location Mountain Palm Spring, south of town of Canebrake, Anza-Borrego Park (San Diego County, California, US)plant community Desert Scrub.notes This image show two flowers and numerous buds of Krameria grayi. There are two species of Krameria in the Jepson Manual: K. erecta and K. grayi. In both species, a novice might mistake the showy purple sepals for petals. But the actual perianth is a bit strange. The five 'petals' consist of three upper petals (above the pistil and stamens) and two distinctly different 'gland-like' petals (lateral to and somewhat below the pistil and stamens). In the flower of K. grayi the purple-tipped, yellow, upper petal blades are thinner, straigher (i.e. more erect!), and almost parallel and touching. Whereas in K. erecta, each upper petal blade is wider (i.e. the petals are clawed), and the three of them are more fanned-out laterally when viewed straight on. Also, the two 'gland-like' lower-lateral petals of K. grayi have the surface texture of a bunch of small balls fused together, whereas the the 'gland-like' lower petals of K. erecta are textured with low, more or less parallel, longitudinal ridges. When not in flower, the two species can be distinguished (using a hand lens) by their fruit. Both have small hairy more or less spheric fruits covered with spreading spines. On K. grayi, the fruit spines are barbed only near the tip, while on K. erecta the barbs are scattered all along the fruit spines (or lacking).camera Shot at f5, 1/200 sec on Canon D60 with a Canon 50mm Compact Macro lens.photo category: Plant - shrub
