Hornstedtia scottiana, common known as Scott's ginger, jiddo, or native cardamom, is a very large ginger (member of the family Zingiberaceae) native to Queensland, New Guinea and the Maluku Islands.

Its fruits are eaten by the cassowary.

It is also a food plant for the larval stages of the Banded Demon Butterfly.

[3] It was first described in 1874 by Ferdinand von Mueller as Elettaria scottiana from a specimen found in the rainforest in Rockingham's Bay by John Dallachy.

[1][4] In 1904, it was redescribed as belonging to the genus, Hornstedtia, by Karl Moritz Schumann.
