A new Scrophularia (Scrophulariaceae) species without staminodes in the enigmatic ?Canina clade? from the Western Taurus (Türkiye)

The new species of Scrophularia was discovered among the screes and stony slopes of the Alakır Valley (Antalya) located in the Western Taurus. The most remarkable morphological feature of the species is its flowers without staminodes. With this feature, the species is unique among the representatives of the ?Canina? clade in Türkiye. The new species is closely related to S. floribunda endemic to Türkiye and East Aegean Islands (Greece) according to our phylogenetic analyses based on the nuclear ITS and chloroplast trnL-F regions. Apart from its corollas without staminodes, the new species differs from its morphologically similar species by having densely glandular inflorescence (incl. calyxes), relatively small corollas, corolla lobes with a narrow white border, and very long filaments.
