homotypic synonym, validly published under the ICN (Botanical Code)
Notes:
❗ Spirulinaspirulinoides f. tenuis is the correct name instead if this form is regarded as a separate form (i.e., if its nomenclatural type is not assigned to another form whose name is validly published, legitimate and not rejected and has priority) within a separate species Spirulinaspirulinoides within a separate genus Spirulina.
