First report of Euphorbia davidii in Bulgaria
Euphorbia davidii (Euphorbiaceae) was found for the first time in 2009 in Bulgaria. The species was recorded near the city of Varna (Black Sea Coast) in the shunting yard of the Razdelna railway station and in the ferry harbour complex at Lake Beloslav. About 100 fruiting plants were observed in the first locality and a few thousands in the second where the species was very abundant.
