My triph's runners are just like the ones George described, forming a new
little tuber at the end. I've got tri's everywhere in the yard and indoor=s,
including various stages of refridgeration (I especially like to force po=ts
of them for Halloween decorations). They've gone bonkers for me in any ri=ch
soil and will tolerate rougher exposure if kept very moist - full sun and
less than perfect soil. My cons's, purchased and seed grown, were in
Scott's potting soil/ perlite mixes but are now all outdoors in the leaf
mold and manure ammended local sandy soil.
I havent seen Arum italicum runners, but it, like Sauromatum venosum,
produces loads of minute break-away and "roll-away" offsets, probably in
response to wild pig herbivory. So whenever you dig around one of these, =be
prepared to find babies popping up all over your garden. This is also
probably great for an aroid that colonizes leaf litter on steep slopes.
Look in the archives for my communiques on tubers buried in deep autumn
litter sprouting in spring in moist fertile leaf mold and having newly
formed tubers half exposed in summer as the former said leaf mold seaming=ly
sublimates into the sandy soil beneath, keeping the tuber from rotting in
the summer rains.

Bonaventure.  How long are these stolons?  I suspect something of the sor=t
with my Arum italicum., but havenn't dug it up or exposed the roots to se=e.
Your observation is going to prompt me to check,.  Also, what kind of soi=l
do you grow your triphyllum and consanguineum in?    Probably not clay
right?  --doesn't make stolons easy.

Re:  observations about growing in forest litter  in nature.  Is this
strictly true, or are the roots in underlying cla, like some terrestrial
orchids where litter overliess the root system, but the tubers are anchor=ed
in clay, or rocky soil.>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
