About Tremandra Plants
What Tremandra Plants Look Like
Tremandra plants are shrubs that can grow from about 0.1 to 2 meters tall. Their leaves are small to medium-sized and grow in pairs opposite each other on a small stalk called a petiole.
The leaves are simple, meaning they are not divided into smaller leaflets. They are flat and shaped like a heart or an egg, often rounded at the bottom. Older leaves can be smooth or have soft hairs on the top. The underside of the leaves is covered in fine, soft hairs. The edges of the leaves are flat and have a wavy, scalloped shape.
Tremandra Flowers and Fruit
Each flower grows by itself on a thin, thread-like stalk called a peduncle. These stalks grow from where the leaves meet the stem. Each flower has 5 small to medium-sized bracts, which are like small, leaf-like structures.
The sepals (which protect the bud) and petals (the colorful parts of the flower) are arranged in circles around the center of the flower. After the flower blooms, it forms a hairy fruit. This fruit is a capsule, about 2 to 7 millimeters long. Inside, it holds two seeds that are released when the fruit is ripe.
How Tremandra Got Its Name
Naming the Genus
The name Tremandra was first officially described in 1824. This was done by a scientist named Augustin Pyramus de Candolle. He used notes from another botanist, Robert Brown, who had described the plants earlier but hadn't published his work. De Candolle's description was published in a book called Prodromus Systematis Naturalis Regni Vegetabilis.
What the Name Means
The name Tremandra comes from two Greek words. "Trema" means "hole," and "andra" refers to "anther." Anthers are the parts of a flower that hold pollen. The name refers to how the anthers of these plants open up through a small hole to release their pollen.
Types of Tremandra Species
The Australian Plant Census officially recognizes two species of Tremandra plants as of January 2020:
Where Tremandra Plants Grow
Both species of Tremandra plants are found only in the southwestern part of Western Australia. This means they are endemic to that specific region and don't naturally grow anywhere else in the world.
