the number of stamina. He adds as a variety the Lysimachia 
non papposa humilis Maderaspatana, Clinopodii lutei foliis non cre- 
natis, fructu caryophylloideo parvo of Plukenet, (Alm. 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 Lysimachie species fructu caryophylloideo of the elder ` 
Burman, having five petals, that has often been confounded. 
. with the Carambu. In this case the name Jussiæa caryophyllea 
should be confined to this variety, as it belongs to this genus ; 
while the Carambu or Jussiæa caryophyllea æ is a Ludwigia, which 
I would call 
Ludwigia diffusa caule diffuso, foliis lanceolatis, capsulis sub- 
pedunculatis folio dimidio brevioribus. 
Habitat in Indiæ ultra et citra Gangem aquosis.

ber, basi rudimentis foliorum prodeuntium appendiculatus, 
stipulis nudus. Flores subsessiles, axillares, solitarii, folio
