•' Perfect seeds large, broadly winged." (B.Fl. III, 254). 



Fertile seeds rather large, black-brown and shining, their appendage pale or dark brown . . . 

 provided with a large terminal membranous appendage. Sterile seeds much smaller and narrow." (Figs.

With a flattened ovoid seed terminated by a long (slightly exceeding the length of the seed itself) 

 membranous wing. Colour brown. Sterile seeds linear, numerous. Woolngi (Northern Territory,
