This plant is known to the Malay population of Perak as the source 

 of Minyah Plang, a dark brown viscid oil which is in great repute for the 

 cure of certain skin diseases. An interesting note upon the plant and 

 its oil by Mr. E. M. Holmes of the Pharmaceutical Society of London 

 is to be found in the Journal and Transactions of that Society, VdL 

 L1I, p. 389. The stigma in this species, prior to dissection, appears to 

 be sub-globular with a central groove ; and it is only after careful 

 manipntation that it is seen to be bent on itself. Some specimens of 

 this were by mistake issued from the Calcutta Herbarium under the 

 name Microstemon officinale, Holmes.
