284 NATURAL HISTORY OF PLANTS, 



Ronahea ^ comprises Psychotrias whose inflorescences are axillary ; 

 they are compound cymes, either very short or longer and 

 ramified. 



Rudgea^ comprises Psychotrias whose limh is 4-10-dentate and 

 corolla, often hairy externally, is divided into four or five straight or 

 incurved lobes, often bearing, a little below the summit, a sort of 

 full conical horn, more or less prominent, and whose very wide seed 

 is usually involute at the face. 



Palicourea,^ very similar to Rudgea in other characters, has a 

 straight or curved corolla, sometimes gibbous at the base, and ovarian 

 cells varying from two to five in number.* 



Psathura,^ shrubs of Madagascar, consists of Psychotrias with 

 4-6-merous flowers, whose ovary has 2-6 cells. When they are the 

 same in number as the sepals, they alternate with them. The 

 inflorescences, composed of cymes, are frequently axillary ; but they 

 may also have solitary flowers. 



Triainolepis ^ has 4-7-merous flowers with a 4-7-celled ovary 

 like that of Psathura ; but the compound cymes are invariably 

 terminal. 



Strempelia'^ comprises Psychotrias of both worlds whose ciliate 

 stipules have a truncate summit as in Rudgea. and whose floral cymes 

 are umbelliform. 



Grumilea^ includes old world Psychotrias the albumen of whose 

 seeds is more or less deeply ruminate.
