 receptacle saccifonii or lageniform, more or less concave, perianth- 

 leaves 00 (5-15), ~- or pluri-seriate, imbricate; innermost petaloicl. 

 Stamens en free inserted on throat of receptacle, sterile linear in 

 female flowers, fertile in male and hermaphrodite flowers, filaments

 extrorse, dehiscing by 2 uplifted valves ; connective truncate at apex. 

 Carpels oo, in male flowers sterile, ovary free, 1 -celled, at apex pro- 

 longed into a linear style ; ovule 1 , sub-basilar anatropous, micropyle 

 inferior extrorse. Achenes oo, surmounted by persistent plumose 

 styles, included in indurated broadened lageniform receptacle, marked 

 by the scattered scars of fallen bracts either below the apex or from 

 base to apex ; perigonium finally dilated at apex or unequally 2-4- 

 cleft from apex to base, pericarp thin more or less adherent to seed. 

 Albumen copious oily ; embryo minute straight ; radicle inferior. — 

 Aromatic trees; leaves opposite; flowers axillary solitary or cymose; 

 bracts 2 opposite inserted below receptacle, first embracing flower,
