Woody climbing stems of Bramble (Rubus fruticosus agg.)
Woody climbing stems of Bramble (Rubus fruticosus agg.) showing backward-pointing spines and axillary buds, about 30 cm long.
The backward-pointing hooked spines help the stem to hold onto twigs and branches as it climbs. Buds can clearly be seen in the axils of the old leaves.
Some of the longer branches eventually arch over and touch the ground. A new plantlet with adventitious roots may then develop at the shoot tip and the plant reproduces vegetatively.
