DESCRIPTION OF SPECIES. 81 



the type of nervation is the same for these leaves, ])eiiii»- that of the pal- 

 mately triuerved section of the geuus. Tlie petiole is LS™'" long, thick and 

 mixch enlarged at the base.

Ficus PRvECURSoR, sp. nov. 

 PI. XLIX, Fig. 5. 



Leaves of medium size, long-petioled, enlarged at the middle, con- 

 stricted and taper-pointed above, narrowed to the base, entire; midrih 

 strong, precurrent; secondaries numerous, parallel, curved, camptodrome; 

 nervrlles distant, simple or rarely branching at the middle. 



There are two leaves of this species. The one tigured is 7"'" long witli 

 a petiole preserved which is 1"" long, 3.5"'" broad at the eidarged part (the 

 middle), and has nine or ten pairs of secondaries at an angle of divergence 

 of 40°. The other leaf is smaller but of the same form ; its pedicel is 

 broader than the midrib, evidently long but also broken 1*"" below the base 

 of the leaf 



The leaves resemble those of F. pidchen-ma Sap. (Etudes, vol. 1, p. 

 (S6, PI. VII, Fig. 2), Ijeing less inequilateral at the base, more abruptly con- 

 stricted below the less sharply pointed acumen. Saporta compares his plant 

 to some species of tropical Asia, especially F. tenax of Timor.

Ficus Krausiana Heer. 

 PI. L, Fig. 5. 



Leaves large, subcoriaceous, entire, lanceolate, gradually attenuate 

 upward from below the middle in passing to a blunt apex (destroyed) and 

 downward to a thin, short petiole; midrib comparatively narrow ; secon- 

 daries thhi, oblique, running straight from the midrib to near the borders, 

 where they abru})tly curve, following them in long, flat bows. 



The species is closely allied by some characters to F. Berthoudl, but 

 more distinctly by others to F. Krausiana Heer (Flora von Moletein, p. 15, 

 PI. V, Figs. 3-6). From F. Berthoudi it differs in the thick, coriaceous leaves, 

 apparently blunt at apex; the secondaines straight from the base to near the 

 borders, separated by a simple intermediate tertiary. From F. KrausUina
