The leaves grow opposite to half-opposite, the stem is between 15 and 30 cm long. The leaf blade is triangular to broadly ovate and up to 12 cm long, the end of the leaf is pointed, the base of the leaf is incised to heart-shaped and equilateral to unequal. The leaf margin is smooth or slightly three-lobed to deeply fingered. The cutting depths of the individual leaf fingers range from 0–90%, the segments themselves, in turn, are often wavy.

Generative characteristics

The inflorescence is multi-flowered and towers above the foliage, the stem is up to 50 cm long. The bracts are linear to obverse-lanceolate. The flowers give off a strong scent of musk . The flower stalks are up to 15 mm long. The prophylls are 2–4 cm long, the sepals 10–24 mm long, the sepals are free-standing to 50–75% of their length. The corolla is 45 mm long and is lavender-colored on the inside with rust-red to dark purple spots that are distributed in the entrance area. There are also yellow sap marks on the inside of the corolla . On the upper lobes there is a large, purple blotch, on the middle and lower, lavender lobes, there are purple stripes and spots.

Systematics

Proboscidea triloba was first described as Martynia triloba in 1830 by the German botanists Diederich Franz Leonhard von Schlechtendal and Adelbert von Chamisso . In 1865 Joseph Decaisne placed the species in the genus Proboscidea . It looks quite similar to Proboscidea fragrans and its two subspecies are allopatric .
