Ambrosia deltoidea

Ambrosia deltoidea is a shrub growing from a taproot with many lateral and adventitious roots. The plant produces many thin branches growing up to about half a meter tall. It generally has many dead branches tangled in the living crown. It is drought-deciduous. The leaves are no more than 2 centimeters long. The branches and new leaves are coated thinly in woolly fibers; the leaves become hairless with age.
The inflorescence is a spike of several staminate flower heads. There are often some pistillate heads just below these, with some pistillate heads borne on lateral branches. The fruit is an achene covered in spines. The achenes are usually dispersed when they stick to animals. The plant has been observed to have a lifespan of about 50 years.
