The "Blue Lotus" of the Nile is a phalacy. What they were really
referring to were two spp of tropical Nymphaeas, N cearulea and N.
nouchali, both of which are blue. There is a sp of tropical lily called
N. lotos, which is a white night blooming sp. Many people confuse Lotus
with Water Lilies. Lotusare the ones with their leaves held well above
the water, while tropical Nymphaeas keep their leaves on the water and
the flowers above it. So if you want a blue Lotus, you'll have to copy
somebody else's incorrect picture or dream one up for yourself, because
you'll never find a picture of one in the flesh.
