Collected in June 2004 near border between Cundinamarca and Tolima, near Melgar, south of Bogota, at an altitude of 700 m [warm-growing]. The striking, solid magenta flowers are medium-sized and not fragrant.

"Seed is yellow to the naked eye, and free flowing. Moderately large seeds are long and thin, sometimes curved, and have moderately large sized elongated yellowish-green embryos centrally located which are 1/3 the length of the seed when present. [About] 48% appeared to have good embryos."
