Phlomoides baldschuanica (Regel) Adylov, Kamelin & Makhmedov , in Opred. Rast. Sred. Azii 9: 95. 1987.

≡ Eremostachys baldschuanica Regel , in Trudy Imp. S.-Peterburgsk. Bot. Sada. 9, 2: 541. 1886. = Eremostachys baldschuanica var. trautvetteriana (Regel) Popov, Novye Mem. Moskovsk. Obshch. Isp. Prir. 19: 107. 1940.

Type: — Tajikistan, Amudarya in the eastern Buchara region Tschorabdarra, the river Kysylsu baldschuan, 1828 m, June 1884, A . Regel s.n. (holotype: LE!) .

Perennial herbs, 60–90 cm tall. Stems erect, glabrous or with sparse simple and stellate trichomes, more densely pubescent on nodes. Basal leaves oblong elliptical, 15–30 × 10–12 cm long, wedge-shaped or round at the base, large and shallowly or pinnately lobed, margin crenate, adaxially sparsely stellate pilose, abaxially sparsely stellate pilose, denser on veins, petioles 6–13 cm long; stem leaves similar, smaller, petioles short. Verticillasters multi-flowered; floral leaves ovoid, margin crenate, sessile, longer than verticillasters at inflorescence base, becoming shorter than them above; bracts lanceolate, rigid, half as long as the calyx, with branched and glandular trichomes. Calyx tubular, 16–18 mm long, with prominent veins, pubescent in the lower half with branched and glandular trichomes; teeth triangular, 1–1.5 mm long. Corolla yellow, posterior lip pubescent on the outside, bearded inside, margin denticulate; lower lip 3-lobed, middle lobe shortly notched, lateral lobes broadly rounded; posterior filaments with long, linear, fringed appendages at base. Mericarps with long hairs at apex.

Phenology: —Flowering from May to August, fruiting from July to November.

Distribution, habitat and ecology: — Tajikistan and Uzbekistan; new record for Uzbekistan, occurring in south western Gissar. It grows on stony or gravelly slopes from the middle altitude to the alpine zone of mountains, 2000– 3400 m (Adylov & Makmedov 1987) ( Fig. 3 ).

Etymology: —The specific epithet refers to Baldschuan in Tajikistan, where the species was found.

Common name (assigned here): — Baldschuan flomoidesi ( Uzbekistan name).

Taxonomic notes: — Phlomoides baldschuanica is morphologically similar to P. fulgens ( Bunge 1873: 80) Adylov, Kamelin & Makhmedov (1987: 94) , but can be distinguished by its abaxially leaves green, with sparse stellate trichomes (vs. abaxially leaves gray, with dense stellate trichomes), and bracts wider and stiffer lanceolate or linearoblong (vs. bracts linear and linear subulate).

Conservation status in Uzbekistan: — Phlomoides baldschuanica is distributed in only one locality of Uzbekistan, the Gissar ridge, the basin of Kashkadarya (Gissar state reserve). Data on the population of the species is insufficient, as research was conducted many years ago. Thus P. baldsshuanica should be classified as Data Deficient (DD) based on the IUCN Red List Categories and Criteria ( IUCN 2019). Nonetheless, considering the restricted distribution range, it is possible to hypothesize that after collecting data on the threats and on the population, this species will be attributed either to the category Critically Endangered (CR), based on the IUCN criteria B and C (e.g. Wagensommer et al. 2017, Wagensommer & Venanzoni 2021), or to the category Near threatened (NT), especially when no decline is observed (e.g. Perrino et al. 2018).
