158 MESSRS. BAKER, MOORE, RENDLE, RIDLEY AND WERNHAM 



obovoid-pvriform, 6 cm. long, 2.2 em. wide, below, 4 cm. above. Spa- 

 dicels on .75 mm. long stalks, the bcdy twice as long. Ovary .4 mm. 

 long ; style barely 1 mm. 



The material consists of two specimens, two male and two 

 female, only the latter with the rhizoma attached. Nevertheless they 

 are considered to form but one species, and that although the 

 receptacular bracts are broader in one case and a little differently 

 i narked on their truncate top; this, however, may perhaps be a 

 matter of age. 



Besides the deeply furrowed pustules of the rhizome the chief 

 marks of the species are the quadrangular tuberculate tops of the 

 bracts, the bottle-shaped spadicels and the subsessile ovaries.

Agrees with the description in Bull. Mus. Nat. Paris, 1914, p. 

 399, except that the most advanced fruit, evidently not yet ripe, 

 measures only 5 mm. in length instead of 8-9 mm. Some doubt must 

 therefore attend this determination, especially as M. Lecomte, with 

 one exception, does not give floral measurements.
