Yellow Sisyrinchium?

Another possibility is Sisyrinchium exile.  It too is an annual species,
introduced from South America.  It is a short plant, and the yellow flowers
have brown markings toward the center.
Currently it appears that I have a lot of pale yellow S. rosulatum in my
lawn.  In a few weeks I'll have a similar (or the same?) species blooming
with pale blue flowers.
