henry County, Temi. 

 (collected by E. W. BeiTy).- Wilcox group, 

 sec. 2S, T. 13 N., R. 12 W., 4A miles and 5 

 miles southeast of Naborton, De Soto Parish, 

 La. (collected 1>y G. C. Matson and O. B. 

 Hopkins).

Anona ampla I'xnr 



y, n. sp. 



Plates XXXIX, figure 1; XL, liguri' 1; and XLl. ligure 3. 



Description,. — Leaves relati\ely large, ellip- 

 tical in geueial outlme, ranging from 17 to 22 

 centimeters m length by about 8 to 8.5 centi- 

 metei-s m maximum width, at or shghtly below 

 the middle. Ai>ex naiTowed, roimded or 

 l^hmtly short pomted. Base romidetl. Mar- 

 gms entire. Leaf substance thin for so large a 

 leaf. Petiole stout, not preserved for its whole 

 length, at least 1 centimeter long. Midrib 

 stout, less so than m Anona wilcoriana Berry, 

 and nan-ower as well as rounder. Secondaries 

 relatively thin, about nine subopposite to alter- 

 nate, rather evenly spaced pairs, diverging 

 from the midrib at angles of 70° to 80° and 

 ciB-vmg regularly upward, camptoclromo in the 

 marginal region. Tertiaries of a similar char- 

 acter to those of the precedmg species but very 

 thin and visible only with magnification. 



This is the largest of the throe Wilcox species 

 of Anona. It is less robust in texture and 

 venation than either of the others, both of 

 which it greatly resembles m genersil fonn and 

 character of venation. It appears to be the 

 least common of the three and may possibly 

 represent a variant of Anona eolignitica Beny 

 due to especially favorable conditions of growth 

 such as a shady humid habitat.
