Lc. Colorama 'The Clown' ? , February, 1982. Some of the unlabeled slides are hard to classify as either Lc. Colorama or Lc. Prism Palette. With further research, it may be possible to identify some of them with plants shown in other slides that are labeled. Most of the time, slides labeled Lc. Prism Palette have petals that overlap significantly, and those labeled Lc. Colorama have petals that generally do not overlap, but there may be exceptions.
