Taxonomy
The genus name of Prestelia is in honour of Michael August Friedrich Prestel (1809–1880), a German mathematician, meteorologist and cartographer. He was also professor of mathematics and natural science at a school in Emden, and director of the naturalist society in Emden.[3] It was first described and published in Gen. Pl. Vol.2 on page 236 in 1873.[1] The genus is recognized by the United States Department of Agriculture and the Agricultural Research Service, but they do not list any known species.[4]
