These barks were collected on January 1908 by Dr. H. R. Whitford and W. I. 

 Hutchinson from Port Banga, Zamboanga. They are rather large quills with 

 thick, liarsh, dirty brown scales on the outer surface. Tabique gave a very 

 dark, red infusion; tangal a somewhat light red infusion; bacauan gave an 

 intense red infusion. Pototan {Bruguiera parviflora) is a fibrous bark difficult to 

 grind; it gave a red infusion. Pototan (Bruguiera gymnorrhiza) gave the same 

 colored infusion as the previous one.
