Serbia: Okrug Pčinja
Vranjanski Slez (Serbian)
extinction date: (?)
|The Vranja Marshmallow was
growing exclusively around the city of Vranja in Serbia's southeast.
The species disappeared (date ?) after parts of its habitat were destroyed due to urban development by the city of Vranja, resp. the remaining parts were reclaimed for agriculture purposes.
I have to admit that the exact status of this plant (accepted species or synonym) seems not to have been clarified yet.
In the case of another Serbian form of Marshmallow, the Kragujevac Marshmallow (Althaea kragujevacensis), which was growing near the city of Kragujevac in Šumadija / Central Serbia it was long thought to represent a distinct and now extinct, endemic Serbian species.
It is now however treated as a synonym of the Common Marshmallow (Althaea officinalis).
