Where have you found a reference that M. Pissard discovered this rose and sent cuttings to M. Godefroy? I have only found that M. Godefroy grew this rose from seed received from M. Pissard. If Godefroy grew it from seed then it cannot be the original garden rose discovered by Pissard. The name Nastarana or Pissardii belongs to another rose.
This is based on Ivan Louette's research. You could consider that Pissard "discovered" the seed, which is the rose commercialized as 'Nastarana'. The seed parent of these seeds is unknown.
In the 1886 Revue horticole article, Carrière states plainly that Rosa Godefroyae is very different from R. Pissardi on multiple counts. This confuses the issue of when the actual species rose from Tehran really reached France (Europe?), since Godefroy-Lebeuf's seedling was apparently not R. Pissardi, though it was treated as if it were.
Another puzzle is how Godefroy-Lebeuf so readily managed to raise a seedling from a rose with seeds that were notoriously sterile (see the 1880 Revue horticole article by Carrière).
I notice that on the description page, Pissard is credited with the discovery of R. Pissardi; that is debatable since it had been an important (and imported) garden rose in Tehran long before Pissard discovered it, but it does seem wrong that the description page implies that the rose was discovered in France, 1879. Pissard certainly discovered the rose in Persia.
