The poisonous plant Clivia is actually not a single species, but an entire genus of plants. Its scientific name is Clivia.

Here's its taxonomic classification:

* Kingdom: Plantae (Plants)

* Division: Magnoliophyta (Flowering plants)

* Class: Liliopsida (Monocots)

* Order: Asparagales

* Family: Amaryllidaceae

* Genus: Clivia

While all plants in the genus Clivia are considered poisonous, the most common species cultivated is Clivia miniata, often called the "Bush Lily" or "Natal Lily."

It's important to note that all parts of Clivia plants contain toxic alkaloids, primarily lycorine. Ingestion can lead to serious health problems including nausea, vomiting, diarrhea, and even paralysis.
