material the upper half of the leaf is narrow and is produced as a long, 

 slender, often recurved tip, which is one of the characteristic features of 

 the species. This tip is strictly comparable with the " dripping points " 

 developed on various leaves in the modern tropics where precipitation is 

 heavy. 



Ficus daphnogenoides is a widespread and common form ranging from

 west Territory to Kansas and Nebraska in the Western Interior.

Description. Leaves ovate in outline, 8 cm. to 13 cm. in length by 

 4 cm. in width, petiolate. Apex extended, acute. Base rounded or some- 

 what descending. Margins entire. Principal veins three, from the base, 

 the midrib being the stoutest and slightly flexuous. The lateral veins 

 diverge at angles of about 45 and curve upward, traversing somewhat 

 more than the basal half of the leaf and connecting with branches from 

 the lowest pair of camptodrome secondaries, of which there are several 

 alternating pairs branching from the midrib at wider angles. The laterals 

 give off on the outside eight to ten camptodrome veins. Quadrangular 

 areoles formed by nearly straight transverse nervilles fill all the inter- 

 vening space.
