Agoseris apargioides

A misinterpretation of the type description of Agoseris apargioides resulted in its confusion with A. hirsuta during the latter half of the twentieth century; the two species are not conspecific. Agoseris apargioides (in the strict sense) here includes what most authors of recent floras have called A. apargioides subsp. maritima and/or var. eastwoodiae. It occurs on coastal dunes along the Pacific coast from central California to Washington. A unique feature of A. apargioides is that its stems become progressively buried by drifting sand, leaving a terminal rosette of leaves exposed, the plants thus appearing pseudorhizomatous.
