Well, the other day I bought a few unusual Colocasia one was variegated and
another has red streaks down the stem. They were sold under their Hawaiian
names. kumu, maea, lehua. Here is some information I got off a site about

Some years ago there was - and probably still is - a good collection of taro
cvs at the Harold L. Lyon Arboretum of the University of Hawaii on Oahu. I
have photos of a several cvs and one of Lehua is in Aroids - Plants of the
Arum Family (first edition). There's also some info on them in Chapter 9.
It's interesting to know that some of these cvs are now being sold as
ornamentals. Samoa and other islands have different ones again.

Hello to all
I have learn also that there are some cross between colocasia ans alocasia(s
this not
a work from a man in japan?)But alocasia ans colocasia are really
near..;!Xanthosoma and caladium are not so near that it was supposed some
years before,for what i have learn about this subject.But sure there are on
the list someone

Hi Danny,

I am no expert on genetics, like you I am but a lover of plants (and other a
few other things!) but you are correct--Colocasia and Alsocasia do seem to
be closely related, and that they could be crossed would seem to confirm
this close relationship ( but from memory it was reported that very few seed
were produced, and even fewer germinated, and that the seedlings were weak).
Caladiums and Xanthosomas would seem to be closely related due to their
external apearance, but there are MANY differences, for instance their
pollen is quite different, Caladium pollen is shed in monads (one large
'ball'), while Xanthosoma pollen is shed in tetrads (several 'balls' stuck
together). This would seem to be a barrier to them crossing. Other
genera with pollen similar to each of these might be a better bet, but even
within genera with seemingly similar pollen there are barriers, for instance
in the two clearly closely related genera Xanthosoma and Chlorospatha, both
have pollen shed in tetrads, but the pollen is different in texture and
size, and because of the size and shape of their respective
inflorescences/spathes, it is suspected that different insects are involved
as their respective pollenators in nature, so this also would be a barrier.
Mother Nature is no fool!

Some of the Aroid crosses proposed on this list would almost be the
equivalent of crossing an Elephant with a bat, using the logic that since
both are mammals, they will cross.
Good luck,

Hello this is Brian Williams. I personally put typos in my messages to make
sure I am still human.

To be a human you have to make mistakes.
So I believe I am super human. LOL

Hello Aroiders:
Alsocasia is a good bilingual pun, too. Also (English) casi a (Spanish)
might mean "Also almost at".
