Observations of two plantains

English plantainHere’s a typical plantain found around the world — usually in waste places, or lawns where it is regarded as a weed.  This is English plantain (Plantago lanceolata).  Another plantain found in similar locations is the Common plantain (Plantago major).

English and common plantain leavesBoth plants have leaves with parallel veins — an identifying characteristic.

Let’s look at another specimen of Common plantain.  Notice the flower spikes arising from the basal rosette.

Common plantainTurning back to English plantain (Plantago lanceolata), its flower spikes also arise from the basal rosette.

The flowers on the English plantain inflorescence also mature from the bottom to the top.

And here’s a very close view of those flowers which are so familiar to many of us . . .

So what’s going on here?  It looks like the first type of English plantain inflorescence consists of staminate flowers.  The little white “flags” are the anthers (at the end of the stamens) which carry the pollen.  The last two sets of images show a pistillate inflorescence  — with a single white pistil extending as a fine thread from each flower.

According to John Andrew Eastman in The Book of Field and Roadside: Open-Country Weeds, Trees and Wildflowers:  “Flowers may be pistillate (all female), staminate (all male), or bisexual — but all flowers are the same on an individual plant.”  Aahh, this confirms the observations and related conclusions!

    We used to call the English plantain “shooter weeds”. If you pick one with a long stem and wrap the stem over itself at the base of the inflorescence, pinch the loop together and pull , the head flies off and travels several feet. Hard to aim, though!

    Jane, we did the same with the plantain stems.
