FICUS, Linn. 



Ficus asimiiiiB folia, sp. nov. 



Plate LVI, Figs. 1-3. 



Leaves of medium size, coriaceous and polished on the surface, oval-oblong, 

 rounded and contracted at the apes into a short obtuse acumen, rounded and narrowed 

 at the base to a long vei-y thick petiole; secondary nerves few, distant, deeply marked, 

 caniptodrome, with few outside branches. 



The leaves vary from 9 to 14 centimeters long and 4 to 7 centimeters 

 broad; tlie borders are very entire ; the nerves, very deeply impressed into 

 the thick substance of the leaves, diverge from the midrib at an angle of 

 50° or 60°, first straight, then much curved, especially toward the borders, 

 which they follow in simple bows. The medial nerve is gradually thicker 

 downward from the apex, and passes to a long very thick pedicel measur- 

 ing, in fig. 1 (the smallest leaf) , 3 millimeters at the base of the leaf and 

 4 where it is broken, 3i centimeters lower. 



This leaf has somewhat the appearance of a Juglans and also, especially 

 by its thick substance and its contracted apex, of a Magnolia, but the great 

 thickness of the pedicel, the direction of the lateral nerves, refer it to a 

 species of Ficus related to F. f ApocynophjllumJ penninervia, Ung., as 

 represented in Ett., "Beitr. zur. FL v. Radoboj.," p. 47, pi. ii, fig. 1.

 Persea princeps, Schp., "Pal. V6get.," ii, p. 831. 



Leaves coriaceous, broadly lanceolate or ellipticallanceolate, narrowed upward 

 to an acute point or a short acumen and downward to the petiole; lateral nerves thin, 

 numerous and subparallel, joining the medial nerve nearly at right angles, campto- 

 drome. 



This leaf,'15 centimeters long, 3 centimeters broad in the middle, has 



all the characters of the species as it is described by the authors, and is, 



though larger, similar to Ludwig's fig. 6, pi. xl, I. c, differing, however, by
