Orbexilum onobrychis along Cumberland Drive

Here is a small population of French grass, Orbexilum onobrychis in a curious place, in a constructed perpetually wet ditch along Cumberland Drive near Celery Bog Park.  There doesn't seem to be any more of this in the park or elsewhere nearby.  The floating plant in the background is floating primrose-willow (Ludwigia peploides ssp. glabrescens) which is common in the pond nearby in Celery Bog Park.

Purple loosestrife (Lythrum salicaria) has been associated with this spot.
