I have believed that D.Orinoco and T.Orinoco is the same species only with
the difference of the size and the height.

However I start wondering if this is the case because I found the difference of the shape of the roots of the leaves around the roots on the petioles.
As you can see from the pics that Dwarf type has egg shape and Tall type
has sharp shape.
Are they still the same species?

Yes, same cultivar/ Landrace except one is tall and the other is dwarf.

The first photo looks almost like part of the leaf has been torn off. Do all the leaves look like that?

Hi Erlend,
Yes, all leaves of dwarp type is so called egg shape, while the tall type has
sharp type leaves as the pics show. Same species does not produce different
type of leaves.
I will attach more plausible picture of the leaves of Dwarf Orinoco so that
you can compare eather other.

My plants have both kinds of leaves on the same plants I think they are the tall kind because they get up to twenty feet of stalk not counting the leaves. Older plants with two to three ft wide leaves and 6 to 8 foot long leaves have a are more likely to be sharp and younger plants have more pointed ovals although light conditions have major effect on leaf shape the low light conditions we have here now combined with record hight temperatures makes longer leaves that are narrower and these are more rounded to pointed on both ends--Philip

Good morning, Erlend!
Here are the additional pics of the shapes of the leaves of Dwarf Orinoco.
From the pics, you can see that the leaves are not torn off and are basically
so developed.
If so, isn't it funny that the same species produces two different shapes of
leaves. Or could my Orinocos be mislabelled?

You are right Stan, your photo looks just like what a dwarf orinoco should look like. Orinoco has a fair amount of balbisiana in it, so it's natural with the balbisiana shaped leaves.

But the photo of the tall-orinoco, is that a young plant? I know that the leaf-shape we talk about sometimes change as the plant matures. It's not necessarly mislabeled.
