The Acacia obtriangularis, also called the Lawley River wattle, is a type of shrub. It belongs to the Acacia family, which is known for its many different kinds of wattle plants. This specific wattle is found only in a small part of north-western Australia.
What it Looks Like
This shrub usually grows to be about 1.5 to 2 meters (about 5 to 6.5 feet) tall. It stands up straight. Its small branches have tiny, soft hairs on them. It also has thin, pointed parts called stipules that curve upwards. These are about 2 to 3 millimeters long.
Like most Acacia plants, it doesn't have regular leaves. Instead, it has special flattened stems called phyllodes. These phyllodes are always green and have a unique triangular shape. They are about 3 to 5 millimeters long and 2 to 3 millimeters wide. You can often see six to eight faint lines, or nerves, running along them. The plant blooms around March or April, producing bright yellow flowers.
About its Name and Family
Scientists officially described this plant in 2013. The botanists Bruce Maslin, Matthew David Barrett, and Russell Lindsay Barrett gave it its scientific name. They wrote about it in a science journal called Nuytsia.
The Lawley River wattle is part of a larger group of plants called the Acacia deltoidea group. However, it's easy to tell it apart from other plants in this group. It has flower spikes that are different. Its closest relatives are two other wattle plants: Acacia froggattii and Acacia vincentii.
Where it Lives
This wattle plant grows naturally in a small area of the Kimberley region in Western Australia. There is only one known group of these plants. It covers a few square kilometers near the mouth of the Lawley River. You can find it growing in sandy soil that sits on top of sandstone rock.
