[Aroid-l] Thyphonium nubicum vs Typhonium venosum 'IndianGiant'?

From: crogers at ecoanalysts.com (D. Christopher Rogers) on 2007.08.27 at 15:42:03(16165) Hmmmmmmmmmmmmm. This is very interesting. I have T. venosum. It has very spotted petioles, but grows to 4.5 - 5 feet in my greenhouse, 3.5 - 4.5 out doors. The younger leaves are more dissect as Brian shows them, the older leaves are less so, especially in the greenhouse. Maybe I have hybrids? Maybe the different forms are clinal and my material was collected in between them? Seems like an interesting amount of variability. Any suggestions? Christophero D.

This giant form is different in over all size my plant of the regular form grow to 1 to 2 feet while this Indian Giant form grows to 4 feet tall or more. The stems are different as well the regular form is highly spotted while the giant form has much fewer spotting. The leaves on the giant form also tend to be wider as well and less dissected as the more common form. The flowers as far as I can tell at identical and this may be just a odd selected seedling or a tetraploid. Here are some photos showing the differences. -------------- next part -------------- An HTML attachment was scrubbed...
