[Aroid-l] Homalomena - what's the name of these fibers?

From: "Marek Argent" <abri1973 at wp.pl> on 2011.06.02 at 00:17:10

Hello,

I cut a stem of Homalomena (probably rubescens).

The stem was about 2 cm in diameter.

These wood-like fibers are very hard to cut or tear.

I know that they help the stem to stay in horizontal position and to be elastic

I have never seen such a structure in any other aroid's stem.

In leaves of Monsteroideae (except Amydrium) similar fibers are named trichosclereids,

What is their name in the stem? (photo attached)

Best,

Marek
