Observations by bio6kali

Small bush with brown branches and small, delicate buds. Branching/budding pattern appears alternate. Buds appear to be surrounded by tiny brown leaves that may have once been wrapped around the bud for protection - they may even be old flower petals.

Pale bark with pale brown leaves. Branching pattern is alternate, and the bark itself is smooth in texture.
Leaves are about two centimetres in length and a centimetre across at the widest.
Branches tend to be long and slender, and the trunk isn't thick or bulky.

Unfortunately we have not been able to find an ID for this plant that seemed accurate, and none of the photos of plants in the area we had available to us seemed to match up with our observations.

Opposite branching pattern. Brown attachments (seeds?) open in a bell shape. Bark is a reddish brown.
Buds were dark brown and arranged opposite from one another.
Appears to have a short base and is a well spread out plant, with tall slender branches.

Dark red-brown buds with brown bark. Appeared to have an opposite branching pattern.
The tree itself has a thick trunk with coarse grey-brown bark. The branches themselves grow quite close together and appear almost tangled.

The buds themselves seem to match the description and photos provided of Populus deltoides buds, however the photos display green buds whereas these are more red, which has caused some identification issues.

Pale bark with white buds directly opposite one another. Seeds are a light brown and very flat. The seeds are about an inch in length with a half-fan shape.
The bark of the tree is fairly smooth. The trunk is slender, estimated to be around ten centimetres in diameter and well proportioned to the rest of the tree.

Smooth red-brown bark with the occasional white marking. Branches that I observed exhibited an alternating branching pattern.
Overall structure is short, with a very short base and slender red branches.

Grey-brown bark with alternate buds. Buds are wrapped in such a way that they appear to have scales. Buds are red-brown in colour. The bark of this tree is smooth in texture.
The tree trunk is thick, but proportional to the rest of the tree.
The observations and description seems to match the ID Populus deltoides, however, the buds in our photos were red instead of green in the photos we were using as references.
