Hypecoum erectum is a species of annual herb in the poppy family native to China, Mongolia, and Russia.

[1] The primary chemical constituents of H. erectum are hypecorine, hypecorinine, hyperectine, protopine, coptyine, allocryptopine, isohyperectine, and oxohydrastine.

Linnaeus also noted the species was found in "Dauria", referring to Dauriya in China or Transbaikal in Russia.

[6] Specimens of Hypecoum erectum were misidentified by Hector Léveillé and Eugène Vaniot after their 1905 expedition to China.

Léveillé and Vaniot authored the invalid name Hypecoum millefolium in reference to the "thousand leaves" of the plant.

[7] In Russia, the plant is found in Altai, Buryatia, Chita, Irkutsk, Krasnoyarsk, Tuva, and West Siberia.
