Metrosideros umbellata, the southern rātā, is a tree endemic to New Zealand. It grows up to 15 metres (49 ft) or more tall with a trunk up to 1 metre (3 ft 3 in) or more in diameter. It produces masses of red flowers in summer. Unlike its relative, northern rātā, this species rarely grows as an epiphyte.
