According to Dr. Oakeley, this Colombian species, in spite of the yellow flowers, deciduous habit and spines, is closely related to Lyc. macrophylla rather than Lyc. aromatica, cruenta or the other yellow-flowered species from Central America. It certainly flowers less abundantly for me than either aromatica or cruenta, and the scent (unfortunately) isn't anything to brag about (again, compared to the extravagant fragrances of aromatica and cruenta). But it's an easy species to grow and bloom, and the flowers are pretty. I just try to keep my nose at a respectable distance.
