По своему ареалу T. litorale представляет собой балтийский вид, распространенный от Норвегии и Нидерландов до Финляндии, Эстонии и России. Из нашей страны ранее он приводился Н.Н. Цвелевым из Ленинградской области и Г. Марклундом из Псковской области. Нами пересмотрены материалы по данному виду из Ленинградской области, а некоторые местонахождения были проверены и в природе, что позволило подтвердить произрастание вида на этой территории. Сведения из Псковской области на настоящий момент остаются неподтвержденными. В Ленинградской области вид известен из трех близко расположенных точек на Кургальском полуострове, недалеко от границы с Эстонией, но нельзя исключать нахождение новых точек вида в будущем и в других местах побережья Финского залива. Секционное положение вида остается неоднозначным, различные авторы относят его к различным секциям или неформальным группам; мы также считаем секционное положение вида неясным, но выдвигаем предположение о наибольшей близости с секциями Naevosa или Hamata. В статье обсуждается возможность установления охраны данного вида. Статья иллюстрирована фотографиями типичных гербарных образцов и картой распространения.</p></abstract><trans-abstract xml:lang="en"><p>Taraxacum litorale Raunk. is a distinctive species, well-delineated within the genus by a suite of morphological, ecological, and distributional characters. A typical Baltic taxon, it inhabits maritime and sub-maritime areas in countries bordering the Baltic Sea, ranging from the Netherlands and Norway eastwards to Estonia, Finland, and Russia. In Russia, it was previously reported by Nikolai Tzvelev from the Leningrad Region and by Gunnar Marklund from Pskov Region. We revisited available herbarium material from Leningrad Region, surveyed potential localities in the field, and confirmed its presence there, while records from Pskov Region remain unconfirmed. In Leningrad Region, the species is currently known from three closely situated localities on the Kurgal’skiy Peninsula near the Estonian border. We recommend further searches for this species along other coastal areas of the Gulf of Finland. In gross morphology, T. litorale is readily distinguishable from all other Taraxacum species in Leningrad Region, enabling its reliable identification even by those not specializing in dandelion taxonomy. The sectional position of T. litorale remains uncertain, having been assigned to various groups by different authors. Here, we suggest that its overall morphology and geographical distribution align most closely with sections Naevosa or Hamata. We also consider the prospects for regional-level protection of this species. A distribution map and images of representative herbarium specimens are provided.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Биоразнообразие Ленинградской области</kwd><kwd>засоленные местообитания</kwd><kwd>Кургальский полуостров</kwd><kwd>Н.Н.
