About Convolvulus chilensis Pers.
Convolvulus chilensis Pers. is a thinly to densely pubescent herb that grows from a thick rootstock. Its young parts may be sericeous but become more or less glabrescent over time. The stems trail (rarely twine) and can reach up to 2.5 m in length. The leaves are petiolate, measuring 2 - 8 x 2 - 6 cm, and highly variable in shape. They are usually linear or oblong with prominent, elongate, bifurcate basal auricles, but can also be ovate - deltoid to suborbicular with rounded auricles. The leaf apex is usually acute, the margin is entire or undulate, and the base is cordate to truncate. The petioles are 0.5 - 3.5 cm long. The flowers, numbering 1 - 2 (- 3), are axillary and pedunculate. The peduncles are 2 - 4 (- 6.5) cm long. The bracteoles are 2 - 4 mm and lanceolate. The pedicels are 5 - 10 mm long. The outer sepals measure 7 - 9 x 5 - 7 mm, are elliptic, obtuse, and mucronate. The corolla is 1.5 - 2.5 cm long, pink, very shallowly lobed with slightly fimbriate margins. The midpetaline bands are dark, pilose, and end in a pilose mucro. The ovary is glabrous. The style is divided 6 - 10 mm above the base, and the stigmas are 1.5 - 3.5 mm, cylindrical to linear, and unusually variable. The capsule is glabrous, and the seeds are rugose.
