The filaree is a common weed which comes in two sizes.  Other than size, there is no way to tell the two species apart.  Erodium cicutarium is the smaller one, and E. moschatum is the larger.

These are the leaves of the two species.  E. moschatum above, E. cicutarium below.  The other parts of the plants show the same proportions.

Here is a closer look at the tiny flowers.  They really are rather pretty.

Here is a comparison of the fruit of the two species of filaree.

These are the mature fruit shed by the filaree.  The point has barbs.  When it penetrates fur or clothing, it works its way inward.  And the points hurt.  The twisted tail of the fruit coils and uncoils with changes in relative humidity, drilling the point into the ground.
