Notes:— The taxon was firstly defined with the name Bolanthus stenopetalus by Hartvig and Strid in 1987 ( Hartvig & Strid, 1987). The type adress of taxon is Muğla Sandras mountain and also known that there is a taxon Bolanthus frankenioides in this area ( Huber-Morath 1967). The type specimen of taxon and samples collected in field studies on Muğla Sandras mountain have been examined in detail. The article is published by Hartvig and Strid and detailed descriptions have been gathered. The articles and detailed descriptions published by Hartvig and Strid were combined and it was determined that they were ciliated and long-leaved, having short pedicellate flowers, petals pink and oblanceolate, ovary with 8–10 ovules which were given as a difference by the researchers, and that their characters were already features of the Bolanthus frankenioides var. fasciculatus taxon. Fort this reason, it was decided to select the species B. stenopetalus as synonym to the B. frankenioides var. fasciculatus . Its distribution in Türkiye was given in Figure 19 .
