Pycnandra acuminata is a species of plant in the family 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 blue in colour due to the nickel content. The vernacular name in French is sève bleue.
