Description
Pantes of adult size, i.e. in age of flowering. D. intermedia is a small plant, and in my experience, its heterophyllous form is even smaller.
In the gallery, you can see the size of the hibernaculum of an adult foot (as evidenced by the floral spike on the right), with my left thumb for scale. It measures only a few millimeters, for an adult plant of one or two centimeters in diameter (outdoors and in my conditions: in the greenhouse, certainly a little more).
