Violaceae is a family of flowering plants established in 1802, consisting of about 1000 species in about 25 genera. It takes its name from the genus Viola, the violets and pansies.
This list covers known nickel hyperaccumulators, accumulators or plant species tolerant to nickel.

Leucocroton havanensis is an endemic species to Cuba. It is located on serpentine soils and limestone rock in the western and central part of the country. It is an evergreen tree that has dioecious flowering, meaning the species has distinct male and female individuals. The plant only grows on a small serpentine island.
Nepenthes barcelonae is a tropical pitcher plant native to the Philippine island of Luzon. It is known from a single mountain in the Sierra Madre range of Aurora Province, where it grows in stunted submontane forest.
Nepenthes aenigma is a tropical pitcher plant known from two mountains in Ilocos Norte province on the Philippine island of Luzon, where it grows at an elevation of around 1200 m above sea level. The species is notable for growing among dense vegetation in deep shade. It shows similarities to N. burkei and N. ventricosa.
Pycnandra acuminata is a species of plant in the family of Sapotaceae. It is a rainforest shrub, endemic to New Caledonia, and is adapted to the nickel-rich ultramafic soils found there. Pycnandra acuminata is notable as one of the most prolific hyperaccumulators of trace metals known, actively absorbing nickel from the soil and concentrating it within the plant to a concentration of up to 25% nickel citrate as dry weight of the sap, which is turquoise-green in colour due to the nickel content. the only known plant with turquoise sap. An excellent photo can be seen at. The vernacular name in French is sève bleue.
Rinorea bengalensis is a species of plant in the family Violaceae. They are seen as understorey trees in wet evergreen forests up to 800 meters in Indomalaysia, Australia and Pacific Islands and in the Western Ghats they can be seen at Coorg and Chikmagalur Regions.
Rinorea dentata, commonly known as kuntze, is a species of plant in the family Violaceae. It is found in the tropical rainforests of Liberia, Nigeria, Cameroon and Uganda. It is particularly common in the Omo Forest Reserve in Ogun State, Nigeria.
Danilo S. Balete, also known as Danny Balete, was a Filipino zoologist and biologist. His is known for his work on the Philippines' endemic mammal species. He pursued the question of what determines species diversity. The research by Balete and his team overturned previously held notions that diversity decreased in mountainous regions, showing that harsh environments could generate, rather than suppress, species diversity.
Phyllanthus balgooyi is an herbaceous plant in the family Phyllanthaceae, found in Palawan and Sabah. The plant is a hyperaccumulator of nickel, with a concentration of the metal exceeding 16% in the plant's phloem sap.
