ABSTRACT:

For many plant fanciers, the image of tropical lushness with its abundant humidity and dense exotic vegetation, is conveyed vividly by the aroids known as Alocasias. However, the widespread enjoyment of them by gardeners and plant enthusiasts has been significantly hindered by the tenderness and apparent fussiness of the more desirable species. As plant breeders, therefore, we saw a need for the development of hardier, more interesting alocasias with ability to withstand ordinary abuse as well as outdoor growing conditions, at least in southern Florida and California. The recognition of this need, along with a desire to learn more about the alocasias as a genus, were the main objectives of the work described herein.
