Pinguicula 'Sethos'

Pinguicula 'Weser'

 

"Of these (hybrids) I would mention [Pinguicula ' Sethos ' {Hort.Slack}] ([[Pinguicula moranensis {H.B.K.}] * [Pinguicula ehlersiae {Speta & Fuchs}]]), a fine, very floriferous clone with large orchid-purple flowers with a many-rayed mouth like a white star; [Pinguicula ' Weser ' {Hort.Slack}], of the same parentage and with rather similar flowers, has a solitary white streak down the central lower lobe and dark veins."
