Species Huernia blackbeardiae

For Justus Heurnius (1587–1652), Dutch missionary, doctor and an early collector at the Cape, South Africa. His drawings constituted the iconotypes for Stapelia, which is what the first taxa of Huernia was described as. He was the author of De Legatione Evangelica ad Indos capessenda admonitio (1618) and discovered Orbea variegate at the Cape in April 1624, while on his way to Batavia (present-day Jakarta) as a missionary. In 1639 he returned to the Netherlands, where he became a minister at Wijk bij Duurstede and helped to translate the Bible into Malay. The genus name Huernia was misspelled by Robert Brown, who published it in 1810.
