Rhinanthus angustifolius

Rhinanthus angustifolius, the narrow-leaved rattle or greater yellow-rattle, is a plant species of the genus Rhinanthus. It is an annual wildflower native to temperate grasslands in much of Europe, and north and central Western Asia. The yellow flowers are mostly visited by bumblebees.

Distribution
Rhinanthus angustifolius has native distribution in:
 * Europe
 * Northern Europe: Denmark; Finland; Norway; Sweden; Estonia; Latvia; Lithuania; United Kingdom, and the northwestern Russian Federation's European Northwestern Federal District oblasts and republics, including Karelia and Saint Petersburg-Leningrad Oblast.
 * Middle Europe: Austria; Belgium; Czech Republic; Germany; Hungary; Netherlands; Poland; Slovakia; Switzerland.
 * Southwestern Europe: France
 * East Europe: Belarus; Moldova; Ukraine; and the western Russian Federation's European Central Federal District and Volga Federal District oblasts and republics; including Kirov, Moscow-Moscow Oblast, Smolensk, and Tula
 * Southeastern Europe: Bulgaria; Romania; Slovenia, North Macedonia, Croatia, and the other Balkans countries.

This annual root-parasite was formerly a widespread weed of arable land in east Britain. However, most of the remaining sites are on the North Downs, in grassland and open scrub on chalk. In Lincolnshire, it occurs on peat in an area of cleared Pteridium and on railway ballast. In Angus, a tiny colony survives in sandy coastal grassland.


 * Asia
 * Western Asia: Turkey
 * Caucasus:
 * Transcaucasus: in Armenia; Azerbaijan, and Georgia.
 * Ciscaucasia: in the Russian Federation's Eurasian North Caucasian Federal District oblasts and republics; including Chechnya, the Sochi region in Krasnodar Krai, and North Ossetia.
 * Pontic–Caspian steppe: western Kazakhstan; the Russian Federation's central-western Asian Southern Federal District oblasts and republics; including Kalmykia Republic and Volgograd.
 * West Siberian Plain: the Russian Federation's northwestern Asia region of the western Siberian Federal District; including the Oblasts of Chelyabinsk, Novosibirsk, and Omsk.
