Genus IVIIMUSOPS Linnfi. 



MiMUSops siEBEKiFOLiA Bcrrv, n. sp. 

 Plate X('IX, figure 2. aiul (', (i;j;ui-c :>. 



Description. — Leaves elonsjate-eUiptical in 

 outliiie, the apex broadly rounded, more or less 

 retuse in some spcH'inu'us, and the iiase only 

 slightly narrowed, rounded, or wide and bluntly 

 pointed. Margins entire and full, sonu'what 

 revolute, as indicated by the impression they 

 make on the clay and their slightly undulating 

 appearance in specimens that show the upper 

 surface of the leaf, like the one figured. Tex- 

 ture very coriaceous. The lamina is generally 

 broken near the base so tluit^ the petiole, which 

 must have been long anil stout, is missing. 

 Somewhat variid)le in size, averaging about 9 

 centimeters in length by 2h centimeters in 

 maximum width, about halfway l)etweon the 

 apex and the base of the synmu^trical leaves. 

 An extra large specimen is 12 centimeters long 

 and 3.5 centimeters in niaxinuun width. 

 Midrib stout and straight, channeled above and 

 more or less prominent on the lower surface of 

 the leaf. Secondaries about 10 sul)opposite to 

 alternate pairs; they branch from the midrib 

 at angles ranging from 40° to 6.5° and curve 

 vipward, ultimately camptodrome. The ter- 

 tiaries form rather large isodiametric, five or 

 six sided meshes. 



This fine species is not unconnnon at Puryear 

 and is scarcely to Ix; distinguished from several 

 of the existmg species of Mimusops, the specific 

 name being given in allusion to its resemblance 

 to Mimusops sieheri A. Do CandoUe, of the 

 Florida Kej's and Bahama Islands, a small tree 

 of the strand flora, like so many of the existing 

 species of Sapotacea\ The species now mider 

 consideration may also be compariul with 

 Mimusops spectahilis Pittier of the littoral for- 

 est of Costa Rica or w-ith the Brazilian ^fimu- 

 sops longifolia. It may l)e also conijiared with 



certain specic^s of the doseh^ allied genus 

 Sideroxylon Liniu'. Capparis j(imaic( nsis 

 .I.-ic(|uiii is also \ci-y similar in outline and 

 texture. 



Tii(^ genus Minuisops contains 30 or 40 exist- 

 ing s])(^(•ies widely distributed in the Trojiics of 

 l)oth hemisphenw. Several fossil specic^s have 

 ])een described, and comparisons may be made 

 with th(^ Oligocene species Mimusops tertiaria 

 Ettingshausen ' from southern Europe (Car- 

 nioln ) and So jiofacifes mimusops Ettingshausen- 

 fi'oni tlicTvi'ol. Bolli arc less elongated, and 

 though sinular in tlunr geniu'al I'acies are less 

 typical of Mimusops than the present species. 

 In tlu^ Wilcox flora Laguncularia preracemosa 

 Berry has somewhat similar leaves; they are, 

 however, relatively shorter and have a difl'erent, 

 more or less obsolete venation and a difl'erc^nt 

 ti'xture. They are no more readily confused 

 than the leaves of the existing Laguncularia 

 ntcemosa Gaertiu'r and Mimusops sieheri A. De 

 CandoUc. 



Occurrence. — Lagrang(> formation (in beds of 

 Wilcox age), Purvear, Henry County, Tenn. 

 (collected by E. W. Berry).
