Distribution and habitat

  • Ehrhart (2005)


Erect shrub to 1.5 m tall and spreading to 2 m.

Key characteristics

This shrub has the shortest petioles (3-8 mm) among the species that belong to the C. integrifolia group, which is broadly winged and dentate like the auricles. Its most distinctive character is the very glutinous (sticky) leaf surface. Ehrhart (2005) maintains that C. viscosissima is most closely related to C. georgiana.


Calceolaria viscosissima forms hybrids with C. morisii

Seed of this species is banked by the national seed bank of Chile, INIA.
