1. Hexanthera, Endl.—Stamina fertilia 6. Stylus indi- 

 visus. 



2. Iroucana, Aubl Stamina fertilia 8. Stylus indivisus. 



Fructus crassus valde carnosus. Semina pulpa nidulantia. 



3. Pitumba, Aubl. — Stamina fertilia 10 rarius 12. Stylus 

 indivisus. Fructus parvus, coriaceo-carnosus, epulposus. 

 Folia saepissime punctata. 



4. Crateria. — Stamina fertilia 10. Stylus apice trifidus. 

 Fructus coriaceusjsubcarnosus, trigonus, epulposus. Seminum 

 axillus multifidus. Folia punctata. 



5. Piparea, ^m6/. — Stamina fertilia 12 — 15 rarius 10. 

 Stylus apice trifidus. Fructus ut in Crateria. Folia coria-

There are no species hitherto described, with less than 6

 more than 15 fertile stamina, (or 30 altogether.)
