Series Pyramidales-D-shaped. 



Fertile seeds light brown to jet black, 1 to 7 mm. long, \ to 4 mm. broad, somewhat 

 pyramidal, cubiform, oblong or elongated-pyramidal to D-sliapcd, thick or compressed, 

 with 1-5 more or less prominent diverging ridges, the surface microscopically pitted 

 rugose. Hilum terminal, usually conspicuous. 



Sterile seeds hard and brittle, somewhat cubiform, pyramidal to D-shaped, 

 the latter sometimes much compressed. In a number of cases, when the colour of both 

 kinds of seeds is the same, it is sometimes difficult to distinguish one class of seed from 

 the other, but as a general rule the sterile seeds are smaller and harder, and often more 

 glossy than the fertile ones.
