Hieracium diaphanoides subsp. lehbertii Zahn (1934: 494) .

Ind. loc.: “Esthland: Halbinsel Kasparwiek i. Reval (Lehbert)!”

Lectotype (designated here by Gottschlich): — ESTONIA. Lääne-Viru: Estland, Wälder bei Kasparwiek (i stl. v. Reval), July 1923 (B barcode B 10 0453951! [ Fig. 2 ]; isolectotype: B barcode B 10 0453952!).—Current names: Hieracium lehbertii (Zahn) Üksip (1960: 280) or H. diaphanoides · subsp. lehbertii Zahn.

Remarks: —The specimen bears a detailed handwritten description by Zahn under the name Hieracium murorum subsp. subsparsidentiforme . Zahn also wrote this name on Bornmüller´s label with the date “1925” when he made this description. However, he did not publish the taxon under this name, but under H. diaphanoides subsp. lehbertii with the explicit reference to Bornmüllers herbarium [“im Herb. Bornmüller (1925)”]. Although there is no reference to a collector “Lehbert” and no later correction regarding this name, it must be the type of H. diaphanoides subsp. lehbertii . In the Estonian Flora ( Üksip 1961: 122) there is a suitable figure which agrees very well with the type.
