This is a steppe xeric St. John's wort with
pale yellow flowers very different from all the other species of the
genus from our flora. Unfortunately the species is quite rare.
Pusta Bagaului valley steep sunny slope, near
Cisteiu de Mures, Alba county, 13th of July 2006. Actually most of
the pictures below are comparisons between individuals of
Hypericum elegans Stephan (the ones with pale yellow
flowers) and Hypericum perforatum L. (the ones with deep
yellow flowers). The two species grow frequently together in the
steppe xeric and mesoxeric grasslands from Transylvania, but
Hypericum elegans is rarer.
