Back from spain (I live in France) for a 4000 km trip to see : P. longifolia subsp. longifolia in pyreneans mountains in south west of France, in Anisclo canyon, then near Madrid to see Pinguicula dertosensis in Hoz de Beteta, and finally, south near Jaen to see P. vallisneriifolia in Sierra de Segura, Sierra de Cazorla and Sierra de las Villas (3 populations only due to few time but Steiger noted 74 differents populations in the flower size, the coloration...), then P. mundii.
Back to France, we pass near the gorges of Tarn (near the town of Millau) to see P. longifolia subsp. caussensis and back home yesterday. A 4000 km in 6 days but with many pictures to share soon with you via A world of Pinguicula (when my pictures will come back from the photografer.
If one day you go there, the flowering periods are the following :
Middle of April :
