Haberlea rhodopensis - a relic plant with a distribution area in the Balkans.

Haberlea species are perennial herbaceous plants . The alternate leaves stand together in a basal rosette. The leaves are divided into short petioles and leaf blades. The simple leaf blade is spatulate with serrated to serrated leaf margin and rough hairs.

Two to ten flowers sit together in long-stemmed, zymous inflorescences . The bracts are small and narrow. The hermaphrodite flowers are five-fold and zygomorphic with double perianth . The five unevenly large, lanceolate sepals are fused. The five petals are fused bell-shaped; they are usually blue, rarely white, with yellow dots in the corolla tube. The two pairs of stamens arise from the petals, which they do not protrude.

They bloom from May to June.

The flower formula is: ${\displaystyle \downarrow K_{5}\;C_{(5)}\;A_{2+2}\;G_{\underline {(2)}}}$

Double, dry capsule fruits are formed. The fine seeds do not last long, so they should be sown immediately.

Systematics

The generic name Haberlea is dedicated to the German botanist and meteorologist Karl Konstantin Haberle (1764 to 1832), whose pupil Imre Frivaldszky first described Haberlea rhodopensis in the annals of the Bulgarian Scientific Society in 1835 . The first specimens of this species were found in 1834 during an expedition in the Balkan Mountains of Bulgaria.

In the genus Haberlea there are only two species that are native to the Balkans:

• Haberlea rhodopensis Friv. : It occurs in Bulgaria and Greece ;
• Haberlea ferdinandi-coburgii Urum. : It occurs in Bulgaria and was described in 1902 on the basis of specimens that had sparsely hairy leaves - a feature that specimens of Haberlea rhodopensis , however, also havein varying degrees and that has no taxonomic relevance.
