Synonyms:

  • Narrowleaf Plantain
  • Ribwort Plantain
  • Arnoglossum lanceolatum S.F. Gray
  • Plantago altissima, of authors not L.
  • Plantago lanceolata var. sphaerostachya Mert. & Koch

Comment:

This non-native plant, found everywhere in the US as a weed, has some medicinal uses. The tiny four-petaled flowers on the flowering spikes each produce four stamens with white anthers which dance in the wind.

In Ultraviolet light the petals are UV-absorbing.
