napellus

Napellus is a genus of flowering plants primarily associated with the family Ranunculaceae, commonly known as the buttercup family. The name "Napellus" is derived from the Latin word *napus*, meaning "cabbage," which may refer to the plant's leafy appearance. However, the genus is not widely recognized in modern botanical classifications, as many of its species have been reclassified under other genera, such as *Ranunculus* or *Thalictrum*.

The most notable species historically linked to *Napellus* is *Ranunculus bulbosus*, commonly known as the bulbous buttercup. This plant features bright yellow flowers and bulbous roots, making it distinct among its relatives. It is native to Europe and parts of Asia and has been introduced to other regions, including North America, where it is sometimes considered invasive due to its rapid spread in disturbed habitats.

Buttercups in the *Napellus* lineage are typically herbaceous perennials with palmately lobed leaves and showy, solitary flowers. Some species produce toxic compounds, such as protoanemonin, which can cause skin irritation or gastrointestinal upset if ingested. Historically, certain parts of these plants have been used in traditional medicine, though modern scientific validation is limited.

Due to taxonomic revisions, the genus *Napellus* is rarely used in contemporary botanical literature. Most references now direct researchers and enthusiasts to the broader *Ranunculus* genus, which encompasses a vast array of similar-looking species. For identification and study purposes, consulting updated botanical databases or field guides is recommended.
