LEAVES: Most of the leaves grow at ground level in a roseatte atop a tap root. Leaves are elyptic to linear in shape.

FLOWERS: Once flowering begins, a tall spindly stalk with a number of divaricating branches grows. The flowers opening July to September, are greenish yellow and not very showy.

FRUIT: The bracts enclosing the seed expand to form flat wings.

ANNUAL: Few plants surpass one meter in height with the flowering stalks.

RANGE: Common in Arizona's ponderosa woodlands after good summer rains.
