Both species are quite variable with regards, size of plant, leaves, size 
of flower, height and time of flowering.I have examined both species in 
Spain.  N. cuatrecasasii has three stamens sticking into the corona and 
there are three in the tube. In N. rupicola all six stamens are in the 
tube. In N. rupicola the opening to the tube is restricted, in N. 
cuatrecasasii it is wider. N. rupicola often has a pronouncedly scalloped 
and shallower, flatter corona like your flowers show, while in the other 
the corona is more of an acorn-cup shape.

My first N. rupicola is in flower, others showing buds while the N. 
cuatrecasasii still have to show their buds.

One definite way to tell is to remove the flower sheath. N. rupicola has 
amost no pedicel = stalk between the ovary and flower stem, while N. 
cuatrecasasii has a pedicel about 1 cm long. Check yours out and let me know.
