Note: — Popov (1940) described this taxon as a variety of Phlomoides laciniata (former Eremostachys laciniata var. labiosiformis Popov ), but based on the size of upper lip of corolla and calyx, Knorring (1954) recognized this variety as a distinct species, i.e. Eremostachys labiosiformis (Popov) Knorring (= Phlomoides labiosiformis ). Recently, Ranjbar & Mahmoudi (2017) described P. semnanensis as a new species allied to P. labiosiformis . They mentioned that P. semnanensis differs from P. labiosiformis by a calyx 15–18 mm (versus 20–28 mm) long and corolla 26–29 mm (versus 35–40 mm) long. However, based on the photos of P. semnanensis in its natural habitat, it seems that the plants were collected at anthesis, and the smaller flower size is due to early collection date and immature plants. Therefore, P. semnanica is considered here as a synonym of P. labiosiformis .
