Sainndus aiigHsti/oIii(s. Losquereux, U. S. Nat. Mas. 

 Proc, vol. 11, p. 24. 188S. 



Description. — Leaflets witli relatively long 

 petiolules, lanceolate-falcate and slightly in- 

 equUateral in outline. Length ranges froni 6 

 to 8.5 centimeters, averaging about 6.6 centi- 

 meters. Maximum width, in the lower half of 

 the leaflet, ranges from L3 to L6 centimeters. 

 Apex gradually narrowed and sharply pointed. 

 Base more shortly and broadly pointed. 

 Margins entire, in some specimens slightly 

 irregular, rounded and full basally, rather 

 straight distad. Texture sul)coriaceous. Pe- 

 tiolules stout, curved, prominent on the lower 

 surface of the leaflet. Secondaries thin, about 

 eight suboppositc to alternate pairs, diverging 

 from the midrib at angles of about 45° and 

 curving upward somewhat irregularly in some 

 individuals, and camptodrome a consideralde 

 distance from the margins. Tertiaries distinct 

 in most specimens; they form marginal arches 

 and internally large pentagcmal meshes. 



This species resembles the smaller leaves of 

 the Fort Union Sajnndus affinis Newberi-y, but 

 is less inequilateral and more regularly falcate. 

 It is also comparable witli the Florissant 

 Sapindus angustifolius Lesquereux but is readily 

 distinguishable, .\mong the Wilcox sjiecies of 

 Sapindus it is approximately the same size as 

 Sainndus mississippiensis Berr\- and Sapindus 

 eoligniticus Berry. It jdiffers from Sapindus 

 mississippiensis in being wildest below the 

 middle and in iiaving a straight-sided nar- 

 rowed ti]), a broader base, and a long ])etiolule. 

 It differs from Sapindus eolignitiea in l)eiug 

 abruptly pointed distad ami not rounded 



jiroximad, in its less coriaci'ous texture, rela- 

 tively narrower form, more asceiuling secon- 

 daries, and longer petiokde. 



It is very similar to the smaller leallets of 

 several existing American species. A specimen 

 of this species was collected at WiddifTe, and 

 a rather large leaf which appears to be refer- 

 able to it from northwestern Louisiana was 

 identified by Lesquereux as Sapindus angusti- 

 folius (U. S. National Museum No. 2600*). 

 A specimen was collected at Wickliffe, Ky., 

 many years ago by R. H. Loughridge (U. S. 

 National Museum No. 2571) and four complete 

 specimens were collected recently from this 

 same outcrop by L. C. GlenTi. It is aljundant 

 in the clays at Puryear, Tenn., and survives 

 the Wdcox, being found in the List)on forma- 

 tion of the Claiborne group near Newton, Miss.

Sapixdus eoligniticus Berry, n . sj). 

 Plates LXVII, figures 1-3, and CIX, figure 2. 



Description. — Leaflets relatively sliort and 

 wide, ovate in general outline, only slightly fal- 

 cate. The al)ruptly acuminate tip is rounded 

 in some specimens and the base is rounded 

 and more or less inequilateral. Length ranges 

 from 5 to 7.5 centimeters. Maxinmm width, 

 in the lower half of the leaflet, 1.:! to 2 cen- 

 timeters. Margins entire, slightly and faintly 

 undulate in some specimens, incurved slightly 

 at the tip, full and rounded below, broadly 

 on one side of the midrib and narrowly on 

 the other side. Petiolules short, stout, and 

 curved, not over 3 millimeters in length, which 

 is only about half the lengtli of the petiolules 

 of Sapindus formosus Berry. Midrib less stout 

 tlian in Sa pindus formosvs, straiglit or slightly 

 curved distad, prominent on the lower surface.
