Tree violet

Melicytus dentatus, commonly known as the tree violet or hinau, is a native New Zealand shrub or small tree belonging to the violet family (Violaceae). This evergreen plant is found in various habitats, including lowland and montane forests, and it is valued for its ornamental qualities. Here's an informative description of Melicytus dentatus:

Appearance:

• Habit: Melicytus dentatus typically grows as a shrub or small tree, reaching heights of 5 to 10 meters.
• Leaves: The leaves are dark green, glossy, and toothed along the margins, which gives rise to its specific epithet "dentatus" meaning toothed. The leaves are elliptical to oblong and arranged alternately on the stems.
• Flowers: Inconspicuous flowers are produced, often with a greenish-yellow color. The flowers are small and can be either male or female, with some plants being dioecious (separate male and female plants).
• Fruit: The plant produces small, berry-like fruits that turn purple when mature. These fruits are an important food source for native birds in New Zealand.

Identification:

Identifying Melicytus dentatus involves recognizing its glossy, toothed leaves, small greenish-yellow flowers, and distinctive purple fruits. The toothed leaf margins are a key feature in differentiating it from other Melicytus species. Botanical field guides specific to New Zealand flora or consultation with local experts can aid in accurate identification.
