    I am preparing the treatment of Sparganium for ed. 2 of the Jepson Manual of the Higher Plants of California. I think that S. erectum subsp. stoloniferum as defined by Cook and Nichols (1987) should be recognized for California (to B.C.(?), but am seeking more information on S. erectum and S. eurycarpum. I am working with a loan of about 50 specimens from the University of California and the collections at U. of Wisconsin, where there are few Sparganium specimens from the Pacific Coast of N.Am. or Eurasia.
    Your beautiful photograph posted by Marcella2 looks much like some specimens from coastal California and Oregon I have on loan. Are the stigmas mostly 1 per flower? What was the geographical origin of the plant? Do you have any other information on Sparganium erectum and eurycarpum in B.C.?

    Hard to say – the photographer will have to comment on a few of your questions, but to broadly answer the geographical question, it is somewhere in The Netherlands.
    We have neither of the two species in the collections here at the botanical garden. As for the genus Sparganium in British Columbia, my first instinct is to suggest you contact Adolf Ceska of Botanical Electronic News. He may redirect you to Chris Brayshaw, but I’m not certain how active he still is.
