Dear Steve,

I can only guess that they call rhachis the part of the leaf with leaflets, as they describe that the petiole is 15-35 cm long. My plant's total leaf length is up to 120 cm. So possibly the petiole is the thick part without leaflets and the rhachis is the rest of the leaf.

Look here: http://www.thefreedictionary.com/rachis

"Botany the main axis or stem of an inflorescence or compound leaf"

In your page I would rather change "Philodendron" to "Amorphophallus" - a majority of the amateur growers of Amorphophallus call the petiole "stem".

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(...)
