By most definitions bonsai are not trees.
It is irrelevant whether they will grow out to become trees (when released
from their torturer / benefactor). A seedling may grow out to be a tree

but
is not itself a tree.

There is a word to describe bonsai, i.e. "bonsai" (sometimes missspelled
"banzai"). This is not a taxonomic term.

You should go to the library more often. You might actually learn something
new! You can't get all your info from reading old copies of "Organic
Gardening", babe!!

You must never have actually read anything on Welwitschia itself and all
your info is second-hand innuendo.

Is it true that in Oz you look at Baobobs standing on your head so that they
can seem to grow right-side up?

Sorry about your not being able to get a woody, bloker.

All trees are plants.

Carica papaya does have a woody trunk and is a tree. Maybe not as woody

as
some other arborescent plants but that is just a matter of degree.


Bloke I know who spent some years breeding the things always claimed
they had no lignified tissue, therefore not "woody". (And after
cutting down many pawpaw trees with a blunt cane knife over the years,
I can confirm they are not in the least woody -- at least as far as
people here in Oz understand the term. YMMV.)

A woody trunk makes arborescent palms trees. The presence or absences of
branches doesn't matter.

Who said bonasi weren't trees? It wasn't me.

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.

Why not? They meet all the criteria except size, and as I said before, they
REPRESENT a full size tree. Are you going to suggest that a chihuahua is not a

Size is part of most definitions, and bonsai are well short of the minimum

You may as well ignore the nonsense Rinkytink says. It is obvious that he is
going out of his way to be contrary and obnoxious no matter what the facts
are. Size is relative and quantitative not qualitative. That may a major
concern when the dude is hung like a chihuahua but it isn't relative to what
defines a tree.

Absolute nonsense. Size is quantative not qualitative and not part of most
definitions.

If we go by size alone, it probably could be said that Rinkytink is too
small to be a man!!!

Actually, by definition, Welwitschia is a tree because it has a
single unbranched woody trunk!!!! That it has only two leaves
is besides the point.


Odd definition, most definitions of trees include some means of
distinguishing them from shrubs, generally height. Do you mean to
imply that if a woody plant has branches on the trunk, or more
than one trunk, that it must not be a tree? If so, there aren't
very many species that manage to be trees.


As Iris has already pointed out, the definition of what
constitutes a tree has absolutely nothing to do with height,
number of leaves or number of branches at all.

Most trees obviously do have branches arising from the trunk but
not the base.

Mulberries are actually trees not shrubs because they have a
single main woody trunk. They do not branch primarily from the
base as do shrubs.

I suppose if you actually bothered to look up the definitions of
the terms in a botanical dictionary it would boggle your mind and
incorrect preconceived notions.

There are actually many more tree species found around the world
than you will see sitting behind your 'puter looking out your
window. Try going out into the real world. You might actually
learn something on your own.


Exacly what part of Iris' description includes any definition, or even
a mention of height? I admit that she did post a definition that
mentioned height, but that was posted after your post was.

I take it you have never seen a wild mulberry. They are a great example
of branching primarily at the base. The ones that you purchase from a
nursery have been pruned to a single stem, allowing them to be trees.

I have not only looked up the term in a dictionary, but I have also
looked up a few other things... Fer instance, "tuberous root"
"taproot" and even "Netkook" (how cute, there is a picture of you
there). Here is the definition offered by The Complete Trees of North
America, by Thomas Elias: Trees are woody plants that usually grow to
at least 5 m (16 ft) tall and have a single trunk. A shrub, by
contrast, is typically a multiple-stemmed woody plant with more than
one dominant stem, and shrubs are normally less than 5 m (16 ft) tall.
Most woody plants can be identified easily as either a tree or a shrub.


If it is underground, it isn't a trunk, just like if it is underground,
it isn't a stolon. Just being woody and over 10 feet long doesn't make
something a trunk, otherwise Cucurbita foetidissima would be classified
as a tree, as its tuberous root can be much over 10 feet long, and
quite woody, with rings and everything. Mesquite, (Prosopis glandulosa)
generally is less than 10 feet tall above ground, but the taproots can
extend many feet underground (100 feet has been measured), all of those
basal branches must be fooling us, and the shrub is really a tree! Look
up Phreatophyte some time.

The one I am familiar with is that a shrub is a woody plant which
is usually under ten feet tall & has multiple stems. A tree is
usually over ten feet tall & usually has a single stem.
What about dwarf trees which are way under ten feet tall & might
have multiple trunks, like a dwarf birch? I would assume if the
standard plant is a tree, the dwarf form is also called a tree.
Tsuga canadensis 'Minuta' is still a tree, albeit 3" tall.

Quercus havardii generally only gets about a meter high, a dwarf
birch may be the result of breeding, sport, or a species tendency to
be small. If those are the cases, then it is a shrub. You can prune
elms to stay shrub sized, and they are shrubs till you let them go.
If you breed something to change its form, you have guess
what...changed its form. The T. canadensis 'Minuta' wouldn't be a
tree if it never gets over 3 inches tall, or even if it doesn't get
over 3 feet tall, just as a human dwarf or midget isn't going to
find clothes in the Big & Tall section. Still a human, but not a
giant.
