Strawberries vs. Cinquefoils

I recently stated that woodland strawberry (Fragaria vesca) and sticky cinquefoil (Drymocallis glandulosa) could be confused if one were to ignore the prominent flower spikes on the Cinquefoil. While hiking on the Santa Ana River Trail I came across a large patch of Fragaria with prominent flower spikes. "Oh no," I thought, "this can't be Fragaria." And it wasn't. Phew.  Apparently they like the same growing conditions and happily intergrow.  The opportunity to look at them side by side gave me new insight into their differences and they aren't so close in appearance that they can't be distinguished by a keen observer.

Above is a picture of a Strawberry leaf (upper right - three somewhat elliptical leaves touching at the stem end) and three leaved of Cinquefoil (lower left - rounder leaves lighter in color and not touching at the stem end).

A patch of Fragaria is always low-growing.  The tallest spike in the above photo is somewhat out of focus at center front.  It has to be all of 4" tall.

Cinquefoil leaves on a stalk. It goes up and up to where the flowers are:

Cinquefoil has these characteristic flower stalks.  I haven't seen any in the prime of flowering, only with these typical dried blooms.
