were hundreds of white Calochortus (venustus ?) and a few yellow (luteus?).

Check out the gland (the hairy nectary at the base of the petal) on the
white ones. If it's square, they're probably C. venustus. If it's crescent
or V-shaped, they're probably C. argillosus. Around Almaden I've found only
argillosus, with a wide variety of gloriously complicated markings in pink
and yellow. I've seen plants that looked like C. venustus in the east hills
(Mt. Hamilton).

Hope that's useful.
