Antennaria plantaginifolia
''Antennaria plantaginifolia'' (known by the common names Plantain Leaf Pussytoes and Woman's Tobacco)〔(Wildflowers of the United States, Plantain-leaf Pussytoes, Woman's Tobacco - ''Antennaria plantaginifolia'' )〕 is a perennial forb native to the eastern North America,〔(【引用サイトリンク】url=http://plants.usda.gov/core/profile?symbol=ANPL ) USDA, NRCS. 2014. The PLANTS Database (http://plants.usda.gov). National Plant Data Team, Greensboro, NC 27401-4901 USA.〕 that produces cream colored composite flowers in spring.
==Description==
''Antennaria plantaginifolia'' is rarely more than 15 centimeters tall, consisting of a basal rosette, and an erect stem which bears the inflorescence, a tight flat topped cluster of 4 to 17 fuzzy flower heads composed exclusively of disc flowers, with no ray flowers. The basal leaves are petiolate, oval to roundish, 3.5 to 7.5 centimeters long and 1.5 to 3.5 centimeters wide, with 3 to 7 prominent veins. The under side of the leaves is covered in thick silvery hair. Additional leaves along the stem are lanceolate and smaller. The fruit are cypselae with a pappus of white bristles.
''Antennaria plantaginifolia'' is dioecious, meaning that the male and female flowers are borne on separate plants. It often forms colonies, sometimes consisting entirely of male or female plants. It does so in part through vegetative reproduction. Stolons emerging from the basal rosette take root and develop into new plants.〔(【引用サイトリンク】url=https://gobotany.newenglandwild.org/species/antennaria/plantaginifolia/ ) Copyright © 2011-2013 New England Wild Flower Society (http://www.newenglandwild.org)〕〔Britton, Nathaniel Lord & Brown, Addison (1913).
