Coriaria arborea

''Coriaria arborea'', one of several species called tutu, is a common, highly poisonous shrub native to New Zealand.

''C. arborea'' is found in scrub and open areas from the coast to the hills across the country. A straggling plant, it can grow to 20 ft high. The leaves grow opposite on slender stems while flowers are arranged in drooping racemes.

Tutu is capable of nitrogen fixation.
