Comment of Flick album Stachys thirkei): Stachys thirkei K. Koch is a taxon belonging to the Stachys germanica agg, which is a group of very similar plants. Botanists classify them into species and subspecies in various ways. Resulting nomenclatural 'confusion' can be difficult for an amateur to navigate. We refer to Nikolić (2000) (Ref. 2) for guidance.

Stachys thirkei is most similar to Stachys germanica L. The main distinguishing features are the shape of the leaves, the orientation of the calyx teeth after flowering, and their hairiness. Stachys thirkei has mostly cuneate (wedge-shaped, gradually tapering) leaf bases, while Stachys germanica usually has truncated or eventually somewhat cordate (heart-shaped) leaf bases. The calyx teeth are widely open at the end of the blooming period in Stachys thirkei but mostly pointed straight in Stachys germanica L. Additionally, Stachys thirkei has glandular hairs on the calyx teeth (see lower right corner of picture 4), while no such hairs can be found on Stachys germanica L. However, leaf shape is variable in both species, so it's important to consider several of them to decide on their shape. Glandular hairs with Stachys thirkei are not conspicuous, so one must look carefully since they are not numerous and are hidden in thick no glandular indumentum similar to that of Stachys germanica L..

Stachys thirkei grows in Europe and West Asia, with the largest populations in Central Dalmatia in Croatia and central Greece. It is present also in Italy and Turkey (Ref.: 5).
