Melanotrichus boydi (syn. Orthotylus boydi) is a species of plant bug in the family Miridae.It is notable as the only insect that is known to feed exclusively on a plant which hyperaccumulates nickel, specifically the milkwort jewelflower Streptanthus polygaloides. [1]
Presence of nickel in the part of the fruit covering the radicle and in the radicle itself. [14] Ni: 1000: Shorea tenuiramulosa (Dipterocarpaceae) Philippine tree: Proctor et al. .

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.

Over a hundred species in the family accumulate heavy metals, particularly zinc and nickel, which is a record percentage. [18] Several Alyssum species can accumulate nickel up to 0.3% of their dry weight, and may be useful in soil remediation or even bio-mining. [19] Brassicaceae contain glucosinolates as well as myrosinases inside their cells.
Rinorea niccolifera is a species of plant in the Violaceae family.. The plant was discovered on the island of Luzon in the Philippines, and described in 2014. [1] It is known for its ability to bio-accumulate nickel. [2]
Highly sensitized persons may also react to foods with high nickel content. [145] Patients with pompholyx may also be sensitive to nickel. Nickel is the top confirmed contact allergen worldwide, partly due to its use in jewelry for pierced ears. [146] Nickel allergies affecting pierced ears are often marked by itchy, red skin.
Nickel ions can act as a cation in salts with many acids, including common oxoacids. Salts of the hexaaqua ion (Ni · 6 H 2 O 2+) are especially well known. Many double salts containing nickel with another cation are known. There are organic acid salts. Nickel can be part of a negatively charged ion (anion) making what is called a nickellate.
The flavor and aroma of its seeds have similarities with some other spices and herbs, such as star anise, [4] fennel, liquorice, and tarragon. It is widely cultivated and used to flavor food, candy, and alcoholic drinks, especially around the Mediterranean .
