Identificaciones de brodiaea_max

Photo #3 shows a distal cauline leaf.
Photo #4 shows a proximal cauline leaf.

I would say that photo #2 shows ascending sepals, which among the local mustards indicates genus Brassica.

Photo #5 shows a distal cauline leaf that is smaller with a tapered, unlobed base, which indicates B. nigra.

I'm not sure whether the cauline leaves should be called sessile or petioled, but since our local Brassica species are only sessile, I'm willing to go along with that.
