None of the above tree specimen seems to be Ginkgo biloba.

Thanks!

Dr Arvind Singh

Thank you so much for your response.

Have you any idea what trees they are? Do you think they are another type of tree dating back as Ginkgo biloba does.

I they the are more likely to be Gymnosperm?

Thanks again,

Mary

This tree in town - I think - is a Ginkgo biloba. I shall have to take a close-up picture of the leaves.

It is very difficult to identify a plant without reproductive structures. Unfortunately all the above posted specimens lack reproductive structures such as flowers and fruits. The first three images with dissected leaves is that of Alnus glutinosa ‘Imperialis’, commonly known as Cut-leaved Alder or Cutleaf European Alder.

Thanks!

According to POWO Ginkgo biloba is not found in UK.

Thanks!

Dr Arvind Singh

Thank you so much. I looked at your attachment with the maps.

I think the tree near a Church in town is Ginkgo biloba; I photographed the leaves this morning.

Yes, I do think that the other trees are 'Alnus glutinosa ‘Imperialis’ as you suggested.

Thanks again, so much,

Mary

I did botany as one of my A levels at school and loved it (and got an A for it in the finals!) So this is a really interesting discussion for me.

Did you know?

Ginkgo biloba is a typical dioecious plant. It means that male and female reproductive organs are found on two different plants. The species has separate male and female trees, with male trees producing pollen and female trees producing ovules.

Thank you so much for these web links.

I will keep looking at the Ginkgo biloba tree in our town; at the moment there are no flowers; but we always pass it on a Wednesday morning, when my husband takes me for a well deserved hot drink after our main supermarket shop! And I usually have my camera in my bag, at the ready.

Ginkgo biloba: A Treasure of Functional Phytochemicals with Multimedicinal Applications. Evid Based Complement Alternat Med. 2022 Feb 28;2022:8288818. doi: 10.1155/2022/8288818.

[Plant-based phytochemicals have been utilized for over 1000 years and serve as a major platform for novel drug discovery. Ginkgo biloba L. (family: Ginkgoaceae; English name: Maidenhair tree) is a key source of novel herbal medications containing many bioactive constituents with therapeutic efficacy. This plant species is ancient, deciduous, tall, and strong, with fan-shaped, irregularly lobed leaves, growing to heights of up to 40 meters . The genus name “biloba” refers to the tree's two separate lobes, and the genus name Ginkgo is a phonetic translation of the tree's Japanese name. G. biloba is clearly classified within the plant kingdom, and this plant is often termed a “living fossil” because, evolutionarily, it is one of the oldest seed plants . After the atomic bomb detonation in Hiroshima, Japan, in 1946, G. biloba was the first plant to germinate. Microorganisms, chemical pollutants, insects, and environmental factors have a little effect on species survival .

Ginkgo biloba is an ancient plant species that is thought to provide a variety of health benefits to living organisms and contains plenty of bioactive components, making it a chemically diversified plant. G. biloba has been shown to have a variety of medicinal and pharmacological properties, including anticancer, antidementia, antidiabetic, antiobesity, antilipidemic, antimicrobial, antioxidant, antilipid peroxidation, antiplatelet, anti-inflammatory, hepatoprotective, antidepressant, antiaging, immunomodulatory, antihypertensive, and neuroprotective effects and is frequently used to treat neurological, cardiovascular, and respiratory diseases, such as tardive dyskinesia.]

Thank you, Ai Xiao

I don't use WhatsApp but I will keep your email contact; that would be lovely.

I see that your skills are in nursing, so we probably have quite a lot in common. I'm following you on ResearchGate.
