The genus has not been heretofore recognized in America in 

 any deposits of Tertiary age. Several species were described 

 and figured from the middle Tertiary of the Old World, but 

 none of these could by any possibility be confused with our spec-

to them, is necessary. The genus Passiflora, as it exists to-day, 

 is mostly tropical and semitropical in its distribution; but the 

 species P. incaniata, which our specimen appears to resemble 

 most closely, is native as far north as Virginia and Missouri, and 

 is said to be hardy, in cultivation, somewhat further northward.
