Order Laurales 



Family HERNANDIACEAE 



Genus HERNANDIA Linnaeus 



HERNANDIA TONGI, new species 



Figure 30, c 



Leaves of medium to small size for this genus, ovate in outline, 

 with a broadly rounded base and an acuminate tip. Margins entire. 

 Texture subcoriaceous. Length 10.5 to 17 cm. Maximum width, 

 at or below middle, 4.5 to 9 cm. Petiole not preserved. Mid vein 

 stout and prominent on under side of leaf. Lateral primaries one 

 on each side, opposite, stout, and prominent, diverging from mid 

 vein at acute angles at a greater or less distance above its base, as- 

 cending and dying out subparallel to lateral margins one-half to 

 two-thirds distance to tip. Secondaries mediumly stout, alternate 

 to subopposite, three to five pairs, diverging from mid vein at angles 

 of 45° or less, ascending in regular sweeping curves, camptodrome. 



From outer side of lateral primaries there are numerous stout, 

 regularly and closelj^ spaced, camptodrome secondaries, which di- 

 verge at acute an.gles and are subparallel. Tertiaries well marked, 

 comj)rising closely spaced and mostly simple veins at right angles to 

 primaries and secondaries. 



This is a type of Tertiary leaf that has frequently been referred 

 to the genus Ficu.s, as in the case of the F. mississippiensis group of 

 the Eo€ene in the United States,^ but that probably is not related to 

 Ficus. It is also very similar to the leaves of entire Sterculias. 

 Several of these may profitably be compared with the modern species 

 of Hernandia. 



This species is present in the Miocene of the De Mares Concession 

 in the Magdalena Valley, Department of Santander, Colo^dibia. 



Occurrence. — La Victoria-Catanaja Road, about 2i^ kilometers 

 north of La Victoria, District of Miranda; Zapayari-El Plan Road, 

 iy2 kilometers south of Rio Grande, District of Bolivar, State of 

 Zulia. 



Type.— U.S.N.M. no. 39305.
