the petiole, diverging at acute angles, the midrib running 

 straight to the base of the sinus, the laterals but slightly curved 

 in passing to the tips of the lobes. Secondaries remote, fine, 

 camptodrome. 



Passiflora is entirely a warm temperate or tropical type, and 

 while it is found in both Asia and Australia it is primarily 

 American and makes its greatest display in the tropics of 

 Central and South America. Perhaps 250 species in all have 

 been described. 



Fossil representatives of this genus are rare. In addition to 

 the present species two characteristic species are described by 

 Friedrich-^ from the much more recent Ligurian deposits of 

 Saxony.
