Matinal selfing in Camissonia lacustris




Selfing in Camissonia benitensis (Taylor 1990) was found to be direct and occurred before the flower bud opening. Here, I report the same similar matinal selfing in Camissonia lacustris, based on cultivated material derived from JEPS109727 collected at Wawona, Yosemite National Park.



Plants were sown out-of-doors in Aptos, CA on October 1st 2010. On March 30, 2011 the first flowers began to open. The photograph is of an unopened bud taken in early am, before opening. At this stage, the night before opening, the anthers are adherent to the spherical stigma, with abundant pollen. Under magnification, pollen tubes were observed under high magnification.
