ments more or less, usually wholly, united ; anthers 2-cellccl, turned 

 outwards. Ovary superior, i-cclled ; ovule i, ascending, inverted ; 

 stigma I. Fruit fleshy, usually dehiscent. Seed with an aril ; albumen 

 copious ; embryo small. — Genera 9, species 25. Tropics. (Plate 49.) 



1. Stamens 30 — -40 ; filaments united at the base. Style distinctly developed. 



Aril very small. Inflorescence head-like. — Species i. Madagascar. 



Mauloutchia Warb. 



Stamens 2 — 24 ; filaments wholly united. Style very short or absent. 



Aril distinctly developed 2 



2. Flowers with a bracteole at the base of the perianth, rather large, in racemes 



or panicles, or the female solitary. Anthers 8 — 24. Fruit ovoid, 

 dehiscent. Aril slit. Albumen ruminate. Embryo with spreading 

 cotyledons. — Species 2. Cultivated in several tropical islands. The 

 seeds (nutmeg) and the arils (mace) are used as spices and medicaments 

 and for the preparation of perfumes ; the pericarp is edible.
