I have observed (and photographed) several times leaves, where the lateral
margins were grown together, forming pitchers, in Pinguicula vulgaris,
grandiflora and longifolia. There was always only one leave (in one case
two) with this abnormality among several normal leaves, meaning that this
dysmorphy it is not caused by genetical mutation but just by a localized
growth disorder.
