Genus Cymopterus Parsley Family (Apiaceae/Umbelliferae)
One of my books describes this plant as looking like a crumpled
doily. In this stage the plant lies quite flat on the ground, and
could be covered by your hand. The leaves are gray-green.
The individual flowers are very tiny, but many of them grow together
in a rounded clump (umbel).
After the flowers have faded and the seeds begin to mature, the
stem elongates and lifts the whole upper part of the plant several
inches above the ground. (The Latin species name longipes
means "long foot".)
The flower stems also elongate, lifting the maturing fruits even
higher above the main body of the plant.
This helps the seeds to disperse.
The plant has a fleshy taproot, which is edible. It was utilized
as food by many western Indian tribes.
