I have just tried the same experiment (CP Digest 1734) with D. spatulata
NZ alpine form.

The glands required more stimulation and a heavier force to effect gland
movement. This movement was much slower than in D. pygmaea with the
glands moving through 90 degrees in about 10 sec. The glands moved
faster and through a larger arc if the whole length of the gland was
continuously stroked (heavily).
