If there’s one thing Aussies know well, it’s eucalyptus trees. Also known as ‘gum trees’, these botanical wonders can be found in almost every corner of the country. While they are often used interchangeably, there are some subtle differences between eucalyptus trees and gum trees that are worth knowing.
One of the main differences between eucalyptus trees and gum trees is that not all gum trees are eucalyptus trees! Confused yet? Let me explain. ‘Gum tree’ is actually a colloquial term used to describe several different species of trees that exude gum or resin from their bark. These trees can include eucalyptus trees, as well as other species like acacias and melaleucas.
Another key difference between eucalyptus trees and gum trees is their appearance. While eucalyptus trees are known for their smooth, silvery-grey bark, gum trees can have a rough and knobbly exterior. Additionally, eucalyptus leaves tend to be long and slender, whereas gum tree leaves can vary greatly in shape and texture, depending on the species. Understanding the subtle differences between these two tree varieties can help you better appreciate the unique beauty of each!
Gum tree vs. Eucalyptus tree: An overview
While the terms “gum tree” and “eucalyptus tree” are often used interchangeably, there are some key differences between them. So, what exactly sets these two trees apart?
- Gum trees are a type of eucalyptus tree. All gum trees are eucalyptus trees, but not all eucalyptus trees are gum trees.
- One of the main differences between the two is their bark. Gum trees have smooth bark that sheds in patches, while eucalyptus trees often have rough bark that is deeply furrowed.
- Gum trees typically have narrower leaves than eucalyptus trees. Their leaves are also often more colorful, with shades of red, pink, or yellow.
Physical differences between Gum trees and Eucalyptus trees
Gum trees, known as eucalypts, are a group of flowering evergreen trees native to Australia and surrounding areas such as Indonesia, Papua New Guinea and the Philippines. While the name gum tree is used interchangeably with eucalyptus tree, there are differences between the two.
- Leaf Shape: The shape of the leaves is one of the easiest ways to differentiate between the two. Eucalyptus leaves are elongated, narrow, and typically hang vertically, while the leaves of gum trees are broad and round.
- Bark: The bark of gum trees is smooth and often sheds in patches, while the bark of eucalyptus trees is often rough and stringy.
- Flowers: Another difference between gum trees and eucalyptus trees is the flowers they produce. Gum trees produce attractive flowers in varying colors, including white, pink, orange, and red, and eucalyptus trees have clusters of small flowers that are usually white, cream, or yellow.
In addition to these differences, there are some other physical features that set these two trees apart from each other.
Gum trees often have a more compact growth habit than eucalyptus trees, reaching up to 98 feet in height. In contrast, eucalyptus trees can reach up to 330 feet tall. Gum trees also tend to have denser foliage than eucalyptus trees.
| Physical Feature | Gum Trees | Eucalyptus Trees |
|---|---|---|
| Leaf Shape | Broad and Round | Elongated and Narrow |
| Bark | Smooth and often sheds in patches | Rough and stringy |
| Flowers | Attractive flowers in varying colors | Clusters of small flowers that are usually white, cream, or yellow |
| Height | Up to 98 feet | Up to 330 feet |
| Foliage | Dense foliage | Less dense foliage than gum trees |
In summary, while gum trees and eucalyptus trees share many similarities, there are distinct physical differences between the two. These differences include leaf shape, bark, flowers, height, and foliage density.
Gum tree and Eucalyptus tree: Leaf comparison
One of the most distinct features of gum trees and eucalyptus trees is their leaves. While both belong to the same family of Myrtaceae, they have noticeable differences in their leaf shape, size, and texture.
- Gum tree leaves are typically broad and flat, with a smooth texture and a shiny appearance. They can vary in size but are typically larger than eucalyptus leaves, measuring up to 30 cm in length and 15 cm in width.
- Eucalyptus leaves are more elongated and slender, with a slightly rough texture and a duller color. They tend to be smaller compared to gum tree leaves, measuring up to 15 cm in length and 2 cm in width.
- Another notable difference is the arrangement of the leaves on the stem. Gum tree leaves are typically arranged in an alternate fashion, while eucalyptus leaves are often opposite.
Aside from their physical appearances, their leaves also differ in their functions. Gum tree leaves are known for their water-storing ability, which allows them to survive in dry and arid conditions. They also contain oils that give off a distinctive eucalyptus scent when crushed.
Eucalyptus leaves, on the other hand, are known for their oil-producing glands, which contain a compound called eucalyptol or cineole. This compound has potent antiseptic and anti-inflammatory properties, making it a valuable ingredient in many medicinal and industrial products.

| Arrangement on stem | Alternate | Opposite |
In conclusion, while gum trees and eucalyptus trees belong to the same family, they have distinct differences in their leaf characteristics. Understanding these differences can help in identifying the species and appreciating their unique qualities.
Bark Comparison Between Eucalyptus and Gum Trees
Eucalyptus and gum trees are both native to Australia and belong to the same family, Myrtaceae. While they do share some similarities in their features, one of the most noticeable differences between these trees is their bark.
Let’s take a closer look at the bark of both eucalyptus and gum trees:
Bark Texture
- Eucalyptus tree bark is known for its smooth and pale texture. The bark often peels off in thin, paper-like sheets to reveal a bright green layer underneath. This shedding process helps the tree to grow faster and absorb nutrients more efficiently.
- Gum tree bark is typically rougher and thicker than eucalyptus bark. Depending on the species, the texture can range from scaly to deeply furrowed. One of the gum tree varieties, the stringybark tree, gets its name from the long, fibrous strips of bark that cover its trunk.
Bark Color
The color of the bark can also help distinguish between eucalyptus and gum trees:
- Eucalyptus tree bark is usually white, gray, or light brown.
- Gum tree bark can vary greatly in color. Some species, like the red gum tree, have dark brown to black bark that peels off to reveal a reddish-brown underlayer.
Bark Thickness
The thickness of bark can differ between eucalyptus and gum trees:
- Eucalyptus tree bark is relatively thin and lightweight compared to gum tree bark.
- Gum tree bark is usually thicker and more durable. The bark serves as a protective layer for the tree against damage from pests and fires.
Bark Uses
The bark of eucalyptus and gum trees has many practical uses:
| Eucalyptus Bark Uses | Gum Tree Bark Uses |
|---|---|
| – Paper production | – Tannin extraction for leather production |
| – Essential oil extraction for medicinal and aromatherapy purposes | – Aboriginal tool-making |
| – Dye-making | – Construction of shelters and canoes |
Despite their differences in bark texture, color, and thickness, both eucalyptus and gum trees play an important role in the Australian ecosystem and have a rich history of cultural and practical uses.
Gum tree and Eucalyptus tree: Flower and fruit comparison
One of the key differences between gum trees and eucalyptus trees lies in their flowers and fruit. Here’s a closer look at the unique characteristics of each:
- Gum tree flowers: Gum tree flowers are usually small and white or cream-colored. They typically have five petals and are borne in clusters. In some species, the flowers are followed by the appearance of small fruit capsules that contain the tree’s seeds.
- Eucalyptus tree flowers: Eucalyptus tree flowers are typically larger than gum tree flowers and come in a wider range of colors. They can be pink, white, yellow or red, and are usually made up of many small flowers on a single stem. Following pollination, the flowers are typically replaced by woody capsules, known as gumnuts, that contain the tree’s seeds.
In terms of their fruit, there are also some differences between gum trees and eucalyptus trees:
- Gum tree fruit: As mentioned above, gum tree fruit typically takes the form of small capsules that contain the tree’s seeds. These capsules often have a woody texture and can persist on the tree for long periods of time.
- Eucalyptus tree fruit: Eucalyptus tree fruit, or gumnuts, are also woody capsules. However, they tend to be larger than gum tree capsules and can take on a range of interesting shapes and sizes. Some species of eucalyptus tree fruits look like apples or pears, while others resemble small bells or urns.
Conclusion
While gum trees and eucalyptus trees may share many similarities, their flowers and fruit are a clear point of differentiation. Gum tree flowers tend to be small and white, while eucalyptus tree flowers can be larger and more colorful. Similarly, gum tree fruit takes the form of small capsules, while eucalyptus tree fruit can be more varied and interesting in shape and size. Understanding these differences can be valuable for anyone interested in identifying and appreciating these fascinating trees.
