Subject : 	[Aroid-l] Xanthosoma violaceum

Dear Jani,

I have seen photos of Xantho. violacium in bloom, but we must remember that ALL the aroids which are cultivated as food crops are in a confusing state re: their taxonomy, Dr. Eduardo Goncalves (Brazil) is working on trying to determine which names are valid, etc., and maybe we will have answers soon. To explain how mixed up the names on these plants are, Eduardo and I were walking near the cafe at Fairchild Gardens a few years ago during one of his visits, I pointed out to him a large plant of a Xanthosoma sp. with a bullate leaf-surface who's rhizomes are COMMONLY sold as food in Miami and throughout Florida as 'malanga blanca', I had been told that this plant was X. saggitifolium and had heard it called that since I first became interested in aroids. After just a glance, Eduardo said 'that plant is NOT X. sagittifolium, it is X. robustum'. In the case of what is being called X. violacium, I suspect that there are more than one species involved, and for certain that there are at least a couple of different clones or varieties involved in this complex, some w/ darker more purple petioles and leaves, some w/ lighter purple parts.

Good Luck and Merry Christmas,


>>Hi All,

Is that true Xanthosoma violaceum never flowers? Has anybody seen it in flower?
