Populus deltoides
, the eastern cottonwood, is a cottonwood poplar native to North America, growing throughout the eastern, central, and southwestern United States, the southernmost part of eastern Canada, and northeastern Mexico.[1]  
Populus deltoides is a large tree growing to 20–40 m (67–130 ft) tall and with a trunk up to 1.8 m (5.9 ft) diameter, one of the largest North American hardwood trees. The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. The twigs are grayish-yellow and stout, with large triangular leaf scars. The winter buds are slender, pointed, 1–2 cm long (.039–0.79 inches), yellowish brown, and resinous.
The leaves are large, deltoid (triangular), 4–10 cm (1.6–3.9 inches) long and 4–11 cm (1.6–4.3 inches) broad with a truncated (flattened) base and a petiole 3–12 cm (1.2–4.7 inches) long. The leaf is very coarsely toothed, the teeth are curved and gland tipped, and the petiole is flat; they are dark green in the summer and turn yellow in the fall (but many cottonwoods in dry locations drop their leaves early from the combination of drought and leaf rust, making their fall color dull or absent). Due to the flat stem of the leaf, the leaf has the tendency to shake from even the slightest breeze. This is one of the identifying characteristics.[2]
It is dioecious, with the flowers (catkins) produced on single-sex trees in early spring. The male (pollen) catkins are reddish-purple and 8–10 cm (2.1–3.9 inches) long; the female catkins are green, 7–13 cm (2.8–5.1 inches) long at pollination, maturing 15–20 cm (6.9–7.9 inches) long with several 6–15 mm (0.24–0.59 inches) seed capsules in early summer, which split open to release the numerous small seeds attached to cotton-like strands.[3][4][5] 
It needs bare soil and full sun for successful germination and establishment; in natural conditions, it usually grows near rivers, with mud banks left after floods providing ideal conditions for seedling germination; human soil cultivation has allowed it to increase its range away from such habitats.[5]

Populus deltoides Bartram ex Marshall is a large deciduous tree, generally 30-45 m high; leaf margin coarsely crenate with very curved sinuses, broadly cordate at base. Leaf blades broadly deltoid-ovate to ovate or ovate-cordate. Mature leaves are enough for identification of this species.
This species is popularly known as Caroline Poplar being the native of South Carolina of North America.
I had collected this on way to Mussouri from Dehradun (alt. 7000 ft). 
Thanks, ..., for all the wonderful posts.

Thanks for sharing. Is it planted in many parts of India?
..., it is probably introduced long before in India and planted along roadsides as avenue tree. This species is mostly found in Jammu & Kashmir, Himachal Pradesh and Uttarakhand.

Ficus fro ID : 090111 : AK-1: This tree was taken here at Muscat, Oman on the 12th of November,2010.
Is it Peepal tree? The leaves looked slightly different.

It is Populus, possibly P. deltoides.
It is Populus deltoides Bartram ex Marshall.
The specific epithet "deltoides" comes after the shape of  the leaf blades which is broadly deltoid-ovate

Seen at a plant nursery in Nasik on 21/3/12.
Is this also Populus deltoides?
You are absolutely right ...

Populus deltoides Bartram ex Marshall
This is a giant deciduous tree, very common in Illinois.
During early to mid-summer, the fruits split open to release their seeds. Each fruit releases about 30-50 seeds with cottony hairs. That is why it is also called Eastern Cottonwood. The seeds are distributed by the wind and can travel several hundred feet in the air. They also float on water and can travel downstream. 
Beautiful pictures! and useful information...

Eastern Cottonwood/ABDEC13 : 2 posts by 2 authors.
This tall tree is growing near my home and before yesterday, I had assumed it to be a Poplar. Picking up a fallen leaf and researching a bit I found it in Krishen's book 'Trees of Delhi' (p.105). The leaf is almost flat at the bottom edge and is triangular (an equilateral, typical of Eastern Cottonwood). Can you make out the flat leaf stalk at the joint just above my thumb?

The tree is in its winter undress but has these beautiful bright mulberry like fruits now. Thought I will share with you.

I collected two fallen flowers (?) and hollow casings from under the same tree. I brought these home and took some close ups and started a new thread in stead of the older December one. Could the casings be seed casings?

Please identify the tree, which has leaves similar to Peepal / Pipal / Sacred Fig / Ficus religiosa.
Characteristics:
Medium sized tree/ Fairly straight without much side branches.
Abundance of barks (fairly light-colored) on trunk.
No flowers/ inflorescence. At least not visible. May be not mature enough.
No milky sap (unlike the tell-tale of Moraceae/ Ficus genus)
This would be a help if habit pics and locality are revealed..
Yet, see for Populus sp.
My initial thoughts were the same. Some kind of a poplar. But but but, in Pune?
Do they survive the harsh summers of the near-tropical region? The trees in question are already 10 to 12 years old, with a height of over 15 meters. Also there are no catkins or (visible) flowers. I am baffled. Please help.
Pl. post actual images of the tree. It may help.
Here are some photographs of the tree in question: 6 images.
Help appreciated much. Thanks in advance.
Certainly looks like this poplar "Populus deltoides". But the absence of any catkins stumps me. At what stage of growth do they produce catkins? Also, can they flourish in Pune's semi-tropical climate? The office I work has at-least 20 trees like this, of fairly good growth (around 12 to 15 meters height)
Thanks for your help profoundly.

Kindly identify this deciduous tree growing in Delhi. I have not seen it flowering in Delhi.
Could it be a species of Populus?
Might be Populus nigra:
Leaf shape, margin, venation seem to match it, e.g.,
But I've not looked at the other introduced hybrids that are listed in the FAO publication and assume that the natural species are not likely to be cultivated so far south at this altitude.
Please check if it is Gmelina arborea?
Seems to be Populus, could be P.deltoides (eastern cottonwood),
According to Trees of Delhi, flowers not seen in the trees present in Delhi.
Could it be Populus deltoides?
The petiole of the leaf is flat, and there are glands at the margins of the leaves and also at the junction of lamina and petiole.
