Smilax Wardii, n. sp. Plate xm, fig. 1. 



Leaf long, linear-lanceolate, gradually narrowed above to an acute 

 point, hastate sagittate at base, 5 to 7 nerved from the base of the me- 

 dial nerve. 



The blade of leaf is about 14 cm long, 2 cm broad below the middle, with 

 two pairs of secondaries or lateral nerves emerging from the base, the 

 inner more distinct at an acute angle of divergence, passing up in the 

 middle of the areas, parallel to the midrib and aerodrome, the outer 

 pair emerging from the base nearly at right angles dividing at the mid- 

 dle in two branches, the one directed upward from which depends the 

 the outer, thin secondaries, which follow close to the borders, being 

 gradually effaced above, the other descending into the auricle by branch- 

 lets, there curving down and around, anastomosing in following the 

 borders, with tbin nervilles emerging from the base of the midrib. The 

 areolation is made of thin nervilles oblique to the secondaries and 

 crossing obliquely in rhomboidal meshes. 



Eelated by its prolonged rounded auricle to the numerous sagittate 

 species of ftmilax, the leaf differs from all by the very long linear Ian-, 

 ceolate blade, the obtuse auricles descending 2 0M below the base of the 

 midrib, diverging from each other at an angle of 55 to CO degrees.
