From Zdenek Zvolanek
"One of the best hybridizers of the noblest Saxifrages Karel Lang, Czech from the Czech Karst died in pain today. It is a black April day with illuminations of Saxifraga burseriana whites. Karel was a keen photographer so I am posting his bright portrait of one saxatile species from Suova Gora in Northern Macedonia"

What very sad news - Karel Lang is a Saxifraga hero- We send condolences to his Family and Friends.
