[How to tell the difference between Toon and Ailanthus altissima]

[How to tell the difference between Toon and Ailanthus altissima]

Toon and Ailanthus may be difficult to tell to unfamiliar people, but only careful people will find it.

The taste of the two is different, this is the most intuitive judgment.

Toon tree is relatively regular in peeling, while Ailanthus trunk is smoother than shoulder.

In fact, it is still easy to distinguish, as long as you look closely, you can always find a little different.

The leaves of Toona sinensis and Ailanthus altissima are different. The leaves of Toona sinensis are light green, while the leaves of Ailanthus altissima are dark green.

1: The leaves taste different.

Ailanthus altissima leaves have a foul odor, and toona sinensis leaves have a strong fragrance.

2: The trunk is different.

The surface of Ailanthus trunk is smooth and not cracked, and the trunk of Ailanthus chinensis often peels off in stripes.

3: Vascular bundles are different.

Observing the leaf marks, there were 9 vascular bundles of Ailanthus altissima and 5 of Toona sinensis.

4: Toon is an even-pinnate compound leaf, and Ailanthus is an odd-pinnate compound leaf.

But this is not necessarily correct. There are too many toonas and leaves are also odd.

Method 1 for identifying Toona sinensis or Ailanthus altissima from the appearance of leaves.

The root of Toona sinensis is light green, and the tip of the leaf is yellow-green; the root of Ailanthus is dark green, and the tip of the leaf is gray-green.

b Toon leaves have sparse serrated edges; Ailanthus leaves do not.

c leaf number.

Ailanthus altissima is an odd-numbered leaf, and Toona sinensis is an even-numbered leaf.

That is to say, the number of leaves on each branch of Toon is always double.

For example, six pairs, seven pairs, eight pairs, and so on.

The score of each leaf of Ailanthus altissima is singular, it is always a few pairs away, and one more piece grows on the upper end, forming six and a half, seven and a half, eight and a half.

2 Identification from odor.

Take a leaf and rub it with your hand, smell what it smells like.

“樗”, commonly known as Ailanthus altissima.

Looks like toon but it smells weird and unacceptable.

3.The trunk is different.

The surface of Ailanthus trunk is smooth and not cracked, and the trunk of Ailanthus chinensis often peels off in stripes.
4.The fruits are different.

Ailanthus altissima fruits are Samara fruits, and Toona sinensis fruits are capsules.

5.Vascular bundles are different.

Observing the leaf marks, there were 9 vascular bundles of Ailanthus altissima and 5 of Toona sinensis.
Others: Toona sinensis and Ailanthus altissima.

These are two tree species belonging to different families.

It is well understood in dendrology that Toona sinensis belongs to the family Polygonaceae, and Ailanthus belongs to the family Bitteriaceae.

From the perspective of plant taxonomy, the leaves of Toona sinensis are even-pinnate compound leaves, and the leaves of Ailanthus altissima are odd-pinnate compound leaves.

The flower of toon is bisexual, the fruit is capsule, woody.

The flowers of Ailanthus altissima are heterogeneous, and the fruit is Samara.

However, the actual situation is that there are never Toona sinensis and Ailanthus sinensis, and their pinnate compound leaves, odd and even, are mixed, and there are two compound leaves on the same tree.
