Antirrhinum filipes

Antirrhinum filipes (syn. Neogaerrhinum filipes) is a species of New World snapdragon known by the common name yellow twining snapdragon.

It is native to the deserts of the southwestern United States and northern Mexico. This is a hairless annual herb growing long, thin, vinelike stems which climb on objects, including other plants, for support. The inflorescence is composed of a tendril-like pedicel which may be up to 10 centimeters long and coils tightly to help the plant climb. At its tip is a single snapdragon flower which is bright yellow to gold in color, dotted with dark red, and just over a centimeter long.
