ETYMOLOGY: Alocasia cucullata is named after the latin ‘cucullatus’ which means hooded, likely referring to the leaf shape
NOTES:
Alocasia cucullata is one of the oldest known species of Alocasia, published under the genus Arum, as the genus Alocasia did not exist yet, in 1790
This plant is one of the smaller growing types that we consider to be in the same group as Alocasia odora, based on inflorescence morphology and overall growth habit. Alocasia cucullata has been crossed with A. odora and A. odora ‘California’ and the progeny are typical for crosses within this group. A. cucullata is known for throwing pseudoblooms, but it does produce regular inflorescences as well. It is also one of the few Alocasias that branches naturally, usually after a blooming cycle. Compare the leaves on this plant with the A. odora "Indian" and you will see why it is sometimes refferred to as a "giant cucullata".
Alocasia cucullata is used externally for detoxifying viper bites and are also used for treating abscesses, rheumatism, and arthritis. It is an important good-luck plant in Buddhist temples in Laos and Thailand.
In some parts of India, the rhizomes of Alocasia cucullata are also eaten and referred to under the umbrella term chamagadda (also refers to Colocasia esculenta rhizomes)
