LESQUEREux] NEW TEETIAEY FOSSIL PLANTS. 315 



The species may be different from the European one bearing this 

 name, but it appears to diiier only by more open secondary veins. 



Habitat. — Green Eiver group, near mouth of White Kiver, Frof. 

 TF«i. Denton. 



31. LegtUminosites alternans, sp. nov. 



Leaflet lanceolate, narrowed to the sessile base (po;nt broken), appa- 

 rently ta{)eriug and acute ; borders entire ; secondary veins close, nu- 

 merous, fifteen pairs in a space of two and a half centimeters, with in- 

 termediate shorter tertiary veins anastomosing by crossing veiulets; 

 areolation obsolete. This leaf is comparable to a Dalheryia or a Podo- 

 goniuni by its nervation ; its form, especially the narrowed base, is com- 

 parable to Cassia. 



Habitat. — Near mouth of White Eiver, Prof. W. Benton. 



32. Sapinbus Dentoni, sp. nov. 



Leaves lauceolote, gradually narrowed to a long acumen, unequilat- 

 eral and rounded at base to a short petiole, entire or slightly undulate, 

 thick; secondary veins close, parallel, diverging forty to fifty degrees, 

 thick, straight to the borders, where they abruptly curve, and which they 

 closely follow. 



Species allied to Sapindus falcifolius, Heer, but remarkably distinct 

 from this and other congeners, by the thick, close, lateral veins straight 

 to the borders, where they curve so abruptly that they appear at first 

 sight as craspedodrome. The areolation is of the same character as 

 that of S. falcifolius. 



Habitat. — Green Eiver group, near mouth of White Eiver, Prof. W. 

 Benton. 



33. LOMATIA MICEOPHTLLA, Sp. TIOV. 



Leaves very small, thick, coriaceous, linear-lanceolate, gradually nar- 

 rowed to a point, and in the same degree to the base ; secondary veins 

 simple, thin, in an open angle of divergence, connected to a marginal 

 vein. We have two leaves of this fine species. It is comparable to 

 Lomatia firma^ Heer, of the Baltic flora, but very small and thick j the 

 surface mostly covered by a coating of coaly matter. 



Habitat. — Same locality as the former, Prof. W. Benton. 



A large number of fruits and seeds, considered under the name of 

 Palmacites, Carpolites, etc., have been figured for the Lignitic Flora. As 

 the characters of these organs cannot be represented by mere description, 

 they are not mentioned iu this short synopsis.
