    1. Reviewed by Tom Chester    Apr 4, 2004

    Action: changed name from "Calyptridium monandrum" to "Achyronychia cooperi "

    Reviewer's comments:
         "This plant cannot be Calyptridium monandrum because the leaves are opposite, not alternate, the flowers are far too showy, and the flowers are blooming all at once, not in sequence. Although I cannot key the plant from the picture, it looks exactly like the same photographer's other images of Achyronychia cooperi, which he took three years later."
