Boerhavia wrightii is a species of flowering plant in the four o'clock family known by the common name largebract spiderling.

This is an annual herb producing a slender, spidery erect stem to about 70 centimeters in maximum length.

The leaves are lance-shaped to oblong with rippled edges and roughly pointed ends.

The inflorescences appear at the ends of the slim stem branches.

They bear a few pale pink flowers, each just a few millimeters long, with adjacent reddish or pinkish bracts.
