Eucryphia pinnatifolia Gay Eucryphia glutinosa, the brush bush or nirrhe,[2] is a species of flowering plant in the family Cunoniaceae, native to moist woodland habitats in Chile.

Single (or occasionally double) four-petalled, fragrant white flowers with prominent stamens appear in late summer.

[3][4] The Latin specific epithet glutinosa means “sticky, glutinous”.

[5] The hardiest of its genus, it is a popular subject for cultivation in parks and gardens, valued for its foliage and late flowering.

It requires moist, acidic soil with roots shaded from the sun.
