Thyrse
A thyrse is a type of inflorescence found in certain flowering plants. It is characterized by a main axis that bears a series of cymes, which are clusters of flowers. The main axis of a thyrse is typically indeterminate, meaning it continues to grow and produce flowers over time, while the lateral cymes are determinate, ceasing growth after the flowers are produced.
Structure and Characteristics[edit | edit source]
The structure of a thyrse can be complex, as it combines elements of both raceme and cyme inflorescences. The main axis grows continuously, similar to a raceme, while the lateral branches form cymes. This combination allows for a dense and often visually striking arrangement of flowers.
Thyrses are commonly found in plants belonging to the Lamiaceae family, such as lavender and sage. They can also be seen in other plant families, including the Vitaceae family, which includes grapevines.
