 Comments
       
  Comment: According to California Academy Catalogue of Diatom Names, Navicula directa (W. Smith) Brebisson 1854 and N. directa (W. Smith) Ralfs in Pritchard 1861 are nomenclatural synonyms (specifically, isonyms), as both were based on Pinnularia directa W. Smith. Witkowski et al. 2000 reported this taxon as the latter
