Periploca laevigata

The cornical is a woody-based climbing shrub that can reach several meters in length. Its stems are brittle and twining, allowing it to entwine itself with other plants or climb them. Its leaves are opposite, simple, with short petioles and obovate to oblanceolate blades with entire margins. The color varies from deep green to yellow before falling in the summer when the plant goes dormant. Its flowers are not very showy due to their size, but upon closer inspection, they are quite attractive and complex, particularly the corolla, with five petals that are reddish in the center and green on the margins. Its fruits are two horn-like structures that, when ripe, split open along a line and release the seeds, which have long, silky hairs that facilitate wind dispersal (anemochory). When wounded, it secretes a characteristic white latex that helps soothe irritation caused by the latex of the cardon cactus and the tabaiba plant.
