Lasjia

Lasjia is a genus of six species of trees of the family Proteaceae. Three species grow naturally in northeastern Queensland, Australia, and three species in Sulawesi, Indonesia. Descriptively they are the tropical or northern macadamia trees group. Lasjia species characteristically branched compound inflorescences differentiate them from the Macadamia species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about further to the south, in southern and central eastern Queensland and in northeastern New South Wales.

The Bama aboriginal Australian peoples in the late 1800s Bellenden Ker Range rainforests (north east Queensland) taught European–Australian scientists of L. whelanii trees bearing the large seeds "extensively used for food". One of those scientists, colonial botanist Frederick M. Bailey, collected and in 1889 formally published a scientific description of specimens of them under the name Helicia whelanii and later again in 1901 as a species of Macadamia. Of these five Lasjia species, it was the first to receive a European–Australian scientific name.
