Spiked centaury (Schenkia spicata)
Description
Schenkia spicata is a species of annual herb in the family Gentianaceae. It has a very wide old world distribution, ranging from north Africa, through Europe and into Asia. It was first published as Gentiana spicata by Carl Linnaeus in his 1753 Species plantarum. It was later transferred into Erythraea and then Centaurium, under a broad circumscription of the latter genus that was subsequently found to be polyphyletic. In 2004 Centaurium was split into four genera, with C. spicatum becoming Schenkia spicata. At the same time, it was noted that European and Australian specimens ascribed to this species are in fact different taxa; for example, all Australian specimens studied were tetraploid, whereas all European specimens studied were diploid. Therefore the Australian specimens were segregated into a new species, Schenkia australis.
