Types of Leaves according to their base
- Sharp leaves: Acutely angled leaves.
- Roped Leaves: refers to leaves that have a heart-shaped base
- Dimmed Leaves: They’re the leaves that start to narrow as they get closer to the base.
- Auricular Leaves: The leaves with auricles at the base, as the name implies.

What is the name of leaves on plants?

The flytrap’s leaves can tell the difference between a raindrop and a fly – they only close when something living is between their jaws. Meanwhile the small, scaly leaves of a cypress can survive for many years, steadily feeding the tree with food and moisture.
What is a sheath type of grass?
Grasses vary widely but most of them have a distinctive form of leaf. This is the sheath style, consisting of very long, slim leaves that grow from the base of the stem and wrap around it. Grasses may have a single leaf per plant, or many; sometimes the base of the stem will be wrapped by multiple leaves that fan out higher up.
Why are leaves important to trees?
In fact, really, they’re what most of the main parts – the trunk and the branches – exist to support; the main purpose of a tree is to lift its leaves up to where they can catch the sunlight. It’s leaves that keep a tree alive. They collect carbon dioxide, which photosynthesis converts to sugars and oxygen. They absorb water vapor from the air. They can also store food and water, provide protection or carry out many other functions to help the tree survive.
What is a leaf in fall?
Think “leaf” and the first thing that comes to mind is probably a flat green item, with a stem at one end and veins running through it. That’s the sort that changes color in fall then lands in your yard, but there are other kinds of leaf too. Knowing a little about them can be very useful to a gardener, so here’s a quick run-down on the types you’re most likely to see.
How many lobes does a leaf have?
At the tip, though, it has two lobes either side of a hinge.
Three Primary Types of Leaves
There are billions of leaves globally and thousands of different expressions and shapes. However, these large numbers are deceiving since there are only three primary types of leaves. Every type, shape, and category falls into one of these two main types. The major typologies are needle-like single leaves and compound leaves.
Conifers vs. Deciduous Trees
The first step to identify what kind of tree you have is to figure out if it has needle-like leaves or not. Conifers will always have needle-like leaves. Sometimes these behave differently, but they still signify a conifer instead of a deciduous tree. For example, some needles will fall off seasonally instead of staying attached to the tree.
Leaf Shapes
Other than these three main leaf types, there are many subcategories. Identifying any plant species becomes much easier if you can figure out precisely what kind of leaf shape it has. We list each of these and describe them to understand them and some tree species they represent.
Leaf Structure
A leaf might seem like a simple structure. However, each leaf has specific parts that function together to give it its full identity. Each of these sets leaf patterns apart from other categories. The main four parts in leaf anatomy include the apex, margin, surface, and base. We will break each one of these apart and their identifying categories.
How Leaves Function
Leaves primarily function to produce energy for the plant by means of photosynthesis. The greenness of a leaf is determined by the amount of chlorophyll it has. Chlorophyll is a substance that can allow the leaves to absorb energy from light. It changes UV rays into usable energy, much like our bodies change calories from food into usable energy.
The Life Cycle of Leaves
Leaves of all kinds, whether deciduous or evergreen, start as a bud. These are often the sign of spring since you can so clearly see them when the tree is otherwise bare. However, most trees continue to grow and lose leaves throughout the growing season.
Interesting Facts about the Types of Leaves
There are certain plants with enormous leaf structures. Since leaves are very important for photosynthesis, it is sometimes necessary for large plants to produce large leaves. Large leaves can result from a ground cover plant growing larger to maximize its chance to interact with sunlight.
What are the different types of compound leaves?
Types of compound leaves. From left to right: pinnate leaves, palmate leaves and double pinnate leaves.
What is a simple leaf?
If there is a node, then you have a simple leaf, whereas a lack of node indicates it is a compound leaf . Examples of trees with compound leaves include ash trees, walnut trees, hickory trees, and horse chestnut trees. There are a number of types of compound leaves, and knowing about them can help make tree identification easier.
What are the veins on a leaf?
All types of leaves have a central vein called the midvein or midrib. Small veins or capillaries branch out from the midvein to form intricate patterns in the leaf structure. Some patterns in tree leaf venation include the following: 1 Pinnate veins branch out in opposite directions from the central vein that runs the length of the leaf 2 Palmate capillaries branch out from the midvein to form the shape of a leafless tress 3 Rotate veins look as if they branch out in all directions from a central point and look like spokes on a wheel 4 Dichotomous veins branch out in pairs to the edge of the leaf
What is the name of the indentation between two lobes of a tree?
The most easily identifiable type of tree leaf is the lobed variety. These leaf blades are made up of earlobe-like shapes, but they form a single leaf. The clefts or indentations between the lobes can be deep or shallow depending on the type of tree. The space or indentation between two lobes is called sinus.
What are the leaves on a palm tree called?
Palmate leaves (compound leaves) Palmate leaves have a number of leaflets growing at the end of the leaf stalk. These compound leaves usually look like the shape of a hand with a palm and fingers. That is why they are called palmate leaves. Trees that grow palmate leaves include horse chestnut and buckeye trees.
How many leaves are there in a whorled tree?
However, instead of having just 2 leaves in an opposite arrangement, there are 3 or more leaves growing from each node on stems with whorled leaves. There are not many trees or shrubs which have whorled leaves.
Why are leaf veins important?
Leaf veins are important to transport nutrients to all parts of the leaf. The veins in each leaf also play an important role in photosynthesis.
What leaves have smooth edges?
Sinuate leaves have little curves with smooth edges like waves.
What is an acicular leaf?
Acicular leaves: needle-shaped. Several times longer than wide; ending sharply at the apex.
What is a hastate leaf?
Hastate leaves: halberd-shaped. Remembering to that old fashioned weapon which was a combination between a spear and a battle-ax. Wider at the base but with lobes ending sharply.
What is a petiolated leaf?
Petiolated leaves are those that have a petiole. This can be different in length from one plant to another.
What does "whorled" mean in plants?
whorled: Several leaves disposed at the same level around the stem.
Which leaves diverge from the main point such as the fingers do in the palm of the hand?
Palmate leaves: The nerves diverge from the main point such as the fingers do in the palm of the hand.
Do simple leaves have divisions?
Simple leaves show an undivided blade or, in case it has divisions, they do not reach the midrib.
