Tree identification - in Prague

[Dilbertian]

Can anyone identify these trees that I saw in Prague?

One had very large heart-shaped leaves, and clusters of greeny-grey fruits.

The other had sprays of small, paired leaves and masses of creamy orchid-like flowers which it was shedding like snow. I saw many of these trees in the parks.

Heart shaped leaves with fruit at this time of year could be large-leafed limes?

Do limes grow in clusters?

From chatGPT

Based on the leaves and the clusters of fruit visible in the image, this tree appears to be a Common Hackberry (Celtis occidentalis). The Common Hackberry is known for its warty bark and small, berry-like fruits that turn from green to dark purple as they ripen. It's commonly found in various regions, including urban areas like Prague.

The characteristics that suggest it is a Hackberry include:

• The shape and arrangement of the leaves.
• The clusters of small, green, berry-like fruits.

Hackberries are known to be hardy urban trees, often used in city landscapes for their tolerance to a wide range of soil conditions and urban pollution.

The blossom one

Based on the appearance of the leaves and the clusters of white flowers in the image, this tree appears to be a Black Locust (Robinia pseudoacacia). The Black Locust is known for its compound leaves and large, fragrant clusters of white flowers.

The characteristics that suggest it is a Black Locust include:

• The compound leaves with many small leaflets.
• The hanging clusters of white, pea-like flowers.
• The overall tree structure and branching pattern.

Black Locust trees are commonly found in various regions, including urban areas like Prague, and are often used for their hardiness and ability to thrive in different soil conditions.

If I’ve understood things correctly the in-house expert here thinks the one with white flowers might be Sophora japonica and the clusters of fruit might belong to a Paulonia…

They don't mean the citrus fruit, there's another entirely different tree species called a lime as well.

That's one of the reasons botanists use Latin names for plants.

It's not either sort of lime tree though

I think the one with heart-shaped leaves is a large-leaved lime, otherwise known as linden in Europe, there are loads of them in parks in Prague apparently. They do have clusters of fruit like that.

The other one I'm not familiar with, but with the OP's description of orchid-like flowers and the shape of the leaves, it could be the black locust, which is rather oddly a member of the pea family.

This would be Tilia that was being suggested, also called Linden. Not the citrus fruit Lime.

But the fruit are wrong. Tilia have “helicopters”, a single fruit hanging from a surfboard-like wing, which gently spirals to the ground.

The other had sprays of small, paired leaves - that’s because it has compound leaves made up of small leaflets, in this case “pinnate” leaves with the leaflets paired along a central rib.

Ok, I’m not going to argue against @Yamadori who knows her trees better than I do. I can’t recall seeing a Linden with multiple fruits to a helicopter- probably because where I grew up they seemed to line every street, so were just part of the background.

Ok, I’m not going to argue against @Yamadori who knows her trees better than I do And better than ChatGPT

LOL 😂

It isn't straightforward making a positive ID of a tree that isn't particularly familiar to you without close-up views of leaves, flowers, fruits and the bark on the trunk unless you are an arborist and I'm not one of those! So I could quite easily be wrong.

Thanks for the suggestions and explanations. I had intended to go back and take a close-up of the large leafed tree, but you know how holidays are... too busy to relax! I shall research your suggestions.
