Subject: why separate male and female function by years?

Q.:

Susanne maintains:

Other aroids manage to achieve the same effect by less striking temporal
separation of male and female function.  If it's enough to separate polle=n
release and stigma receptivity by days or hours, why separate by years?
Are arisaemas living under such stressed conditions that they can't affor=d
to be female most years?
