NOTE: There is a lot a
confusion about this species, hunt consider it a form
of
M. perbella
which forms dense
clumps by dichotomous division, but it is clearly evident from the
photos showed in the original description by Craig that they are not
exactly the same. The M. cadereytensis is actually
considered (Pilbeam) a short spined variant of M. parkinsonii.
