Comprehensive Description

    Rafinesquia neomexicana
    provided by wikipedia

    Rafinesquia neomexicana is a species of flowering plant in the Asteraceae family (Commonly called the Sunflower Family[2] or Daisy Family). Common names include desert chicory,[2] plumeseed, or New Mexico plumeseed.[1][3] It has white showy flowers, milky sap, and weak, zigzag stems, that may grow up through other shrubs for support.[2] It is an annual plant (completes its life cycle in a single season) found in dry climate areas of the southwestern deserts of the US and northwestern deserts of Mexico.[2]

    Distribution

    In the United States the species occurs in California, Nevada, Utah, Arizona, New Mexico and Texas.[1] It occurs in the Mexican states of Baja California and Sonora.[4]

    It is found in the Mojave Desert, and in the Sonoran Deserts including the Colorado Desert sub-region.

    It occurs in sandy or gravelly soils in creosote bush scrub and Joshua Tree woodland plant communities in the Mojave Desert and Sonoran Desert, from California to Texas and northern Mexico.[2]

    Description

    The annual plants are gray-green with sparse foliage and are between 15 and 50 cm high.[3] Basal leaves are 5 to 20 cm long and pinnate with narrow lobes while leaves further up the stem are smaller.[3]

    White flowerheads appear at the end of the stems between May and June in the species native range.[3]

    Flower heads occur singly at the tip of branches.[2] The flower heads are composed of strap-shaped ray flowers, growing longer toward the outer portion of the head, and collectively creating the appearance of a single flower as in other sunflower family plants.[2] The outer flowers in the head extend well beyond the 1/2" to 1" long phyllaries (bracts enclosing the flower head before opening).[2]
