about 2.1 cm. long. The leaf is trilobate, five-nerved; the lateral 

 nerves diverge from the top of the petiole ; the two lowermost nerves 

 are thinner than those passing to the lobes. The base is truncate and 

 rounded, declining to the petiole. The lobes are about equal, obtuse 

 or apiculate, entire, separated by rather broad sinuses, which reach 

 about half-way to the midvein.
