Other: The genus name, “Sophora”, is from the Arabic “sophira” which is the name of a tree with pea-shaped flowers. The species name, “stenophylla”, means “narrow-leafed” coming from the Greek stenos which means “narrow” and “phyllon” which means “leaf”.
This family is ranked second to grasses in importance to people because species can fix nitrogen. However, some species, e.g., locoweeds and milkvetches, are poisonous due to selenium abstracted from the soil.
Did You Know?
Lizards, including the colorful collared lizard, are one of the most frequently seen animals at Arches. When not chasing flies or basking in the sun, they are often seen doing what appears to be push-ups. This odd dance might enhance their stereoscopic vision, helping them see what's looking back at them.
