10000 pcd. alt., leg. T. Kawakami et U. Moei, Nov. 1906, (No.

The present plant is originally described by myself as a 

 variety of P. elliptica Nutt. On examining carefully the leaves 

 with im.pressed veins and most minute seeds, I have thought it 

 better to regard the plant as specifically distinct from that species.
