Booth's sun cup

Family: Onagraceae · Type: annual · Native

Booth's sun cup is a California native annual found in rocky or sandy habitats at moderate elevations. Flowering from March to June, this plant produces white to red-tinged flowers small to 7.5 millimeters long, with a distinctively nodding inflorescence. Growing with generally red-tinted erect stems that peel and have sparse minute hairs, it develops a sparse or occasionally well-developed rosette. Its leaves are lanceolate to narrowly elliptic, sparsely toothed, with proximal leaves sometimes oblanceolate or absent. The fruit is notable for being 8 to 35 millimeters long, cylindric, and curved or twisted, with seeds that vary from pale to dark brown.
