D. guttatus and D. broteri – are cited as accepted. However, the morphological differences of these taxa are interpreted inconsistently in different sources, and their features largely overlap ( Heywood 1968b; Sáenz Laín 1981; Asenov 1982; Al-Safadi 2008; Martínez-Flores & al. 2016; Arbizu & al. 2016). Recent molecular and morphological studies and comparison of type specimens proved that these names are synonyms ( Arbizu & al. 2014, 2016; Martínez-Flores & al. 2016). Daucus guttatus is widespread in the E Mediterranean and SW Asia from S France and Italy to W Iran, predominantly in coastal areas ( Hand 2011 +; Martínez-Flores & al. 2016; POWO 2023d). The locality closest to the W Crimea is the Black Sea coast of Bulgaria and Romania, where the taxon is interpreted as the Balkan endemic D. guttatus subsp. zahariadii Heywood ( Heywood 1968a, 1968b; Beldie & Váczy 1976; Asenov 1982; Hand 2011 +; POWO 2023d). Morphological characteristics of Crimean plants in general correspond to the description of this taxon, viz.: plants annual; stems 20–60 cm tall; umbels 4–7 cm in diam., with 8–22 rays; bracts shorter than or as long as rays, usually 3-fid; flowers of central umbellule dark purple, other umbellules with no darkpigmented flowers; mericarps 3–4 × 1–1.5 mm, with 9–13 spines in each secondary rib, central spine 1–2.5 × as long as mericarp width. Some authors consider the allocation of subspecies in D. guttatus inappropriate, because the species is very polymorphic throughout its range ( Martínez-Flores & al. 2016). For E Europe, D. guttatus is reported here for the first time. Recently, this species was found in the N Caucasus in Dagestan, where it is considered an alien ( Shner & al. 2017; https://www.gbif.org /occurrence/3747373470). For Crimea, D. guttatus is a native plant. It grows in steppe and semi-natural grasslands, sometimes as weed near roads, on the outskirts of vineyards and on household refuse in suburban areas. It occurs scattered mainly in the W part of the peninsula.
