Vogt, Robert & Gottschlich, Günter, 2023, Type material in the Hieracium (Compositae: Cichorieae) collection of Joseph Bornmüller, Phytotaxa 613 (2), pp. 81-126 : 109

Hieracium pannosum var. brachylasion Bornm. & Zahn in Zahn (1921: 565).

Ind. loc.: “ Amasia: Sana-Dagh , 1400–1600 m, und Berg Logman, 600–800 m (Bornmüller, Pl. Anat. No. 1450, 1446 pp.)! Tossia: Snütschtüdere und Schakirla (Sintenis l.c. n. 4554 pp., 4667 pp.)!”

Lectotype (designated here by Gottschlich ): — TURKEY: Amasia, in rupestribus regionis montanae, “Logman”, 600–800 m, 3 July 1889, J. Bornmüller (Pl. Anatoliae oriente, no. 1446) ( B barcode B 10 1154366!).—Current name: Hieracium pannosum subsp. bornmuelleri (Freyn) Murr & Zahn in Murr et al. (1907: 115).

Remarks: —The specimen in B (barcode B 10 1154366!) of Hieracium pannosum subsp. bornmuelleri comprises three plants. Zahn noted on his label: “Dabei ein Ast der wohl zur Form brachylasion geh i rt” [Contains a plant that probably belongs to var. brachylasion ]. In the protologue he characterized this variety with “ramis pedicelisque subepilosis”. This applies only to the middle of the three plants, which is selected here as the lectotype.

On the basis of “Plantae exsiccatae Anatoliae orientalis N° 1446” Freyn described his Hieracium bornmuelleri var. ramosissma . However, the material of number 1446 appears to be heterogeneous as the plants present are not branched, not to mention that a stronger branching has no taxonomic value.
