Re: Zamioculcas zamiifolia

The info on the page about Zamioculcas zamiiofolia is specific to that plant.  I explain the differences in stems and petioles as well as the differences in tubers, corms and bulbs here:

Dylan Hannon just explained the difference in the petiole and the rachis and I will be working on the page as soon as time permits to update the info.  The petiole grows from tuberous roots which is not a true tuber.  At the point where the leaflets begin to join the stalk the petiole becomes a rachis and is a somewhat unususual form of a compound leaf.  I am corresponding with Dylan now to make sure I get all the info correct.

  Although growers that are family with plants such as a Philodendron would likely call the petiole the "stem", in the case of this species the true stem is an underground rhizome(...)
what about the climbers who put out roots on a thick trunky stem...and then a leaf-stem with a highly divided actual leaf.
