Description. — Leaflets relatively large, obo- 

 vate, and somewhat falcate in general outline. 

 Apex not ]>roduced, inequilateral, l)luntly 

 pointed. Base inequilateral, ])(>intcd, and some- 

 what decurrent. Length about 7 centimeters. 

 Maximum width, near the middle of the leaflet, 

 about 3.4 centimeters. Margins tMitire, ratiier 

 evenlj' rounded. Texture subcoriaceous. Petio- 

 lule missing. Midrib stout, prominent, and 

 ciu'ved. Secondaries rather stout, about seven 

 sul)opposite to alternate ])airs; they diverge 

 from the midrib at angles of al)Out .50° to 70°, 

 more open on the side of the midrib where 

 the lamina is widest: they are subparallel and 

 rather straight until they reach the nuirginal 

 .region, where they curve upward and are 

 camptodrome. Tertiaries well marked, mostly 

 forking and inosculating, forming an open, 

 mostly live-sitletl areolati(jn. 



This species is based on one of the two forms 

 from the Wilcox group of Jjouisiana which are 

 referred l)y llollick to JugUins ruyosa Lescjue- 

 reux,' a form from the lower Eocene of the 

 Rocky Mountain province that is in general 

 much larger, much more elongated, and has a 

 broader base. 



The present species is much broader than 

 Sajnndus Icnowltoni, S. niisslssippicnsis, S. lin- 

 earifolius, S.formosus, and .S'. eoligniticus of the 

 Wilcox flora. It is mucli shorter and broader 

 than tlie two large species, S. hentoncnsis and 

 S. oxfordensis. It is not so large as the leaflets 

 of S. jiscudaffinis.hntis more <'lliptical in out- 

 lin<^, more pointed at the base, and difl'crs in the 

 details of the tertiary venation. 



Occurrence. — Wilcox group, one-fourth mile 

 above Coushatta, Red Rivcir Parish, La. (col- 

 lected by A. C. Veatch).

Dfxcri ption. — Leafltits largo, elongate ellip- 

 ticid-lanceolate in outluKt, fidcate. slightly ine- 

 (|uilaterid, the a])ex pointed and the base mark- 

 edly inequilateral, rounth^d on one side and 

 narrow and straight on the other side. Length 

 al)()ut i) <«Mitimoters. Maximum width, in the 

 middle part of the letdh^t, about l.S centimeters. 

 Margins entire. Petiohde short and stout, 

 tumid, a])out '-i millimeters in length. Midrib 

 stout and curved. Secondaries thin, about 

 eight subopposite pairs, diverging from the 

 midrib at wide angles, a])out 50°, curving reg- 

 ularly upward, subparalUil and camptodrome. 

 Tertiaries mostly ol)solete. 



This well-marked species is sparingly repre- 

 sent<'d in tlie coUei-tious from Oxford and Gre- 

 nada. It is clearly unlike the other Wilcox 

 species of Sapindus. It approaches closest to 

 Sapimlus p.'ieudtiffinis Beriy but is smaller, ha^ 

 less regularly curved margms or pointed ends 

 and fewer secondaries, and the tertiary vena- 

 tion is less prominent and different. It is en- 

 tirely distinct from Sajyindus hentoneims Berry 

 as well as from the other Wilcox species, which 

 have much smaller leaflets. It is not unlike 

 the Fort Union species Sapiti^Jus grand ifoli oh i.s 

 Ward and the larger leaflets of Sapindu.s ajfinis 

 Newberry. It is like a number of existing 

 species, uicluding Sdpindu.s ■sajionaria Linne of 

 the American tropical and subtropical strand 

 flora, and is especially like the larger leaflets of 

 Sapindus marginatus Willdenow, which ranges 

 along the Florida coast northward as far as St. 

 Jolms River and Cedar Keys.
