15768 from Ecuador differ from the type in having sepals that lack fleshy trichomes. They always have 3-lobed leaves and the corolla is relatively small, being 5-6.5 cm long. Specimens from Mexico have 5-9-lobed leaves, a large corolla up to 10 cm in length and sepals densely covered in soft spines.
