Reply-To : Discussion of aroids

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,
Julius
