snake-plantain

Updated: May 25, 2025

Ascidia of the snake-plantain or Plantago lanceolata are narrow tubes, because the leaves are oblong or lanceolate, while those of the broad leaved species of arrowhead, as for instance, the Sagittaria japonica, are of a conical shape. From the evidence of the lime-tree we may conclude that normal peltate leaves may have originated in the same way.
