Morphologically, the leaves of Bacopa monnieri are fleshy and
succulent (yields more extract) than Bacopa floribunda leaf.
The taste of the leaf and stem powders was strong, with bitter
ends in mucilage, while Bacopa floribunda was only bitter
in taste. The Bacopa monnieri leaf and stem showed more
lignified fibers, oil globules, tannin material and prismatic
crystals of calcium oxalate than Bacopa floribunda. Study
revealed presence of higher bacoside A content in Bacopa
floribunda, i.e. 26% in leaf and 27% in stem, compared with
Bacopa monnieri, i.e. leaf 22% and stem 18%. Considering the
hemolytic action of bacoside A, it seems that Bacopa monnieri
is more popular in regular use, than Bacopa floribunda
