Thyphonium nubicum vs Typhonium venosum

From: tony at plantdelights.com (Tony Avent) on 2007.08.24 at 11:57:00(16154) Aroiders: Since we named Sauromatum 'Indian Giant', I guess I'll chime in. We purchased these from an Indian Nursery about 15 years ago and noticed that they were remarkably larger than the "typical" species that we had grown from years and unique in the ways already mentioned by other observant aroiders. The differences that weren't mentioned yet are a much wider vein margin and a much larger (wider) inflorescense. This was introduced by us as a strain and not as a clone. What we found out later is that when grown beside the "typical" form is that they cross-pollinate, leading us to believe that they are simply an unusual regional ecotype. Out of several hundred hybrid seedlings which are now flowering size, we have some very interesting hybrids between the two forms that we are still evaluating. There is always the possibility that S. 'Indian Giant' is a tetraploids, but this has never been tested, but the idea of sterile triploid offspring is intriguing. I hope this helps.
