Microphoto of rootlets of a palm: Rhizopalmoxylon.
Finding place: Ellertshaar (NL). Width of the photo 6 mm.
The central cylinder of the roots has decayed in most cases. That is because the inside
of the bark consists of sclerenchyma cells and is therefore nearly impermeable to water.
The rootlets are often pressed together.
Coll. Derk ter Heide, Westerbork.
