Type not relevant. Current name: Phragmites karka (Retz.) Steud. ( Poaceae ). Note: Veldkamp (in Blumea 37: 232-233. 1992) has argued that " Arundo vallatoria Pluk. ", from the right-hand column of names in the thesis Herbarium Amboinense (1754: 15), is a valid Linnaean binomial based on Rumphius' 4: t. 5, and an earlier name for the plant known as Phragmites karka Retz. He therefore made a new combination for it as P. vallatoria (Pluk. ex L.) Veldk. However , it seems clear that Linnaeus was merely citing " A. vallatoria, Pluk., Mant. 28" as a synonym of Rumphius' plant, the binomial form of Plukenet's name being merely a coincidence. Apart from the reprint of the thesis ( Amoen. Acad. 4: 115. 1759), Linnaeus never used the name again, and it is in any case invalid (see Art. 34.1, Ex. 2).
