Life cycle: Erect winter or summer annual.
Flowers and fruit: Bright yellow flowers with four petals are found in terminal clusters. Fruit are 1- to 2-inch-long, cylinder-shaped capsules with a four-angled beak at the tip that contain round, black to purple seeds.
Stems: Erect, up to 3-foot-tall stems bolt from a basal rosette to flower. Stems are bristly hairy at the base, often branched and nearly hairless at the top.
Leaves: Seedlings have smooth, kidney-shaped cotyledons and prominently veined, bristly hairy leaves that initially develop from a basal rosette. Lower leaves are irregularly lobed and toothed with petioles; upper leaves are alternate, stalkless to short-stalked with coarsely toothed margins and pointed tips, gradually becoming smaller toward the top.
Reproduction: Seeds. |

Similar weeds: Dwarf sumac (R. copallina L.) Differs by having smooth leaflet margins, raised red dots on stems and distinctly winged leaf stems.
Smooth sumac (R. glabra L.) Differs by having hairless stems and petioles and more open fruit clusters. May hybridize with staghorn sumac. |
