Character and description of Kingia, a new genus of plants found on the south-west coast of New Holland, with observations on the structure of its unimpregnated ovulum, and on the female flower of Cycadeae and Coniferae is an 1826 paper by botanist Robert Brown. Though nominally a formal description of the then-unpublished genus Kingia, it is more notable for its digressions into ovule anatomy and development, in which Brown sets out for the first time the modern understanding of the structure of angiosperm ovules, and publishes the first description of the fundamental difference between angiosperms and gymnosperms. Of the latter it has been said that "no more important discovery was ever made in the domain of comparative morphology and systematic Botany".
