On the outstanding colchicum questions, my sources all list C. sibthorpii as an invalid synonym of C. bivonae, and the photo on the wiki could be C. bivonae, which is, however, qutie variable at least as described in the older literature; it may now be split up some. I looked at the website Mary Sue mentioned showing lots of photos of C. cupanii on Malta. I'm growing two plants under this name, one acquired from England as a bulb and one grown from seed from a Czech list. The seed-grown one looks fairly typical, and the one acquired as a builb has white flowers. The latter's color led me to suspect it was misnamed, but its pollen is yellow, and all the other miniature, fall-flowering, white-flowered colchicums I can find out about have dark anthers (e.g., C. hungaricum, which I think I have with a good identification). The leaves of the white one are correct for C. cupanii, so perhaps it's just a white form. I hope to offer it on this summer's bulb list, but I'll include my doubts about identification. It is a very good grower in the bulb frame but has not survived in the open rock garden. Jane McGary Northwestern Oregon, USA
