42 species transfers are made from Amaryllis to Hippeastrum in accord
with the decision, at the Fourteenth International Botanical Congress
in 1987, on the application of the former name to a South African genu
s. This completes the validation of combinations required in Xippeastr
um, and will thus aid nomenclatural clarity and enable botanists and h
orticulturists to refer to these species by their correct names.
