Hi Gang, Someone wrote that I. missouriensis has rhizomes (not bulbs), and of course they are correct. I looked back at my field notes and find that I wrote "plants clumping and close, maybe bulbs or rhizomes." I guess I have to learn to consult my notes before I write from memory to the PBS. Also, maybe I should be a bit more vigourous when I dig around the edges of clumps of plants. I sort of guessed at things that day and can see from my notes that I didn't really know if it was bulbs or rhizomes. I have to agree with Jim W. who wrote "If this list is to have educational value these crucial differences should be made clear." Cordially, Joe
