To judge this habitat for its fitness for P. alpina you should visit it for
a few consecutive years at different moments. Then you will know more
about the continuity of the dryness of the place and the stability of its
P. alpina population.

Your description of the petals reminds me of P. leptoceras from the
Maritime Alps. Take a look at pictures 70126 and 70154 in the database.
Casper did not mention P. leptoceras in La Vanoise but indicates places
close to it. The form of the seed cap from your drawing resembles on the
other hand those of P. grandiflora (the cap of P. leptoceras is globulose)
! Nevertheless, I think your determination was correct. Casper didn?t
report hybrids between P. leptoceras and P. grandiflora.
Gilles, roughly estimated, how many malformed flowers did you see ? I am
curious to know if the plants from your seeds will produce similar flowers.
