Barnardia is the most primitive of the proposed new genera in the split up of Scilla. This new genus in the Hyacinthaceae family consists of species which flower in autumn before the leaves have developed. Bracts and bracteoles (smaller, secondary bracts) are present. For more information about the proposed Scilla changes consult Julian Slade's post. Kew accepts this genus and list two species: Barnardia japonica and Barnardia numidica.
Barnardia japonica syn. Scilla japonica has tiny blue flowers and blooms in fall.
Barnardia numidica is from North Africa.
Barnardia scilloides syn. Scilla scilloides (sometimes incorrectly called Scilla chinensis) is not accepted by all as some believe this species should be sunk into Barnardia japonica (syn. Scilla japonica.)
