    the first picture shows the reproductive spore bearing stalk. it is called a strobili (the conelike part at the top). the second is a new vegetative stalk that will open up to be picture 3

    Thanks a lot. That clears up my long standing puzzle.

    Pic #2 had two species; the thick stems with dark brown scale leaves and just starting to expand are Equisetum telmateia, the slender stems more fully expanded are Equisetum arvense.

    Pic #1 also has Equisetum arvense shoots, this time with strobili of Equisetum telmateia.

    Pic #3 is all Equisetum arvense.
