Krameria erecta (Pima rhatany) is a native California shrub in the Krameriaceae family, recognized by key differences are growth habit, branch tips, and fruit shape.

Pima rhatany is a California native perennial found in the eastern Peninsular Range, including the Santa Rosa Mountains, and desert regions on dry, rocky ridges and slopes at elevations below 1,200 meters. Flowering from March to May, this plant produces magenta sepals and yellow to green flag petals with distinctive purple markings. Growing with strigose or silky-hairy stems up to 2 meters tall and often with ascending branches, it has a distinctive branching structure. Its leaves are approximately linear to lance-linear, sparse and narrow. The fruit is uniquely cordate and slightly flattened, reflecting the plant's intricate desert adaptation.
