Bearded cryptantha
Cryptantha barbigera var. barbigera
Boraginaceae

According to Curtis Clark at Cal Poly Pomona and others, the name Eschscholtz was originally spelled Escholtz in German, but when it was transliterated into the Cyrillic alphabet by relatives of his who spent time in Russia, it became Eshcholts which had an 'sh' and a 'ch' sound both of which were expressed by the same Russian letter, and thus when converted back to German the 'sh' and 'ch' became 'sch' twice and the name became Eschscholzia. The 't' was dropped because Adelbert von Chamisso who published the name in 1820 Latinized the name as Eschscholzius. In those days spelling was not the more rigid system in use today, and people's names were often spelled in various ways. Even Chamisso in different places gave the name as Eschscholzia, Eschscholtzia and Eschholzia. This accounts for alternate spellings such as with Arabis eschscholtziana.
