Acer palmatum, called Japanese Maple or Smooth Japanese Maple (Japanese: irohamomiji, イロハモミジ, or momiji, 紅葉) is a species of woody plant native to Japan, North Korea, South Korea, China, eastern Mongolia, and southeast Russia. Many different cultivars of this maple have been selected and they are grown worldwide for their attractive leaf shapes and colours.
Acer palmatum is a deciduous shrub or small tree reaching heights of 6 to 10 m (20 to 33 ft), rarely 16 metres (52 ft), often growing as an understory plant in shady woodlands. It may have multiple trunks joining close to the ground. In habit, it is often shaped like a hemisphere (especially when younger) or takes on a dome-like form, especially when mature. The leaves are 4–12 cm long and wide, palmately lobed with five, seven, or nine acutely pointed lobes. The flowers are produced in small cymes, the individual flowers with five red or purple sepals and five whitish petals. The fruit is a pair of winged samaras, each samara 2–3 cm long with a 6–8 mm seed. The seeds of Japanese maple and similar species require stratification in order to germinate.
Even in nature, Acer palmatum displays considerable genetic variation, with seedlings from the same parent tree typically showing differences in such traits as leaf size, shape, and colour.

Old pictures and not so good quality , however sharing which I guess is Acer japonicum C.P. Thunberg ex A. Murray (accepted name) shot at White Monastery Kathmandu hillside Nepal on 16 March 2013 at 4700 ft.
efi page on Acer japonicum (California, USA)
I think this may be Acer palmatum Thunberg as per keys in Flora of China.

Yes this is Acer palmatum commonly known as Japanese maple
This NOT the japanese maple… this is one of the japanese maples… original Japanese maple introduced has leaves, smaller of course, but identifiable in shape and outline as typical maple… this tree’s leaves are (for lack of technical term) deeply lobated…. almost like fingers….
There are at least two species of Japanese maples: Acer japonicum and Acer palmatum. More accurately, however, Acer japonicum is downy Japanese maple, and Acer palmatum as Smooth Japanese maple.
This question was actually for .. Now I understood after … reply.
The common name Japanese maple includes at least two botanically named species
Acer japonicum and Acer palmatum which again has 3 recognized subspecies and many cultivars….(Wikipedia)
– Acer palmatum subsp. palmatum. Leaves small, 4–7 cm wide, with five or seven lobes and double-serrate margins; seed wings 10–15 mm. Lower altitudes throughout central and southern Japan (not Hokkaido).
– Acer palmatum subsp. amoenum (Carrière) H.Hara. Leaves larger, 6–12 cm wide, with seven or nine lobes and single-serrate margins; seed wings 20–25 mm. Higher altitudes throughout Japan and South Korea.
– Acer palmatum subsp. matsumurae Koidz. Leaves larger, 6–12 cm wide, with seven (rarely five or nine) lobes and double-serrate margins; seed wings 15–25 mm. Higher altitudes throughout Japan
More appropriately Acer palmatum ‘Dissectum Atropurpureum’

Yes, the cultivar ‘Dissectum’ perhaps.
Can this be Acer palmatum dissectum ‘Viridis’?
I agree with … who has named it Acer palmatum seems to be correct.
More appropriately Acer palmatum ‘Dessectum Viridis’ as per the following thread
Tree for ID : Atlanta, Georgia : 20JAN19 : AK-39 : 8 posts by 4 authors. Attachments (2)
Small tree in the hotel garden where I was staying.
Seems to be Acer Species.
its sweet gum tree: Liquidamber styraciflua. if you were staying there what prevented you from taking all the appropriate pictures?
With my limited knowledge and due respects to you, I will differ on this one.
This is definitely not Liquidambar styraciflua.
This looks more closer to Acer palmatum, the Japanese Maple.
I have posted Liquidambar styraciflua from California before.
… has taught me that tree. And whatever he has taught, is well remembered.
Ok, thanks. so which variety do you think this is? do you have the entire tree… its trunk, shape of the branches? and the canopy.
they are distinctly different in sweetgum versus most of the japanese maple grown in north american landscapes
there are at least 18 varieties that they show in this slideshow in Better homes and Gardens,
a journal for homemakers. (i think there are more)
Here is the picture of the tree.
great. the branching pattern seems natural i.e. before being pruned to human will…
your tree has one linear slender stem going straight up
with branches like hands stretched up straight pointing up
could be many things but not japanese maple.
… by now you know that in case of living things like animals and trees plants etc. there is nothing written in stone. variations galore.
but certain basic designs do prevail, most of the time. most of the diagnosis we make based on one two three or four pictures are guesses
based on patterns
I guess it is more close to Acer palmatum but not sure.

Could be Acer palmatum dissectum?

Acer palmatum Japonicum ?
pictures of the beautiful architectural stem and branches???
Let me check for more pictures.
Here are some more pictures. Hope they are helpful.
Please look at Acer palmatum ‘Bloodgood’
yes. this is Japanese maple. see how easy it becomes. the branches near the lower part of mainstem have indication of how graful they will become as it ages …
thats why we plant japanese maple. small beautiful tree with graceful branches and shapes and when leaves fall off.
all winter we have the stem and branches to look at. of course it never is quite totally without all leaves. thats the saving grace.
NOT bloodgood. you have green leaves turning orangish-red to burgundy with start of cold…
what you have is japanese maple usual larger leaf variety
Acer palmatum, very common.
