lesquereux.] NEW TERTIARY FOSSIL PLANTS. 315 



The species may be different from the European one bearing this 

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



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

 Win. Benton. 



31. LEGTJMrNOSITES ALTERNATES, sp. 1IOV. 



■ Leaflet lanceolate, narrowed to the sessile base (point broken), appa- 

 rently tapering 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 veinlets; 

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

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

 parable to Cassia. 

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



32. Sapindus Dentoni, sp. nov. 



Leaves lanceolote, 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 8. falcifolius. 



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

 Benton. 



33. LOMATIA MICROPHYLLA, Sp. HOV. 



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 Jirma, Heer, of the Baltic flora, but very small and thick; 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, Garpolites, etc., have been figured for the Liguitic Flora. As 

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

 they are not mentioned in this short synopsis.
