Campanula troegerae

Damboldt

Infrageneric Taxa

Campanula troegerae Damboldt, sp. nov. [sect. Symphyandriformes (Fomin) Charadze]. Fig.2.1)

Known to me only from the type gathering, this beautiful new Campanula is closely allied to Campanula betulifolia C.Koch (incl. Campanula finitima Fomin) from NE Anatolia. I am glad to have the opportunity to name this species after Annemarie Troger (Berlin), who has made so many fine drawings for our work in the Campanulaceae.2)

Planta perennis, saxatilis, basi indurata ob bases petiolorum persistentes squamosa. Caules ascendentes-erecti, flexuosi, simplices, foliosi, 12-17cm longi.3)

Graham Nicholls - Note: Campanula seraglio, this species is fairly new to cultivation and is in the same group as Campanula betulifolia, Campanula troegerae, Campanula choruhensis etc.
