Anemone richardsonii
''Anemone richardsonii'', commonly known as Yellow thimbleweed, is named after a Scottish naturalist, Sir John Richardson (1787–1865) who found it on Franklin’s expedition to the Arctic.〔 It is a perennial, deciduous plant that blooms in mid to early June.〔
==Description==
Yellow thimbleweed is recognized by its small single yellow flowers. These flowers are considered perfect, which means they have both male and female reproductive organs. The flower lacks petals but has yellow sepals that act as petals and it has a superior ovary.〔 The flower sits on a stem that can grow about high, and is pubescent (covered with tiny hairs).〔
''Anemone richardsonii'' has rhizomes (underground stems) which are thread-like with stalked leaves that are palmately lobed.〔 It also has stem leaves that are 3-parted and sharply toothed in a whorled arrangement below the flowers.〔
The flower develops into an achene (a dry fruit), which is generally small, long.〔 It is sub-spherical (nearly round), lacks hairs, and is hooked at the tip.〔 The fruit of the yellow thimbleweed is dispersed by wind and has a style that aids in flight.〔
