the number of stamina. He adds as a variety the Lysimachia 

 non papposa humilis Maderaspatana, CUnopodii luteifoliis non cre- 

 natis, fructu caryophylloideo parvo of Plukenet, {Aim. 236. Phyt. 

 t. 203. f. 5.), which is no doubt remarkably like the Carambu ; 

 but I think Plukenet was too correct to describe one plant by two 

 names on the same sheet of paper ; and I therefore suppose this 

 to be the LysimachicE species fructu caryophylloideo of the elder 

 Burman, having five petals, that has often been confounded 

 with the Carambu. In this case the name Jussiaa caryophyllaa 

 should be confined to this variety, as it belongs to this genus ; 

 while the Carambu or Jussiaa caryophyllcea a, is a Ludwigia, which 

 I would call 



Ludwigia diffusa caule diffuso, foliis lanceolatis, capsulis sub- 



pedunculatis folio dimidio brevioribus. 

 Habitat in Indiae ultra et citra Gangem aquosis.
