Re: [Aroid-l] Alocasia tigrina vs zebrina

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

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

   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:

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.
How can I separate Alocasia tigrina from A. zebrina? I have a nice plant about a meter tall, no flowers, labeled A. tigrina, but looks a lot like pictures I have seen recently of A. zebrina. Any advice and literature citations would be helpful 



       Thanks heaps!
