Good after a little research and comment with several collectors and see the photos we all come to the conclusion that it is a hybrid, not a species,.
One of the most relevant patterns that betray this penguin sold as (Gigantea), is its pronuncioado funnel rather long with respect to true flower of P.Gigantea, as well as its pattern of color of the flower
We have all opllined individually that such a plant is truly P xTina,
After contacting the seller privately to ask for an explanation and dialogue. He continues to insist that he does not sell Tina ,,,, only Gigantea
Here I show the differences between both species
Mr. Michal Parvanov (MISO) nickname in this forum I think you should reconsider and truly find out if your provider is really cheating you by supplying a pinguicula that is not, because you sell us a plant that does not correspond to your description, and that will be call bad praxis
And your responsibility as a seller is to know what you are selling. and as an amateur to know what he has as a plant.
With this I only hope to open a debate and inform you that if you are a producer you should know what you sell.
