Keywords: Corydalis, section Strictae, Western Pamirs.
Summary. A new species, Corydalis yazgulemica Mikhailova et Sochivko (sect. Strictae (Fedde) Wendelbo), is described from Tajikistan, Western Pamirs, Yazgulem range. The species differs from C. rarissima Mikhailova by linear (not elliptic) capsules and shorter pedicels, from C. bucharica Popov - by smaller plant size, reticulate seeds and rocky habitat.

Аннотация. Описан новый для науки вид Corydalis yazgulemica Mikhailova et Sochivko из секции Strictae (Fedde) Wendelbo. Материал собран в Таджикистане, на Язгулемском хребте Западного Памира. От C. rarissima Mikhailova новый вид отличается линейными (а не эллиптическими) коробочками и более короткими цветоножками, от C. bucharica Popov - меньшим размером растения, ячеистой поверхностью семян, скальным местообитанием.
For more than 17 years we have been studying trophic links between Corydalis DC. and butterflies of the genus Parnassius Latreille (Papilionidae) in Middle Asia. Considerable herbarium material was collected from hard-to-reach localities on non-tuberous species of Corydalis - host plants of butterflies caterpillars. The territory of Tajikistan, especially Gornyi Badakhshan, was in our main focus which allowed to clarify the composition and distribution of the genus Corydalis in the Pamirs
(Mikhailova, Sochivko, 2011; Sochivko, Mikhailova, 2014, 2015).
The xerophilic section Strictae (Fedde) Wendelbo is the most species-rich among non-tuberous Corydalis. 12 species are known from Tajikistan, 7 of them being endemic (Mikhailova, 2021). New plant from section Strictae was found in Yazgulem range, Western Pamirs, in the summer of 2021. It differs from all known species in the totality of characters and is described here as a new taxon for science.

Distribution in Tajikistan: Western Pamirs. Endemic.
Affinities. The new species differs from the related C. rarissima Mikhailova by shorter (6-12(17) vs. 15-35 mm long) pedicels, linear (vs. elliptical) capsules 15 x 2-2.5 (vs. 7-8 x 3) mm, and shorter (5-6 vs. 8-9 mm long) style. From C. bucharica Popov, the new species differs by smaller (6-15 vs. 30-50 cm) plant size, reticulate (vs. smooth) seeds and rocky habitat (Table).
Note. No traces of damage to plants by caterpillars of Parnassius butterflies were found.
