  Re: [Aroid-l] Thorns at anubiases

Dmitry,

Are these thorns associated with the stem adjacent to the leaf or are they
part of actual leaf (petiole, petiolar sheath, etc.)

My suspicion is that they either are epidermal outgrowths (i.e., prickles)
of the sort often associated with the lasioids or perhaps toughened roots
(so-called root-thorns) that occur in some aroids (notably Pothos and
Phymatarum).

Very best

Peter
