Pycnandra acuminata
Species of shrub
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. It is the only known plant with turquoise sap. An excellent photo can be seen at. The vernacular name in French is sève bleue.
