I generally never indulde in 'I told you so`s" in my notes, But---
I have been preaching for years on how quickly (both in geological time AND
sometimes in just a few years!) aroids can and do mutate! Recall the VERY
rapid increase in the number of vars./clones of Colocasia esculenta on
Hawaii, which took just a few hundred/thousand years to mutate or be
increased dramatically by selective cultivation of vegetative mutations. It
has increased to many hundreds of distinct vars., as it is believed that the
earliest settlers brought just a few vars. of this food-plant with them when
they arrived during their epic canoe-journeys across the Pacific ocean.
Today there were/are several hundred recognisable clones of this plant in
Then there is the Xanthosoma sp. with the little 'frills/lips" under the
leaf blade, it will mutate so that you can not recognize a sucker or
off-shoot as being produced by the 'mother plant".
I`m a little concerned by the number of veins we can observe on the leaf
blade of Tony`s plant in his pic., vs. those on both the 'new' mutation AND
the original A. cuculata in Windy`s photos, Tony`s plant sem to have many
I highly suspect you'll find the Alocasia cucullata clone which Tony Avent
under cultivation in North Carolina (available thru PDN) to be of great
Please see: http://www.plantdelights.com/Catalog/Current/Detail/04795.html
I was so convinced a layout error had occurred when I first came across this
image that I sent Tony an email, about a month ago, suggesting someone had
swapped his images of A. cucullata and A. odora. Here follows Tony's
"I checked the images and believe it or not, they are not reversed. Our
oldest clumps of A. cucculata changed appearance dramatically as they
matured to look more like a dwarf clump of A. odora that what we typically
think of as A. cucculata. We were quite surprised, but the two photos of A.
cuculata are the same clone...just several years apart. If you look close
you'll see few immature leaves toward the top and note that even the mature
leaves still have the characteristic twisted tip of A. cuculata. The plant
pictured as A. odora is actually correct also, although it is photographed
early in the season. I wouldn't believe this either unless I'd seen the
plants in person and took the photos. Both id's have been confirmed in
person by quite a few aroid authorities."
Are we witnessing a spontaneous mutation, coincidentally occurring 7,700km
and an ocean apart? Is this particular variation genetically encoded in one
more lines of Alocasia cucullata, i.e. do these two individual plants in HI
somehow share common ancestry? I leave it to finer minds than my own to

Could proposed natural hybrid merely be an aneuploid or polyploid
seedling of Alocasia cucullata with thicker, broader leaves and more
pronounced interveinal puckering? Whatever it is it is an improvement over
plain old A. cucullata. See if it gets bigger than the standard cucullata
when it matures.

The 'thing' is off course interesant,and seem to have both
part of colocasia gigantea and alocasia cuculata....
But i don't think that the last pic(but pic number 1) is colocasia
gigantea.Colocasia have more round leaves,in
all plants that i know.This plant seem more a xanthosoma
for me.And if i know that some cross were made between colocasia and
alocasia,i don't think that it could be possible between xanthosoma and
alocasia.Mr Hay?Mr Boyce?What are thinking the experts?

I thought this might be of interest to some of you Aroiders out
there, so I thought I would share these images of something I found growing
in the yard, and the two plants I suspect this new plant came from.
In our yard, here on Oahu, we have a large patch of Colocasia
gigantea growing somewhat wild and we also have two old Alocasia cuculata
While clearing out some white ginger that was taking over, I
came upon a small plant of something that was definitely different appearing
from anything else in the yard. I cleared around it and let it grow.
It's now been about 8 months since this discovery and it is
turning out to be a really interesting plant.
The blades are developing an interesting pucker between the
veins. This characteristic is becoming more pronounced with each new blade
as they harden off.
I'll be interested in seeing if it obtains the proportions of
the Colocasia gigantea.
My only explanation for this plant is that it must be a natural
hybrid of the two.
Does anyone know if Alocasia cuculata been crossed with
Colocasia gigantea intentionally before? and what do you call an Alocasia X
Thanks, Windy Aubrey
