Not without reason I wrote the *calyx* lobes (= sepals, i.e. not the
petals, which are the corolla lobes) are truncate in _P.reticulata_. The
corolla lobes are much the same in both species.

What are these differences?

Yes, plants of German "origin" (they are of course originally Mexican)
labelled _P.kondoi_ are most probably _P.reticulata_, a quite widespread
and fairly variable species which has been collected several times, and is
cultivated in many collections.
Only very few plants which originally came from the Kondo collection, Japan
or from Chapel Hill Botanic Gardens, NC are really _P.kondoi_, a species
apparently not very abundant in nature as well as in cultivation.
Moreover, intermediate forms between these two do exist, making unambiguous
ID difficult sometimes. But as far as I know, no true _P.kondoi_ (with
elliptic- obtuse calyx lobes and secreting-glandular hairs on the pedicel)
has been collected since its description.

Kind regards
