|Irena in springtime|
A dense thorny shrub, the irena produces small, elongated, very sour-tasting, red fruit in summer. Much liked by animals, especially bodocs, these berries are consumed by the Matis only in the form of a sweetened marmalade since they are inedible when raw.
Its thorns can be crushed to recover an astringent substance. Its trunk is robust, but its branches are not, breaking at the slightest pressure.
