  Alocasia tigrina vs zebrina
From: "D. Christopher Rogers" crogers at ecoanalysts.com> on 2006.11.22 at 10:26:05(14836)
Well, after the heated discussion on heaters in which I learned lots
(thank you all), I thought I would ask another question, hopefully with a simple
answer.

Chris,

The A. tigrina superba has much narrower elongated leaves than the
zebrina and in addition, the leaf of the A. zebrina is of a thicker
constitution than the A. tigrina superba. I have a page on the A.
zebrina, and one on my A. tigrina hybrid, which has retained much of
the characteristics of the A. tigrina superba. See the following:

Best regards,

Hi
Lariann, thanks for the pics.

I am
afraid that I am sill not able to descry which plant I have. My plant has the lovely
petiole striping that is clear on your zebrina. However, the leave on my plant
are far narrower and longer, similar to your Brisbane tigress, but are more
triangular.

Its up to our friends in the Philippines who are able to observe live plants in the wild to decipher whether or not A. wenzelii and A. tigrina are different species from A. zebrina.
However, when I looked at these species from herbarium specimens 10 years ago, they seemed to me to intergrade in the wild. If that is the case, these horticultural forms under discussion are probably much better recognised as cultivars of A. zebrina. - JMO

are all very similar.

Hello Alistair,

Thanks for your valued opinion on these plants.
For those who are still in doubt as to the 'true identity' of the Alocasias
mentioned by Dr. Hay (below), as he suggests, for the time being, and until
the professionals in the Philippienes make a final determination, all should
be refered to as 'forms' or clones of one presently 'good' species, A.
zebrina.
I know that it is difficult for some folks sitting at home and examining two
plants that may, at face valu,e look pretty different one to the other, to
realize that IN THE WILD, in the field over many miles, a single species can
be collected in MANY variations, and human nature being as it is, that only
a very few of the most attractive plants from amongst THOUSANDS within a
population that a collector may see in nature, are brought back to
'civilization'/cultivation, and from these few plants a 'new' variety given
some cockamany new name may be distributed/sold to all the collectors in the
world. This explains why there are perhaps three different-LOOKING
Alocasia plants, perhaps all the same species, but being called by different
names. A final examination of the sexual parts of their individual blooms
may FINALLY give us the answer, if there may be three different species, OR
just three or more variations/clones of the same species of Alocasia from
within a huge and perhaps very variable population, spread over a vast area
in nature.
We on Aroid-L are so very fortunate to have the world experts like Drs. Hay,
Croat, Peter Boyce, Wilbert Hetterscheid and other experts in this field at
virtually our fingertips to answer most of our querries. Thanks guys!

I hope this helps in understanding this problem.

Julius
