David's poinsettia

Family: Euphorbiaceae · Type: annual · Not Native

David's poinsettia is a naturalized annual found in the Sacramento Valley in disturbed sites at near-zero elevation. Flowering in July, this plant produces small white or green bracts surrounding tight clusters of cyathia at branch tips. Growing with erect stems 20 to 50 centimeters tall that have sparse, stiff, recurved hairs, it develops branches ascending from the base. Its leaves are alternate at the uppermost nodes and generally opposite below, with elliptic to lanceolate blades 4 to 8 centimeters long, coarsely toothed and recurved-hairy on the undersides. The fruit is a depressed-spheric, lobed structure 3.5 to 4 millimeters long, bearing coarsely tubercled seeds.
