Dear all,
The naturally occurring dominant leggy shrub which dominates
many inland swamps is Lignum. It has had a few name changes over
the years. Plantnet gives Duma florulenta as name, plus
Muehlenbeckia florulenta as synonym. Earlier names include
Muehlenbeckia florulenta and Polygonum cunninghamii.
I'm guessing but I assume the name comes from the polygonous
(trigonous in fact) shape of fruits.
Isobel.
