The Pyrenees are famous for their flora, many of which are endemic. Here is a small selection of what we saw.
Pyrenean Saxifrage
Saxifraga longifolia and Yellow Saxifrage
Saxifraga aretioides.
Vitalonia
Vitalonia primuliflora and Entire-leaved Primrose
Primula integrifolia. I found these two species of alpine primrose growing at 2200m on Punta Acuta.
Two species of Pyrenean lily, Dipcadi
Dipcadi serotinum (photographed at Sierra de la Pena NOT Ordesa), and Pyrenean Hyacinth
Hyacinthus amethystinus.
Another species of lily, Tofield's Asphodel
Tofieldia calyculata, a very close relation of the Scottish Aspohodel
T. pusilla which I found growing in Teesdale last year. Echinospartum
Echinospartum horridum, is a close relation of Gorse
Ulex europaeus.
Pyrenean Rockrose
Helianthemum nummularium pyrenaicum. This beautiful plant is a sub species of the yellow Common Rockrose which grows in the UK.
Globeflower
Trollius europaeus growing in profusion in the Valle de Otal, and Erect Clementis
Clemantis recta. Valle de Otal was an excellent site, and well worth a visit with lush, wet alpine meadows, and lots of species which I didn't find in the Ordesa Valley
Two Pyrenean specialities, the insectivorous Long-leaved Butterwort
Pinguicula longifolia and Ramonda
Ramonda myconi.
Pyrenean Columbine
Aquilegia pyrenaica and Pyrenean Rock-Jasmine
Androsace pyrenaica.

Asphodel
Asphodelus albus in the Valle de Otal and Rock Snapdragon
Antirrhinum sempervirens on Punta Acuta.
