 leaves often smaller. Stamens 12 ; outer 9 fertile ; anthers 2-celled ; 

 anthers of first and second rows introrse, anthers of third row ex- 

 trorse or subextrorse, 2 -glandular at base. Staminodes 3, interior 

 oppositipetalous, varying in form. Germen inserted in bottom of 

 receptacle. Berry included in and slightly or closely {Caryodaphne) 

 adherent to dry or succulent receptacle. — Trees ; leaves alternate 

 penniveined, more rarely subtripliveined or three ribbed {Caryodaphne)', 

 bud-scales few; inflorescences axillary or terminal {Tropical Asia,

15. Boldu Feuill. — Flowers of Cryptocarya. Berry ovate, 

 rarely surrounded by non-adherent and dry fragile receptacle, 

 which is rarely persistent, usually falling more or less early and

 Cryptocarya. — Trees ; leaves opposite or subopposite, coriaceous 

 penniveined ; buds naked ; inflorescences axillary {Chili). See p. 432. 



16. Ravensara Sonner. — Flowers hermaphrodite (or poly-

 free equal, often inflexed at apex valvate. Stamens 12, inserted
