Dear All,
      It was pointed out to me in a private e-mail that the phrase "haploid endosperm" is somewhat confusing.   And strictly speaking, I guess it's not "real" endosperm if it hasn't been fertilized.  It would have been better if I had referred to it as haploid "nutritive tissue" in gymnosperms.
      Anyway, if you want to read more about Friedman's hypothesis on diploid endosperm being plesiomorphic for angiosperms, see his website at:

      ------ Cheers,
