Type : D'après
The Linnean Plant Name Typification Project.: "There appear to be difficulties with this name. It has traditionally been applied, as
Pennisetum polystachion (L.) Schult., to a widespread weedy species of which several specimens are present in LINN. However, Merrill (Interpret. Rumph. Herb. Amb.: 91. 1917) clearly accepts the Rumphius plate as the type of this name (which he treats as a synonym of
Setaria flava (Nees) Kunth, an entirely different species). A number of authors have indicated material in LINN as the type but most failed to distinguish between sheets 80.4, 80.5 and 80.6. Van der Zon (in Wageningen Agric. Univ. Pap. 92-1: 335. 1992) treated 80.4 as the type but his choice is clearly pre-dated by that of Merrill. As the Linnaean epithet is pre-occupied in
Setaria by
S. polystachion Schrad. ex Schult. (1824), Merrill's typification does not result in the displacement of any name in use in that genus. However, if the traditional usage of the Linnaean name as a species of
Pennisetum is to be maintained, it appears that a conservation proposal will be necessary."
