Male flowers: Perianth small, 6-8-lobed. Stamens numerous; 

 anthers subsessile, 2-celled, dehiscence longitudinal. Female flowers : 

 Perianth 5-lobed. Ovary 1 -celled ; stigma sessile, hemispheric, slightly 

 excentric, becoming lateral in fruit ; ovule solitary, pendulous. Fruit 

 fleshy. Seed closely applied to the pericarp ; raphe branched ; embryo 

 small ; endosperm ojly. — Leaves alternate. Flowers racemose. 



Monotypic, endemic. 



In a note with one of the specimens at Kew, Pierre says that the ovules are soli- 

 tary, and not in pairs, as stated in his original description. This genus is closely 

 allied to Xymalos, from which it differs chiefly in the curious structure of its seeds.
