Description

Large patch of Marsh Marigolds (Caltha palustris) in bloom, growing in the headwaters area of Miller Creek. If they look like the common butter cups, they are closely related - being in the same family (Ranunculaceae). Several of the plants - lower left - have already been pollinated and you can see the trapezoidal seeds starting to form.

Interspersed among the Caltha you can see the brown fertile fronds of Sensitive Fern (Onoclea sensibilis) sticking up.

Also growing among the Caltha are young shoots of Equisetum [arvense?] (also known by the common names of scouring rush and horsetail fern).

If anyone wants to have a go at the grasses - send me an email - my knowledge of these is limited to "sedges have edges".
