Erycibe paniculata Roxb.: 
Roxburgh’s plate shows a plant with yellow flowers and lanceolate 
leaves and is probably the same as Trimen’s later A’pura specimen. 
Some specimens however appear, to be referable to:

Also in S. India. 
This is said to have white, sweet-scented flowers and broader, 
longer-petioled leaves. More field work is required to establish it as 
a species.
