I agree with Gene on this as a rule of thumb. . Most arisaemas have the l=eaf
petiole and the flower peduncle arising from the pseudostem, which, howev=er,
is sometimes quite short and could lead to confusion. Also, as Gusman poi=nts
out in his book, evergreen species, such as A. omkoiense, don't follow th=at
rule.

My reference to foliage was to distinguish A. dracontium from Pinellia
tripartita, where there is an obvious difference in the leaflet number an=d pattern.
However, Pinellia pedatisecta and A. dracontium are quite similar except =for
the absence of the pseudostem in the Pinellia. In fact, an "A. dracontium=" that
I received recently and seemed to be growing with remarkable vigor has
"morphed" into a P. pedatisecta!
