Frankia Brunchorst 1886, genus. (Type genus of the suborder ¤ Frankineae Stackebrandt et al. 1997; type genus of the family ¤ Frankiaceae Becking 1970 [Approved Lists 1980]).
Type species: ¤ Frankia alni (Woronin 1866) Von Tubeuf 1895 (Approved Lists 1980).
Synonym: "Frankiella" Maire and Tison 1909.
Etymology: N.L. fem. n. Frankia, named after Albert Bernhard Frank (1839–1900), a Swiss plant biologist, who studied extensively nitrogen nutrition in legumes and the micro-organisms causing root nodulation from 1877 to 1892 and who coined the term "symbiosis".
