Compared to many petiolaris sundews, it has wide petioles, which are densely covered in silvery hairs.

Each plant has numerous leaves, which as typical for the subgenus consist of a long, hairy petiole supporting a nearly round lamina.

The lamina is densely studded with stalked mucilaginous glands, which serve to attract and trap arthropod prey, which is subsequently digested and absorbed by the plant as a source of nutrients.

During the dry season, the plant produces smaller, somewhat dormant leaves which are protected by their dense covering of silvery hairs.
