Sorry I was out of the discussion about P. hastatum but as I have done
some studies on this species I felt confortable to send a description from
a paper on P. hastatum (nomenclature) by Simon Mayo and myself ( in print at
the moment). By the way, I wouldn't say that P. hastatum could present the
variation you mentioned.
All the best, Cassia Sakuragui.
