Apparently the genetics of Dieteria canescens allows certain plants to have no marginal ray flowers. The Jepson Manual says heads 'gen' radiate. Many of the plants we observed in this area were lacking in ray flowers, which confused us at first and made it difficult for us to identify them.The first publication of the name Dieteria was in 1840 in Trans. Amer. Philos. Soc. by Thomas Nuttall in which he says "So-called from their biennial duration." The name is derived from the Greek di-, "two or twice," and etesios, "yearly, annual." His description of the genus however says "annual or biennial (in one anomalous species perennial)." The pictures below show plants that did have ray flowers.
