brown with a succulent pericarp; in the dried, the pericarp is very thin and membranous, 

 peeling from the yellowish-brown seed. Seed 1'75 to 2'25 mm. long. Testa more or less 

 distinctly marked with 25 to 30 more or less regular rows of small areolae, which are 

 subquadrate about the midle of the seed, but become irregularly 5- to 6- angular towards 

 the ends and the prominent raphe.
