This species had huge nomenclatural dispute from the era of Roxburgh! 
Basically this species is *Croton persimilis *Muell. Arg.* **Croton 
oblongifolius* Roxb. (Fl. Ind. ed. Carey, 3: 685. 1832) is an illegitimate 
later homonym ( non Delile 1814, nec Siebr. ex Spreng. 1826). A new name *C. 
roxburghii* N.P. Balakr. in Bull. Bot. Surv. India 3: 39. 1962 (nom. 
illegit.) was proposed for it which also becomes a later homonym (non *C. 
roxburghii* Wall. 1840). *C. persimilis* Muell.-Arg. described from Sri 
Lanka. The two species(*Croton oblongifolius* Roxb. And *C. roxburghii*N.P. 
Balakr.) are merged and thus 
*C. persimilis* Muell.-Arg. becomes the valid name for this widespread 
species of' great medicinal importance.
*Diagnostic  characters: *Trees or* *Shrubs, 2–20 m high, deciduous;* *leaves 
oblong, elliptic to obovate; inflorescences sub-erect to drooping; male 
flowers pedicelled, sepals 5; petals 5; spathulate to oblong, stamens 
10-15; anthers oblong, yellow;  female flowers pedicelled, sepals 5; petals 
5, spathulate;  styles usually bifid; fruits globose to subglobose.
