Noun 1. A taxonomic order of bryophytes: "Order Anthocerotales" is the scientific name for a specific order of non-vascular plants commonly known as hornworts. This order is characterized by plants having a thalloid (flat and undifferentiated) gametophyte stage. In some older classification systems, this group was included within the broader class Hepaticopsida (liverworts).
Usage Examples
- Noun:
- The biologist specialized in studying the unique reproductive structures of Order Anthocerotales.
- Plants classified under Order Anthocerotales are found in moist habitats worldwide.
- The classification of Order Anthocerotales has been revised with modern genetic analysis.
Advanced Usage

- The family Anthocerotaceae belongs to Order Anthocerotales.
Variants and Related Words
- Anthocerotales (n): The abbreviated form of the full taxonomic name, often used without "order."

Notes on Meaning
This term has a single, precise meaning in scientific (botanical) contexts. It refers exclusively to the taxonomic grouping of hornworts. The reference to its past inclusion in the class Hepaticopsida is historical and highlights changes in scientific understanding; modern classifications typically treat hornworts as a distinct lineage separate from liverworts.
Noun
- hornworts; liverworts having a thalloid gametophyte; in some classification systems included in the class Hepaticopsida
