Jane:
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.

Your cuatrecasasii looks like rupicola to me.

Compared to plants I am growing under the name N. rupicola, this
"cuatrecasasii" is much taller (about twice as tall) and has leaves only
about half as wide. The floral tube is quite a bit longer, too. Also, all
my accessions of N. rupicola flower at least a month later than this plant.
However, all the anthers are within the tube, which is not supposed to be
true of N. cuatrecasasii (I think).
The two species are in the same section, of course.
