     The hybrid Mexican butterwort Pinguicula x weser is a cross of P.
moranensis and ehlersae. I too have grown this plant and pollinated the
flowers to get seed. The seed of this hybrid did prove to be viable and
germinated well. This seems odd to me since the chromosome numbers of the
parents are reported to be different. P. moranensis 2n = 44, P. ehlersae
2n = 32. Perhaps these counts are incorrect?

I have pollinated flowers of two other intraspecies hybrids of Mexican
butterworts and these produced no seed. These were P. agnata X gypsicola
and P. macrophylla? X agnata?. The later I do not know the parentage; it
was made by Leo Song and goes by the name Titan by him or Starfish Plant
sold by Booman Floral.
