 genus consists of beautiful trees, natives of the East Indies : 

 their leaves are large, and of a leathery substance ; their 

 flowers axillary or terminating, sometimes very large ; the 

 fruit approaching to that of Clusia. The species are,

 According to Vahl, the peduncles are frequently from four 

 to eight flowered, branching at the base. Native of Ceylon, 

 where the natives call it dinpura.

 inches long, and tour to six broad ; flowers small, Jellow, on 

 simple stalks, growing many together in bundles along the 

 branches ; pericarp pendulous, size of a small nutmeg ; seeds 

 reniform. It flowers in March and April, and is a native of 

 the mountainous parts of Commando!.

 rounded at the base, deeply three or four-cleft, obtuse. Co- 

 roLla: petals very wide, ventricose, convolute at the sides. 

 crenulate, inserted into the calix below the stamina, placed 

 at the lower side. Stamina : filament a diadelphous, (single

1. Diodia Virginica. Stem branching, procumbent, smooth 

 and even, red ; branches alternate ; leaves opposite ; flowers 

 white. The calix in some is two-leaved only, in others un- 

 equally four-leaved, that is, with two very minute leaves 

 placed in the interstices of the larger, and this even seems to 

 be the more natural number. Native of Virginia.
