Descriptions

Landrum (1999)
Marticorena & Rodríguez (2003)

Habit

Deciduous shrub to 1.5 m, Flowering from November to January and fruiting from January to March.

Key characteristics

B. rotundifolia is part of a complex of species related to B. actinacantha but differs by having leaf
margins nearly all entire, with only a few teeth sometimes present; peduncle plus rachis (if any) of inflorescence 1-4 cm long (Landrum 1999). The most relible character is the backward pointing, foliaceous or star-like spines.

Notes

Some forms of B. corymbosa of Isla Mastierra (Juan Fernández Archipelego) are similar in leaf shape and texture and the possibility of a relationship must be considered (Landrum, 1999)
