Anavinga. Rheed. Mai. 4, t. 49. 



A pretty large tree, with an erect trunk, and numerous 

 spreading and drooping branches, and branchlets.- Found 

 in the garden of Mr. Cowper on the banks of the Hoogly 

 just below Calcutta, and was in full blossom in March, 

 the old leaves were then falling, and the new ones just be- 

 ginning to appear. 



Leaves alternate, bifarious, drooping, ovate-oblong, and 

 oblong serrulate, downy underneath. Petioles short, 

 round, villous. Stipules small, villous, caducous. Flowers 

 axillary, or from the old axills of the new leafless branch- 

 lets, much crowded into globular heads, small, of a pale 

 green. Peduncles short, one-flowered, surrounded at their 

 insertions with numerous, short, chaflFy, villous involucres; 

 these, when the flowers are removed, form a round chaflfy 

 receptacle, like that of many of the syngenesious flowers. 

 Calyx five-leaved ; leaflets ovate, villous. Corol none. 

 Nectaries eight subclavate, ciliate bodies, distinct from 

 and alternate with the antheriferous filaments, and about 

 half their length. Filaments eight, subulate, rather 

 shorter than the calyx. Anthers two-lobed, on the an- 

 thers or the filaments being touched, or otherways irrita- 

 ted, they immediately expand and approach the base of 

 the stigma, by means of an articulation at the base of 

 the filament, which admits of this motion. Germ above
