 2J in. wide, glabrous except on the midrib and veins beneath ; 

 midrib thick ; lateral nerves about 10 on each side, spreading, curving 

 upwards and uniting near the margin ; petiole 5-7 lin. long. Stipules 

 subulate, persistent. Inflorescences solitary; peduncle 1 in. long, 

 setulose. Receptacle oval or subtriangular, longest diameter 7 lin., 

 shortest barely 3 J lin., the margin provided with numerous linear 

 green bracts, two of which reach 4 in. in length, the remainder are 

 shorter, the shortest being 5 lin. long. Male flowers 3-4-androus, 

 with a 3-4-lobed perianth ; female scattered throughout the
