[Named for Dr. Johann Friedrich Gustav von Eschscholtz (1793-1831), a Latvian or Estonian surgeon, entomologist and botanist who came with the Russian expeditions to the Pacific coast in 1816 and 1824 with his friend and companion Adelbert von Chamisso who put Eschscholtz's name on the previously undescribed California poppy. Later Eschscholtz returned the favor by naming Lupinus chamissonis after his friend. More here.]

[from the Greek krypto, "to hide, hidden," and anthos, "flower," and thus meaning "hidden flower," a reference to the first known species which had small inconspicuous flowers which self-fertilized without opening]
