No. 2388. TERTIARY FOSSIL PLANTS FROM VENEZUELA— BERRY. 573 



subcoriaceous. Length about 4 cm. Maximum width about 3.2 cm. 

 Midrib thin, but prominent. Secondaries immersed; 9 or 10 camp- 

 todrome pairs diverge from the midrib at regular intervals, at angles 

 of about 55 to 60°, pursue a curved ascending subparallel course, and 

 are camptodrome in the marginal region. Tertiaries obsolete. 



This species is based upon the single specimen figured, and because 

 of this paucity of material it is referred to the form-genus Legumino- 

 sites. It has been compared with the somewhat similar forms in 

 genera likely to occur in this region, such as Mirnusops, Laguncularia, 

 Sophora, Cassia, Clirysobalanus, etc. In size, texture, and venation, 

 as well as in its intangible facies, it suggests the Leguminosae, among 

 which there are a considerable number of analogous or homologous 

 forms. Without being able to decide upon its generic affinity, I have 

 suggested, in the specific name proposed, its possible relationship with 

 Entada, which is represented by a fossil seed at Mesa Pablo in this 

 region and at a not very different horizon. 



The specimen comes from the sandy clays, 2\ miles northwest of 

 La Salvadora.

Leaves pinnate. Leaflets sessile or subsessile, small, elliptical in 

 general outline, with a bluntly pointed apex and base. Margins entire, 

 slightly revolute. Texture subcoriaceous. Length about 4 cm. or 

 less. Maximum width, midway between the apex and the base, 

 2 cm. or less. These leaflets are slightly inequilateral, one side (the 

 proximal) of the lamina being 1 to 2 millimeters narrower than the 

 other. The midrib is stout, somewhat curved, and prominent on the 

 under side of the leaflet. The secondaries are fairly stout, numerous, 

 approximately equally spaced, and prominent; they diverge from the 

 midrib at angles between 60 and 70°, pursue subparallel and almost 

 straight courses, and are abruptly camptodrome close to the mar- 

 gins. The tertiaries are relatively stout and mostly percurrent, 

 although there are some nervilles from the midrib that run sub- 

 parallel with the secondaries part way toward the margins. 



The single specimen upon which this species is based came from the 

 clay outcrop at Betijoque, and shows parts of five leaflets, and from 

 their disposition it appears that their arrangement was alternate, 

 Of these the central one in the accompanying figure is much the
