Fertile seeds dark brown, 4 mm. long, 3 mm. broad, ovate, flattish to somewhat 

 conical in outline, surrounded by a slightly thickened membrane, which is narrower 

 and thicker than the membrane surrounding the seed of E. macrocarpa. The more 

 conical seeds have also the same very narrow radial ridges extending from the hilum 

 to the outer edge, the whole seed is minutelv pitted-rugose ; the flat seeds have scarcely 

 any ridges. Hilum ventral, ovate, very small. 



Sterile seeds dark brown to reddish-brown, polymorphic, the short ones angular 

 and more or less cubiform, about 3 mm. long, the narrow ones linear, quadrangular, 

 straight or curved, awl-shaped to somewhat clavate. while some are chisel-shaped at the 

 top. In the sample examined, the sterile seeds are fully twice as numerous as the fertile 

 seeds. 



E. Ifsingiana. 



Fertile seeds pale brown, about 4 mm. long, 3 mm. broad, somewhat orbicular 

 to ovate in outline, flat or nearly so, more or less pitted-rugose, the thin membrane 

 sometimes forming a minute wing-like expansion around the edge of the seed, the back 

 slightly convexed. with a few shallow depressions. ' Hilum ventral, circular, verv small, 

 light or dark coloured. 



Sterile seeds very numerous, and variable in shape, all minutely pitted-rugose, 

 angular and cubiform to linear, awl-shape or clavate. 



E. angulosa. 



Fertile seeds dark brown, rather dull, 4 mm. long, 3 mm. broad, more or iess 

 compressed ovate to orbicular, with or without a very narrow membrane surrounding the' 

 seed, the inner face pitted and also more or less alveolate in appearance, owing to the 

 short, irregular, radiating ridges surrounding the hilum ; some seeds are, however, almost 

 plain, the back convexed, minutely striate. Hilum ventral, small, orbicular, paler 

 than the seed, the attachment scar sometimes rather broad and edged with a thin, 

 sharp, irregular ridge. 



Sterile seeds reddish-brown, polymorphic, 1-3 mm. long, about 1 mm. broad, 

 the longest usually awl-shaped. The percentage of sterile seeds appears to be fully 

 80 per cent. 



Series Heteropfera (Eudesmiese in part.) 

 Fertile seeds usually dark-brown, 4-6 mm. long, broadly ovate to oblong, 

 surrounded by a fairly well developed membranous-like wing, and with 2-4 smaller, 

 more or less transverse hyaline wings. Hilum ventral. 



Sterile seeds reddish brown, subulate to cubiform, 1-4 mm. long. 



E. endesmioides. 

 E. tetragona. 

 E. tetraptera.
