How to tell it
A thornless shrub or small tree with large alternate leaves, oval and glossy, with eight to twelve pairs of very straight parallel veins, the genus's mark. Discreet green flowers at the axils. Green, red and black berries at once on the same branch. Range: endemic to the Azores.
What it is confused with
Alder buckthorn
Frangula alnus
They are very close and share the parallel veins and tricolour berries. Geography separates them: alder buckthorn is mainland, this exists only in the Azores. Both are strong purgatives.
Open sheet →What it is for
None. Like mainland buckthorn it contains anthraquinones and is a violent purgative: the berries cause vomiting and severe cramps and are never eaten. It is a protected and declining species in the Azores.
The law says
A species protected under the Habitats Directive. Do not cut or collect it.
