  • date of photo  Jul 27, 2006
  • location   Near Tomahawk Lake, Humphries Basin, Sierra National Forest (Fresno County, California, US)
  • family Polygonaceae
  • notes   Habit of a pistillate (female) plant of Eriogonum incanum. The perianths of fertilzed female flowers grow longer and reddish as they mature. The inflorescences of female plants also grow more open and umbel-like as they mature, whereas the inflorescences of male plants remain more tightly capitate (head-like).

    The vast majority of Eriogonum species are synoecious, meaning that each of the flowers of a typical plant have both fertile stamens and fertile pistils. However E. incanum is one of three unusual species in the genus in that it is dioecious---meaning it has staminate (male) flowers and pistillate (female) flowers residing on different plants. See comments here for more details on this interesting phenomenon.

    [Note: The different looking yellow flowers at the far left and upper right of the image belong to a different plant, Ivesia muirii. It has those dense, woolly, cyindrical leaves---AKA ''mousetails''.]
