Uropappus lindleyi (DC.) Nutt.[FNA19, HC2]
linearleaf microseris, silver puffs, Lindley's false silverpuffs

Publication: Trans. Amer. Philos. Soc., n. s. 7: 425. 1841.

Origin: Native

selected vouchers: WTU

Notes: FNA19: "Uropappus lindleyi was placed in Microseris (K. L. Chambers 1955) because of two allotetraploid species formed by hybridization with annual members of that genus. A number of morphologic features, including narrow, acuminate leaves with villous-ciliate margins, erect heads, relatively long outer phyllaries, cypselae often short-beaked, and pappi of white, lustrous scales suggest a connection with Nothocalaïs, especially N. troximoides. Phylogenetic studies of chloroplast DNA variation (R. K. Jansen et al. 1991b; J. Whitton et al. 1995) link Uropappus with Nothocalaïs and Agoseris as a sister clade to Microseris. Consequently, Jansen et al. separated Uropappus from Microseris and placed the two allotetraploid species in Stebbinsoseris."
