Welwitschia is indeed a tree in the botanical sense of the word. Have you
ever seen one in your reality?
They don't grow wild in Toronto.

However, the last time I was in the Royal Botanical Garden in Hamilton, which
is on the way to Toronto, they had one. They even had an olive tree.
As I mentioned before, the reason Welwitschia doesn't look like a tree is that
much of its trunk is underground. It is a member of the order Gnetales, which
may be changed to a subdivision. It is related to Gnetum & Ephedra. They are
peculiar plants somewhere between the angiosperms and gymnosperms, but closer
to the conifers.

Yes, olive trees are trees.

That might sound better if it actually had a trunk

Gnetales by definition is an order (ending -ales).
The rank of a taxon with only three genera does not seem a very interesting
topic.

No. Welwitschia, Ephedra and Gnetum are Gymnosperms. Have been just about
forever. Conifers are another group of Gymnosperms.

So that means Rinkytink must be a nut!!!!

Affinities of other living Gnetales to Welwitschia do not help understand
the genus at all because they too are highly specialized in their mode of
growth. Ephedra are coralliform shrubs while Gnetum are woody lianas.

Welwitschia has a single woody stem arising from a deep taproot. The
flowering crown is raised well above the ground level on a woody trunk. It
most definitely is a tree.

Seems you are once again in full troll mood, Rinkytink.

What's the matter? Did your pet rat die?

No matter what you say, up isn't down and black isn't white.
