Dear Margret and Dieter,
I do not believe that true 'branching' can take place in any aroid. As Peter Boyce explained, new entire leaves w/ petioles are produced from a previous leaf sheath or cataphyll which is always located at the base of the previous older petiole/leaf, or in the case of some cataphylls on the apex of a dormant tuber.
No aroid produces a new leaf from any area of a previous petiole except from the sheath at its base. No photo came with your posting.
>>Some weeks ago, we observed on one of our Am. bulbifer
that a second petiole emerged about 4 cm above the soil
from the existing petiole. Later, this second petiole broadened
downwards, as shown on the picture. The arrow indicates
the original emerging point. Hence branching of petioles is
possible within the genus Amorphophallus and, as Wilbert
wrote to us, is also known e.g. from A. paeoniifolius and
