Une of the commonest plants in India, if, as most suppose, the shrubhy O. penta- 

 ' phylla and arboreous 0. arborea are the same species. This is a point to which observers 

 in India should pay attention. Thwaites, who distinguished arborea at one time by 

 (he short glandular ovary narrower than the spheroid disk, short depressed style as 

 broad as the distinct discoid stigma, and the smaller panicles, finds these characters not 

 to hold as he expected. The leaves, which are evei-green, vary from 1-5-foliolate, and 

 the leaflets from ]-9 inches long, and are broad or narrow, obtuse acute or acuminate, 

 oblong elliptic or obovate or lanceolate, quite entire or crenulate, rather membranous, 

 pale and reticulately veined. Flowers small, white, in pubescent panicles that are very 

 variable in size and composition. Berry white, globose, usually the size of a large pea, 

 in var. 3, as large as -i cherry. — I follow Prof. Oliver's classification of the first two 

 varieties; to which be gave many weeks of study with copious materials at his command. 

 The 3rd is added from Wight's Illustrations and Herbarium. Upwards of 200 speci- 

 mens are preserved in the Herbarium at Kew from different collectors and habitats.
