Derivation of the botanical name:
Anagallis,(given by Dioscorides) from the Greek Anagelao, signifying 'to laugh,' from its use in treating depression.
arvensis, arvum, field, cultivated land, plowed land; ensis adjective suffix for nouns: country or place of origin or habitat. MeaningL: "of cultivated fields".
Pimpernel is from the Latin bipinnella, applied in the sixteenth century to plants with bipinnate leaves.
Several of the common names, " Shepherd's Barometer and poor man's weatherglass", relate to weather forecasting, since the flowers open and close with changing weather.
