## Definition

describing a plant that does not have a stem. These plants often look like they are growing directly from the ground without any visible middle part.

For teachers: lacking a stem; referring to a plant that appears to have no visible axis. Often used to describe certain succulent or ground-hugging species.

## Examples

- The desert plant is acaulous, growing directly from the soil.
- In arid environments, many acaulous plants have evolved to store water in their thick, fleshy leaves rather than in a central stem.
- The botanist noted that the specimen was acaulous, with all its photosynthetic activity occurring in the broad, flattened rosettes rather than a traditional vertical axis.
