Answers
Leaf with smooth surface: Salix caroliniana or commonly known as Southern Willow is a plant which has smooth leaves. The simple smooth-edged narrow leaves are 2-4 m long, green above and whitish underneath.
Leaves like Bougainvillea, have rough surfaces. Leaves with reticulate venation can also be considered as rough.
The leaves of succulents hold moisture, which is also why most plants with fleshy leaves also need less water. When plants with fleshy leaves are under watered, you may see their leaves become less thick or shriveled, because they are using their moisture reserves to hydrate themselves.
The spine is technically a modified, sharp-pointed leaf. Since it has a bud in its axil, the spine occurs in the relative position of a leaf. Some spines are called "stipular spines" because they are modified, sharp-pointed stipules at the base of a leaf.
