Remarks: This species is quite unknown to me, and there is very 

 little to be found in the literature about it. SCHAUER and SCHIMPER only 

 place this species in sharp opposition to A. nitida Jacq., and it is 

 from their notes that the above description has been compiled, in order 

 *o be complete The species seems to me very doubtful, and were it not 

 that SCHAUER spoke of tropical American plants with white flowers and 

 that ScHiMPER followed this example, one would be inclined to think of 

 an omission as a consequence of the great confusion which has always 

 prevailed with the Avicennias. SCHAUER'S description with the exception of the 

 white flowers and almost sessile stigmas agrees exactly with that of A. offi- 

 cinalis L. A nearer examination on the spot will however help to show whether 

 the American Avicennias are really only represented by A. nitida Jacq., 

 or whether there exists also a second species, viz. A. tomentosa SCHAU.
