For the "blue" *passiflora, the french write the epitet

Both schools cite L. [1753, Sp. Pl. : 959],**I have no way to*check
Sp. Pl.* a comment will be appreciated.

You can find a fascimile of Species Plantarum on Gallica, at

IPNI, at

http://www.ipni.org

has Passiflora caerulea L., and, citing Index Kewensis, Passiflora
coerulea Auct. (that is various authors) as the same plant.
