Antirrhinum filipes
Twining snapdragon. filipes, "thread-footed" refers
to the tortuous, filamentous flower stalk. The flower is bright yellow.
A most handsome, climbing annual, with long, slender, bright green
stems and leaves. It climbs by twisting its filamentous flower stalks
around the branchlets of shrubs offering it protection. The early
flowers, borne about the base of the plant, are often cleistogamous,
i.e., fertilized in the bud withoud the opening of the flower.
Confined to the creosote-bush area of both deserts; east-ward of
Arizona and southern Utah.
