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.

nubicum vs Typhonium venosum 'IndianGiant'?
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.
