The Antennaria parlinii complex consists of two fairly distinct subspecies that differ in induments of basal leaves (tomentose in subsp. fallax; glabrous in subsp. parlinii) and other characters (R. J. Bayer and G. L. Stebbins 1982). Antennaria parlinii is the most common eastern North American species (Bayer and Stebbins 1982, 1983). This complex of polyploid sexual and apomictic populations is the result of multiple hybridizations among sexual diploid species including A. plantaginifolia, A. racemosa, and A. solitaria (Bayer 1985b; Bayer and D. J. Crawford 1986). A. Cronquist (1945; H. A. Gleason and Cronquist 1991) included A. parlinii within his circumscription of A. plantaginifolia. By not including the hybrid poly-ploid within the circumscription of a single one of its sexual progenitors, the circumscription here better portrays the evolutionary relationships between A. parlinii and its sexual progenitors.

Antennaria parlinii

fornecido por wikipedia EN
Antennaria parlinii is a North American species of flowering plants in the family Asteraceae known by the common name Parlin's pussytoes. It is widespread across eastern and central Canada and eastern and central United States, from Manitoba to Nova Scotia south as far as Texas and Georgia.[2][3]
Description
Antennaria parlinii is an herb up to 45 centimetres (18 in) tall. Male and female flowers are borne on separate plants; in some populations all the plants are female. White flowers bloom April to June, with 4 to 12 or more flowerheads on a cluster at the top of the stems.[4] The common name refers to the resemblance of the flowers to the toes of a cat.[5] The basal leaves are 2.5–9.5 centimetres (1–3.75 in) long and up to 4.4 centimetres (1.75 in) wide. A. parlinii is very similar to the species Antennaria plantaginifolia (plantain leaf pussytoes), although the flowers of A. parlinii" are larger. [4]

Antennaria parlinii subsp. parlinii
The species is named for American botanist John Crawford Parlin (1863–1948), who recognized the uniqueness of the species.[6][7]
Habitat
It grows in dry, rocky areas in full sun to partial shade. It prefers acid soil.[8]
