* The genus Alpinia of Linnaeus was based wholly on a tropical Amer- 

 ican plant, Alpinia racemosa Linn. = Renealmia racemosa A. Rich., and is 

 thus identical with Renealmia Linn. f. (1781), which it should replace. As 

 between 'the two generic names, no matter which one be applied to the 

 American group, Alpinia is clearly not applicable to the Indo-Malayan 

 genus long known under this name.
