Opuntia schumannii is described by Berger as being intermediate between Opuntia 

 and Nopalea, and according to him, it has long stamens and upright petals; otherwise it 

 has little in common with Nopalea: a plant from Santa Clara, Colombia, which agrees 

 with plants of 0. schumannii from La Mortola, Italy, has a normal Opuntia flower.
